Provisional Mortality by Multiple Cause of Death

Provisional Mortality Statistics
by Multiple Cause of Death
and by Single Race,
for 2018 through Present

Summary:		Provisional mortality statistics by multiple cause of death are available on WONDER at the national, state and county level by single race categories, for deaths occurring in years 2018 through last week. Data are based on death certificates for U.S. residents. Each death certificate contains a single underlying cause of death, up to twenty additional multiple causes, and demographic data. The number of deaths, crude death rates, age-adjusted death rates and 95% confidence intervals for death rates can be obtained by cause of death (4 digit ICD-10 codes, 113 selected causes of death, 130 selected causes of infant death, drug and alcohol related causes of death, injury intent and injury mechanism categories), place of residence or place of occurrence (national, region, division, state, and county, and urbanization categories for counties) age (single-year-of age, 5-year age groups, 10-year age groups and infant age groups), race (3 lists of single race categories), Hispanic ethnicity, gender and year. Data are also available by place of death, year, week, or month of death, and whether an autopsy was performed. Privacy policy: Statistics representing one through nine (1-9) deaths are suppressed, in the provisional mortality online database for years 2018 and later. Additional privacy constraints apply to infant mortality statistics for infant age groups and live births denominator population figures. See Assurance of Confidentiality for more information.
Mortality data:		About Mortality Data Sources: The mortality data are based on information from all death certificates filed in the fifty states and the District of Columbia. Deaths of nonresidents (e.g. nonresident aliens, nationals living abroad, residents of Puerto Rico, Guam, the Virgin Islands, and other territories of the U.S.) and fetal deaths are excluded. Mortality data from the death certificates are coded by the states and provided to NCHS through the Vital Statistics Cooperative Program or coded by NCHS from copies of the original death certificates provided to NCHS by the State registration offices. For more information, see Technical Appendix from Vital Statistics of United States: 1999 Mortality. About Provisional Mortality Statistics: The provisional deaths are based on a current flow of mortality data in the National Vital Statistics System. National provisional counts include deaths occurring within the 50 states and the District of Columbia that have been received and coded as of the date specified. It is important to note that it can take several weeks for death records to be submitted to National Center for Health Statistics (NCHS), processed, coded, and tabulated. Therefore, the provisional data may be incomplete, and will likely not include all deaths that occurred during a given time period, especially for the more recent time periods. Death counts for earlier weeks are continually revised and may increase or decrease as new and updated death certificate data are received from the states by NCHS. For more information, see Technical Notes for Provisional Mortality below. About suppressed data and unreliable rates: Statistics representing one through nine (1-9) deaths are suppressed, in the provisional mortality online database for years 2018 and later. See Assurance of Confidentiality for more information. Rates are marked as "unreliable" when the death count is less than 20. About cause of death classification: The underlying cause-of-death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." Underlying cause-of-death is selected from the conditions entered by the physician on the cause of death section of the death certificate. When more than one cause or condition is entered by the physician, the underlying cause is determined by the sequence of conditions on the certificate, provisions of the ICD, and associated selection rules and modifications. Causes of death are classified in accordance with the International Classification of Disease. Deaths for 1979-98 are classified using the Ninth Revision (ICD-9). Deaths for 1999 and beyond are classified using the Tenth Revision (ICD-10). Beginning with data for 2006, the valid ICD-10 codes used to classify causes of death changed. Effective with the 2006 data year, 18 codes were introduced as valid causes of death, and 4 codes were discontinued. Effective with the 2007 data year, 4 codes were introduced as valid causes of death, and 2 codes were discontinued. See ICD-10 Changes for more information. Beginning with data for 2001, NCHS introduced categories U01-U03 for classifying and coding deaths due to acts of terrorism. The asterisks before the category codes indicate that they are not part of the International Classification of Diseases, Tenth Revision (ICD-10). Description of the specific 4-digit codes can be found at NCHS Classifications of Diseases, and Functioning & Disability: Appendix I. Deaths classified to the terrorism categories are included in the categories for Assault (homicide) and Intentional self-harm (suicide) in the 113 cause-of-death list. Additional information on these new categories can be found at NCHS Classifications of Diseases, and Functioning & Disability: Classification of Death and Injury Resulting from Terrorism. About race and ethnicity reporting: Race and Hispanic origin are reported separately on the death certificate in accordance with standards set forth by the Office of Management and Budget. The American Indian or Alaska Native race category includes: North, Central, and South American Indians, Eskimos, and Aleuts. The Asian or Pacific Islander race category includes Chinese, Filipino, Hawaiian, Japanese, and Other Asian or Pacific Islanders. Hispanic origin was not reported on the death certificate for some deaths. On the mortality file, missing Hispanic origin information is coded as "not stated". There is no corresponding population figure for this group. Therefore, deaths with Hispanic origin not stated are excluded when death rates are calculated by Hispanic origin. Information included on the death certificate about the race and Hispanic ethnicity of the decedent is reported by the funeral director as provided by an informant, often the surviving next of kin, or, in the absence of an informant, on the basis of observation. Race and ethnicity information from the census is by self-report. To the extent that race and Hispanic origin are inconsistent between these two data sources, death rates will be biased. Studies have shown that persons self-reported as American Indian, Asian, or Hispanic on census and survey records may sometimes be reported as white or non-Hispanic on the death certificate, resulting in an underestimation of deaths and death rates for the American Indian, Asian, and Hispanic groups. Bias also results from undercounts of some population groups in the census, particularly young black males, young white males, and elderly persons, resulting in an overestimation of death rates. In " Quality of death rates by race and Hispanic origin: A summary of current research, 1999," the authors estimate that the misclassification and under-coverage result in overstated death rates for the white and black populations (1% and 5%, respectively) and understated death rates for other population groups (American Indians, 21%; Asian or Pacific Islanders, 11%; and Hispanics, 2%). See also The validity of race and Hispanic Origin reporting on death certificates in the United States. For deaths in 2018-2019, mortality data are available by "single race" categories in three lists, with 6, 15 or 31 distinct options. For 1979-2002, all 50 States and the District of Columbia collected race data on the death certificates using four single-race categories (American Indian or Alaska Native, Asian or Pacific Islander, Black, and White) in accordance with the 1977 OMB standards, allowing only a single race to be reported. Beginning with the 2003 data year, some States began collecting race data in accordance with the 1997 OMB standards, allowing one or more of five race categories to be reported. In order to provide uniformity and comparability of mortality data during the transition from the single-race format to the multiple-race format, NCHS is "bridging" the race responses of those for whom more than one race is reported (multiple race) to one of the single-race categories. The bridging procedure is similar to the procedure used to bridge multiple-race population estimates. Multiple-race decedents are imputed to a single race (White, Black, American Indian or Alaska Native, or Asian or Pacific Islander) according to their combination of races, Hispanic origin, sex, and age indicated on the death certificate. The imputation procedure is described in detail at NCHS Procedures for Multiple-Race and Hispanic Origin Data. For more discussion of race and ethnicity data, see Race and Ethnicity Questions. About "Not Stated" age or ethnicity: Deaths of persons with "Not Stated" age or ethnicity are included in the "All Ages" and "All Hispanic Origins" categories. Data in the "Not Stated" groups are not distributed among the other groups. Data in the "Not Stated" age group are not included in age-specific counts, age-specific rates or in any age-adjusted rates. Data for the "Not Stated" age category or the "Not Stated" Hispanic Origin category cannot be combined with any other specified age group or Hispanic Origin categories. Death rates are not calculated specifically for the "Not Stated" groups because there are no corresponding population denominator data for these groups. Effective April 7, 2011 for Multiple Cause of Death mortality data on CDC WONDER: data for the "Not Stated" age category or the "Not Stated" Hispanic Origin category cannot be combined with any other specified age group or Hispanic Origin categories.
Population data:		The population estimates are U.S. Census Bureau estimates of U.S. national, state, and county resident populations. The 2018-2019 population estimates are six single race postcensal estimates of the July 1 resident population. For more information, see Population Data Sources. NCHS live-birth data are included for "Infant Age Groups" so that infant mortality rates can be calculated. The number of live births and the population estimate for the "under one year of age" group differ slightly, thus death rates may differ slightly when compared. For more information, see Mortality for Infants.
Source:		The Multiple Cause of Death data are produced by the Division of Vital Statistics, National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC), United States Department of Health and Human Services (US DHHS). See Data Source Information.
In WONDER:		You can produce tables, maps, charts, and data extracts. Obtain death counts, crude death rates, age-adjusted rates, 95% confidence intervals and standard errors for rates, and percentage of total. Select specific disease and demographic criteria to produce cross-tabulated mortality measures. Data are organized into three levels of geographic detail: national, state (including multi-state regions and divisions) and county. The population estimates used as the denominator for rate calculations are also shown. You can limit and index your data by any and all of the variables.

How? See How do I organize my data? for more information.

Hints:

About rates:
Rates and population estimates are available by 6 race categories. County-level rates are available by 5-year age groups. Please see About Single Race Constraints for Rate Calculations for more information.
About age-adjusted rates:
When age-adjusted rates are calculated, you cannot group the data by Age Group.
About Multiple Cause of Death:
When the data are grouped by Multiple Cause of Death, the table shows a row for each cause of death mentioned, including the number of deaths and rates. Although each death certificate has only 1 Underlying Cause of death, up to 20 causes can be indicated in the Multiple Cause of Death field. Thus, the total count by "any mention" of cause in the Multiple Cause of Death field may exceed the actual number of dead persons in the selected population.
About charts:
You cannot make charts when your data has more than two By-Variables.
About maps:
To make a map, you must request data with a geographic location variable, such as State or County, as a "By-Variable." Then click the Map tab.

Death Counts

The death counts in the data represent deaths that occurred in the 50 United States and the district of Columbia, for the legal place of residence of the decedent. See Mortality data for more information.

Notes:

Death counts are suppressed for sub-national data representing zero to nine (0-9) deaths. See Assurance of Confidentiality for more information.
The death counts reported for the Multiple Cause of Death field are the number of times each specific cause of death is mentioned in the record, or "any mention" of the specified cause of death. Up to 20 causes can be indicated in the Multiple Cause of Death field on any single death certificate.

Crude Rates

Crude Rates are expressed as the number of deaths reported each calendar year per the factor you select. The default factor is per 100,000 population, reporting the death rate per 100,000 persons.

Crude Rate = Count / Population * 100,000

See Frequently Asked Questions about Death Rates .

Hints:

Rates calculated with population estimates are per 100,000 persons by default. However, infant mortality rates are calculated per 1,000 live births by default. See Additional Rate Options to select the factor for rate calculations.
Select the precision for rate calculations in the Other Options section. When the rate calculated for a small numerator (incidence count) is zero, you may increase the precision to reveal the rate by showing more numbers to the right of the decimal point.

Notes:

Rates for small populations should be interpreted with caution.
Rates are suppressed for sub-national data representing zero to nine (0-9) deaths. Corresponding sub-national denominator population figures are also suppressed when the population represents fewer than 10 persons. See Assurance of Confidentiality for more information.
Rates are marked as "unreliable" when the death count is less than 20. Rates are not shown for infant age groups when the death count is less than 20, since December 12, 2011.
Rates are marked as "not applicable" when the population denominator figure is unavailable, such as persons of "not stated" or unknown age or Hispanic origin. Rates and populations are also not available for specific categories for geographic location of death's occurrence, month and week of death, place of death, whether an autopsy was performed, or any subset of ages 85 and over.
Crude rates are helpful in determining the need for services for a given population, relative to another population, regardless of size. Crude rates are influenced by the underlying age distribution of the state's population. Even if two states have the same age-adjusted rates, the state with the relatively older population (as demonstrated by having a higher median age) will have higher crude rates because incidence or death rates for most cancers increase with increasing age.
The population estimates for the denominators of incidence rates are race-specific and sex-specific population estimates. The population estimates are aggregated from the most detailed level selected, to the extent that such details for age and place are available. For example, if you have requested data for the nation grouped by state and by county, then the populations are the county-level population estimates aggregated to the state and national summaries.
The population for "Infant age groups" is the number of live births in the given time period. See Infant Mortality for more information.
About Single Race Constraints for Rate Calculations:
- Rates are only available for the list of six single race categories, because race-specific population estimates for rate denominators are only available for the list of six race categories.
- Rates and populations are not available for single-year age groups or 10-year age groups at the county level for analysis of mortality by Single Race, including analysis of Urbanization categories for counties.
- Age-adjusted rates are not available at the county level for analysis of mortality by Single Race, including analysis of Urbanization categories for counties, because the standard populations are weighted to the 10-year age groups, and county level populations estimates are not available for the "<1 year" and "1-4 years" age categories.
- See Population Denominator Data Sources below for more information.

Age-Adjusted Rates

Age-adjusted death rates are weighted averages of the age-specific death rates, where the weights represent a fixed population by age. They are used to compare relative mortality risk among groups and over time. An age-adjusted rate represents the rate that would have existed had the age-specific rates of the particular year prevailed in a population whose age distribution was the same as that of the fixed population. Age-adjusted rates should be viewed as relative indexes rather than as direct or actual measures of mortality risk.

The year "2000 U.S. standard" is the default population selection for the calculation of age-adjusted rates. However, you can select other standard populations, or select specific population criteria to determine the age distribution ratios. See Frequently Asked Questions about Death Rates for more information.

The rates of almost all causes of death vary by age. Age adjustment is a technique for "removing" the effects of age from crude rates, so as to allow meaningful comparisons across populations with different underlying age structures. For example, comparing the crude rate of heart disease in Florida to that of California is misleading, because the relatively older population in Florida will lead to a higher crude death rate, even if the age-specific rates of heart disease in Florida and California are the same. For such a comparison, age-adjusted rates are preferable. Age-adjusted rates should be viewed as relative indexes rather than as direct or actual measures of mortality risk.

The National Center for Health Statistics (NCHS) age-adjusts death rates using the direct method. That is, by applying age-specific death rates (Ri) to the U.S. standard population age distribution.

R' = S i ( Psi / Ps ) R i

where Psi is the standard population for age group i and Ps is the total U.S. standard population (all ages combined).

In the direct method, a standard age distribution is chosen and the age-specific death rates are weighted according to the standard. A reasonable choice for the standard is the U.S. total population (all races, both genders) for the year under study. To permit comparison of death rates from year to year, a standard population is used. Beginning with the 1999 data year, NCHS adopted the year 2000 projected population of the United States as the standard population. This new standard replaces the 1940 standard population that was used by NCHS for over 50 years. The new population standard affects the level of mortality and to some extent trends and group comparisons. Of particular note are the effects on race comparison of mortality. For detailed discussion, see:

Anderson RN, Rosenberg HM. Age standardization of death rates: Implementation of the year 2000 standard. National Vital Statistics Reports; vol 47 no 3. Hyattsville, Maryland. National Center for Health Statistics. 1998.

Beginning with publications of the year 2003 data, the traditional standard million population along with corresponding standard weights to six decimal places were replaced by the projected year 2000 population age distribution (see 2000 Standard Population below). The effect of the change is negligible and does not significantly affect comparability with age-adjusted rates calculated using the previous method.

Age-Adjusted Rates Hints:

Age-Adjusted Rates are optional, to select age-adjusted rates, see the Measures section in 1. Organize table layout on the Request Form. See Additional Rate Options to select populations for weighting the rates, and rate factors.
Rates are calculated per 100,000 population by default. See Additional Rate Options to select the factor for rate calculations.
Select the precision for rate calculations in the Other Options section. When the rate calculated for a small numerator (incidence count) is zero, you may increase the precision to reveal the rate by showing more numbers to the right of the decimal point.
Age-adjusted rates cannot be calculated when the data are grouped by Age Group.
Age-adjusted rates are not calculated when only one age group is selected (the effect is a ratio of one).
Age-adjusted rates are not available for "Infant age groups" because the populations for these age groups are the number of live births in the given time period, the same population denominator for each infant age group.
Standard age-adjusted rates (calculated with standard populations) are only available for Ten-Year Age Groups.
Age-adjusted rates are not available at the county level for analysis of mortality by Single Race, including analysis of Urbanization categories for counties, because the populations are weighted to the 10-year age groups, and county level populations estimates are not available for the "<1 year" and "1-4 years" age categories.

Notes:

Rates are suppressed for sub-national data representing zero to nine (0-9) deaths. Corresponding sub-national denominator population figures are also suppressed when the population represents fewer than 10 persons. See Assurance of Confidentiality for more information.
Rates are marked as "unreliable" when the death count is less than 20.
Rates are marked as "not applicable" when the denominator population figure is unavailable, such as "not stated" or unknown age or ethnicity.
Deaths of persons with "not stated" or unknown age are not included in the calculation of age-adjusted rates.
Age-specific death rates are rounded to 1 decimal place, before the weights are applied for the age distributions in the standard population. This approach matches NCHS publications, yet may be more noticeable in the precision of rates calculated for small numbers of deaths.
If a "non-standard" population is selected for age-adjusted rates, then the actual population estimates for the specified year are used to determine the specific age-distribution ratios (or weights) used in the calculation.
The following standard populations (see tables below) are options for computing age-adjusted rates:
The 2000 Standard Population is a projected population, developed before the April 1, 2000 enumerated Census occurred. For more information, see the following publications:

95% Confidence Intervals for Rates

You can request 95% confidence intervals calculated for death rates. The method for confidence intervals calculated for 100 or more deaths differs slightly from the method for confidence intervals calculated for 99 or fewer deaths.

How? Click the check box to indicate the desired measure.

Notes:

The method for confidence intervals calculated for 100 or more deaths:
The lower 95% confidence interval is the crude death rate minus (1.96 times the standard error of the rate). The upper 95% confidence interval is the crude death rate plus (1.96 times the standard error of the rate). LCI = R - 1.96 * S (R)
UCI = R + 1.96 * S (R)
The method for confidence intervals calculated for 99 or fewer deaths:
The lower 95% confidence interval is the crude death multiplied by the lower 95% confidence limit factor for a death rate based on a Poisson variable of the number of deaths. The upper 95% confidence interval is the crude death rate multiplied by the upper 95% confidence limit factor for a death rate based on a Poisson variable of the number of deaths. See Vital Statistics of the United States: Mortality, 1999: Technical Appendix Table S. LCI = R * L (0.95, D)
UCI = R * U (0.95, D)
Where:
- LCI = lower 95% confidence interval
- UCI = upper 95% confidence interval
- R = crude death rate R = (deaths / population) * 100,000
- D = the total number of deaths upon which the rate is based.
- RSE(R) = relative standard error of rate RSE(R) = 100 * square root of (1/D)
- S(R) = standard error of rate S(R) = R * (RSE(R) / 100)
- L = the lower 95% confidence limit factor for a death rate based on a Poisson variable of the number of deaths. See Vital Statistics of the United States: Mortality, 1999 Technical Appendix Table S.
- U = the upper 95% confidence limit factor for a death rate based on a Poisson variable of the number of deaths. See Vital Statistics of the United States: Mortality, 1999 Technical Appendix Table S.

  - See "Table S" for the upper and lower confidence limit factors for death rates based on a Poisson variable of the number of deaths.

Standard Errors for Rates

You can request standard errors calculated for death rates.

How? Click the check box to indicate the desired measure.

Notes:

S(R) = standard error of rate S(R) = R * (RSE(R)/100)
Where:
- R = crude death rate R = (deaths / population) * 100,000
- D = the total number of deaths upon which the rate is based.
- RSE(R) = relative standard error of rate RSE(R) = 100 * square root of (1/D)
For more information, refer to
- Age-adjusted Death Rates: Trend Data Based on the Year 2000 Standard Population
- Vital Statistics of the United States: Mortality, 1999 Technical Appendix, see the "Random Variation and Sampling Errors" section for methods.

Additional Rate Options:

Click the "+" to open this section. The options shown here vary, depending on the Measures you checked in section 1. Organize table layout on the Data Request tab. For example, to pick populations for weighting age-adjusted rates here, you must first check the box for age-adjusted rates in the Measures section.

Calculate Rates Per:		Select the factor (multiplier) for your rates. By default, all ages rates are calculated per 100,000 persons, and rates limited to infant age groups are calculated per 1,000 persons. How? See How do I select items from the list box?
Archive Rates:		Check the box if you wish to reproduce archive rates and population figures from the preceding release of these data. See Comparison with Other Releases for more information. How? See "How do I use a checkbox?"
Include age-adjusted rates?		Crude rates are reported by default. Indicate that you wish to calculate age-adjusted rates by clicking the checkbox under Measures in section 1. Organize table layout on the Data Request tab. Then choose the standard population to use for the ratios in the calculation. For more information, see: Age-Adjusted Rates and Frequently Asked Questions about Death Rates. How? See How do I use a radio button? Notes on Age-Adjusted Rates: Group your data by any variable, except for Age Groups. You are prevented from grouping the data by age groups when requesting age-adjusted rates for mortality data, because any single age group alone yields a corresponding weight of 1. Likewise, you must select more than 1 age group when requesting age-adjusted rates for mortality data. Deaths coded to the "unknown" age groups do not yield a proportional weight, as there is no corresponding population value. Select the combined age group for all persons less than 1 year of age. Age-adjusted rates are not available for deaths codes to the specific Infant Age Groups, because the representative population value for each infant age group is the (same) number of live births in selected time period.
Populations for Age-Adjusted Rates:		If you picked standard age-adjusted rates, then the list of possible standard populations used to calculate these age-adjusted rates is shown. See Age-Adjusted Rates for more information. How? See How do I select items from the list box? Note: The standard populations do not include representations of all age groups included in the mortality data. Your request criteria must combine data for the following ranges of ages: "5 - 14 years" combined and "15 - 24 years" combined.
Non-standard Age-Adjusted Rates:		If you picked non-standard age-adjusted rates, then options for selecting possible actual population criteria are shown. The actual population values for the specified year, race and location selections provide the age-specific proportional weights that calculate these age-adjusted rates. See Frequently Asked Questions about Death Rates for more information. How? See How do I select items from the list box? Type the desired Location code value into the box, one code per line. Or leave the box empty for the entire US (national population). Any region, division, state or county code shown in the Finder at Step 2 is valid. Note: If the same population is picked for your query criteria and your non-standard age-adjusted rate calculations, then the crude rates and age-adjusted rates are identical for those data rows that represent the non-standard population denominator.

Step 2. Select location:

Select the place(s) of interest. Location describes geographic areas in the United States by the location of death's occurrence or by the location of the decedent's residence.

Regions for multi-state areas;
State and County; and also
Urbanization classifies population density and other factors at the county level - choose between the 2013 or the 2006 NCHS Urban-Rural Classification Scheme for Counties.

Location

Geographic data are available by residence, or by death's occurrence. Data are available for the United States by Region, State and County, as well as by Urbanization categories for counties. Select the location(s) for the query. Any number of locations can be specified here.

How?

How?

See Location above for instructions.
See also Group Results By in Step 1.

Notes:

Data for Puerto Rico or any of the U.S. territories are not included. Therefore, data for Puerto Rico and the Virgin Islands are not included in HHS Region 2; data for Guam and American Samoa are not included in HHS Region 9.
HHS Region is based on the person's legal state of residence at the time of death.
When the data are exported, separate columns show both the label and the code for each value. To see the full list of labels and code values, request data grouped by this region for the "All" and export the results.

9	Arizona, California, Hawaii, Nevada (data for American Samoa and Guam are not included)
10	Alaska, Idaho, Oregon, Washington

State

For state level data, you can select any combination of individual states. Or group by State and leave the Location Finder selection at the default (all locations or the 50 United States and the District of Columbia).

How?

See Location above for instructions.
See also Group Results By in Step 1.

Notes:

For location of residence, the state coded represents the person's place of legal residence at the time of death.
For location of occurrence, the state coded represents the state in which the death occurred.
The states and the District of Columbia are identified by both state name and Standard Federal Information Processing (FIPS) codes in data extracts. See About FIPS Codes below.

County

County-level data are available for the United States and the District of Columbia. For county level data, you can select any combination of individual counties, or group by County. Leave the Location Finder selection at the default (all locations or the 50 United States and the District of Columbia).

How?

See Location above for instructions.
See also Group Results By in Step 1.

Notes:

For residence county, the county coded represents the person's place of legal residence at the time of death.
For occurrence county, the county coded represents the county in which the death occurred.
The counties and the District of Columbia are identified by both county name and Standard Federal Information Processing (FIPS) codes in data extracts.
About FIPS Codes: The FIPS State and county codes were established by the National Bureau of Standards, U.S. Department of Commerce in 1968. This standard set of codes provides names and codes for counties and county equivalents of the 50 States of the United States and the District of Columbia. Counties are considered to be the "first order subdivisions" of each State, regardless of their local designation (county, parish, borough, census area). Washington, D.C.; the consolidated government of Columbus City, Georgia; the independent cities of the States of Maryland, Missouri, Nevada, and Virginia; and the census areas and boroughs of Alaska are identified as county equivalents. The system is standard throughout the Federal Government. The State codes are ascending, two-digit numbers; the county codes are ascending three-digit numbers. For both the State and county codes, space has been left for new States or counties. Some changes in the FIPS codes have occurred since 1968. See Location Updates for information on how these changes affect the data.
About County Changes: Comparable total deaths and death rates may be misleading for counties with changing boundaries. See Location Updates for information on how these changes affect the data. Due to boundary changes, data are available for some counties for a limited period of time.

Urbanization

Use the radio buttons to select either the 2006 or the 2013 NCHS Urban-Rural Scheme for Counties. Select All Categories or any combination of values: Large Central Metro, Large Fringe Metro, Medium Metro, Small Metro, Micropolitan (non-metro), NonCore (non-metro). Each county is classified as one of six categories. Each death is associated with a category based on the county of the person's legal residence.

How?

Click the Radio Button above the box, to pick your preferred list.
See "How do I select items from the list box?," to limit your data to selected categories in the list.

Notes:

These categories are from the 2006 or 2013 NCHS Urban-Rural Classification Scheme for Counties.
See the NCHS Urban-Rural Classification Scheme for Counties web page for more information about the Urbanization categories.
The large central metro category contains counties in metropolitan statistical areas (MSAs) of one million or more population that have been identified by NCHS classification rules as central because they contain all or part of a principal city of the area. The large fringe metro category contains the remaining counties (similar to suburbs) in MSAs of one million or more. Counties in MSAs of 250,000 to 999,999 population are assigned to the medium metro category and counties in MSAs with populations under 250,000 are assigned to the small metro category. Nonmetropolitan counties that are designated by the Office of Management and Budget as belonging to a micropolitan statistical area are assigned to the micropolitan category and the remaining nonmetropolitan counties are assigned to the noncore category. The large central metro category is the most "urban" category and the noncore category is the most "rural" category.
To understand how the classification schemes were developed, see:
- NCHS Urban-Rural Classification Scheme for Counties
- 2013 NCHS Urban-Rural Classification Scheme for Counties
Most counties are in the same urbanization category for both the 2013 and 2006 schemes. However, for those counties whose category differs in the two schemes, some moved from a less urban to a more urban category, while others moved from a more urban category to a less urban category. For more information, see "Changes in county urbanization category: 2013 scheme versus 2006 scheme" in the report, 2013 NCHS Urban-Rural Classification Scheme for Counties.
It is recommended that the micropolitan category not be aggregated with metropolitan categories.
The Urbanization categories are identified by two columns, labels and codes, in data extracts.

Step 3. Select demographics:

Limit your data for any of the following data elements:

Age Groups - 10 year age groups, 5 year age groups, single-year ages, infant age groups
Gender - All, Female, Male
Race - select from 3 lists of Single Race categories: 6, 15 or 31 categories
Hispanic Origin - All, Hispanic or Latino, Not Hispanic or Latino, Not stated

Notes:

Rates and populations are not available for single-year and 10-year age groups at the county level, for analysis of mortality by Single Race, including analysis of Urbanization categories for counties.
Rates and populations are only available for the 6 Race list of Single Race categories.

Age Groups: 10-Year Age Groups, 5-Year Age Groups, Single-Year Ages, Infant Age Groups

First click the round radio button to show the preferred list of age groups. Then select All Ages or any combination of the individual age groups in the list box.

How?

Notes:

Rates and populations are not available for single-year age groups or 10-year age groups at the county level for analysis of mortality by Single Race, including analysis of Urbanization categories for counties.
Note that the population for the infant age groups is the number of live births in the given time period. Thus each infant age group shows the total number of live births in that period of years. For more information about infant age groups, see Mortality for Infants .
The population for the other age groups is the population estimate for each age group in the given time period. The population estimates for each year are summed together. For example, if data is requested for the age group "15 - 19 years" in the years 2000-2001, then the population estimate for this age group in the year 2000 is added to the population estimate for this age group in the year 2001. The combined population estimates for the time period are the denominator for the death rates.
Deaths of persons with "Unknown" or "Not Stated" age are included in "All" counts and rates, but are not distributed among age groups, so are not included in age-specific counts, age-specific rates or in any age-adjusted rates. See About "Not Stated" age or ethnicity for more information.
Refer to Age-Adjusted Rates for a discussion on the use of age-groups in calculating age-adjusted rates. Note that some of the age groups available in the data are not available in the standard population tables used to calculate age-adjusted rates. Deaths of persons of "Not stated" age are not included in age-adjusted rate calculations. Also, age-adjusted rates are not available for infant age groups.
Rates and Populations are reported as "Not Applicable" for any subset of ages 85 and over, because population estimates are not available for those ages.
The age groups are identified by two columns, labels and codes, in data extracts.

The following age groups are available:

10-Year Age groups:
under 1 year
1 - 4 years
5 - 14 years
10 - 14 years

Gender

Select All Genders or any combination of other values: female, male.

How? See How do I select items from the list box?.

Note: The genders are identified by two columns, labels and codes, in data extracts.

Single Race

For deaths in 2018-2019, mortality data are available by "single race" categories in three lists, with 6, 15 or 31 distinct options. Select All Races by default, or select any combination of specific categories in one of the three lists. You can only limit data or group results by one of the lists for any single query. Be sure the Radio Button is set to your choice. Pick between:

6 race categories - American Indian or Alaska Native (AIAN); Asian; Black or African American; More than one race; Native Hawaiian or Other Pacific Islander (NHOPI); White.
15 race categories - White; Black; American Indian or Alaska Native (AIAN); Asian Indian; Chinese; Filipino; Japanese; Korean; Vietnamese; Other Asian; Hawaiian; Guamanian; Samoan; Other Pacific Islander; More than one race.

How?

Click the Radio Button to the left of the box, to pick your preferred list.
Select one or more items from the list to limit your data. The default value for any list is all categories.

Notes:

Rates and population estimates are only available for the list of 6 Single Race categories.
See Race and Ethnicity Questions for more information about the issues of race categories and ethnicity in the data.
To analyze deaths in years 1999-2019 by four Bridged-race categories (American Indian or Alaskan Native, Asian / Pacific Islander, Black or African American, White), see Multiple Cause of Death 1999-2019.
The Race categories are identified by two columns, labels and codes, in data extracts.

Hispanic Origin

Select All values or any combination of other values: Hispanic or Latino, Not Hispanic or Latino, Not stated.

How? See How do I select items from the list box?.

Notes:

Population denominator data are not available for the "Not stated" category, thus rates are flagged as "not applicable."
Deaths of persons with unknown or "Not Stated" Hispanic origin are included in "All" counts and rates, but are not distributed among Hispanic Origin groups, so are not included in the Hispanic Origin specific counts and rates . See About "Not Stated" age or ethnicity for more information.
See Race and Ethnicity Questions for more information about the issues of race categories and ethnicity in the data.
The Hispanic Origin categories are identified by two columns, labels and codes, in data extracts.

Step 4. Select time period of death:

Pick between Year / Month of Death, or MMWR Year / MMWR Week of Death. Select any specific years or year/month dates to limit your data to the specified time of occurrence of death. The default value is the full range of years and months in the data collection.

How?

Pick between working with data for the selected Year / Month of Death, or the selected MMWR Year / MMWR Week of Death. Morbidity and Mortality Weekly Report (MMWR) publication years and weeks vary slightly from calendar years. MMWR Week 1 in a given year may begin after January 1st, and some years have 53 MMWR weeks, which may extend after December 31st. MMWR Weeks run Sunday through Saturday.
The first level of the Finder shows the years. Select one or more years, and then click the Open button below the list to see the months in each year.
See "How do I use a Finder?" for help.
If you prefer, You can also enter date values by hand:
1. Click the link for Advanced mode. (Advanced mode is only available when JavaScript is enabled.)
2. Use yyyy (2022) for years, yyyy/mm (2022/01) for months. Enter one date per line.
See Finder Tool help for more hints.

Notes:

Each month is considered a unique combination of year and month, such as July, 2011.
Rates and populations are shown as "Not Applicable" for months and weeks.
MMWR Week may not be combined with Year or Month.
The MMWR Year corresponds to the MMWR Week, the publication week for CDC's Morbidity and Mortality Weekly Report (MMWR) Series. The first and last MMWR Week of the MMWR Year may include dates from the preceding or next calendar year. Some MMWR Years include 53 MMWR Weeks. The MMWR Week labels lists the full week ending date (Saturday) for each week. When the date of death is unknown, the MMWR Week category is "Week Not Available."
When the data are exported, separate columns show both the label and the code for each value.

Step 5. Select autopsy and place of death :

Limit your data for any of the following data elements:

Autopsy performed: - No, Yes, Unknown
Place of Death: - Medical Facility - Inpatient, Medical Facility - Outpatient or ER, Medical Facility - Dead on Arrival, Decedent's home, Hospice Facility, Nursing home/long term care, Other, Place of death unknown.

Note that rates and populations are shown as "Not Applicable" for Autopsy and Place of Death. (Autopsy and Place of Death are not available in archive data 1999-2004 or archive data 2005-2006.)

Autopsy Performed

Select All any combination of other values for the whether an autopsy was performed: No, Yes, Unknown.

How? See "How do I select items from the list box?"

Notes:

Note that rates and populations are shown as "Not Applicable" for whether an autopsy was performed.
Data are identified by two columns, labels and codes, in data extracts.

Place of Death

Select All any combination of other values for the place of death: Medical Facility - Inpatient, Medical Facility - Outpatient or ER, Medical Facility - Dead on Arrival, Decedent's home, Hospice Facility, Nursing home/long term care, Other, Place of death unknown.

How? See "How do I select items from the list box?"

Notes:

Note that rates and populations are shown as "Not Applicable" for place of death.
The Place of Death categories changed in 2003. The "Medical Facility - Status unknown" category is only available in years 1999-2002. The "Hospice Facility" category is only available in years 2003 and later. Death counts for these categories are shown as "Missing" for those years when the data are unavailable.
Data are identified by two columns, labels and codes, in data extracts.

Step 6. Select underlying cause of death:

Select categories that represent the underlying cause of death from the death certificate. Only one underlying cause of death is indicated for each death. Deaths are coded to the International Classification of Disease Tenth Revision (ICD-10) codes. The ICD system is organized by chapters, sub-chapters and codes. Selected causes are also grouped into categories for mortality analysis. Any number of causes can be specified here. However, you can only limit data to one of the lists for any single query.

Be sure the Radio Button is set to your choice. Pick between:

ICD-10 Codes listed as chapters, sub-chapters and individual codes
ICD-10 113 Groups for selected causes of death
ICD-10 130 Groups for selected causes of infant mortality
Drug/Alcohol Induced Causes
Injury Intent and Mechanism

Hints:

Only those ICD codes that are used to classify underlying causes of death in the mortality data are available in the Finder for this section. Symptoms are not classified as underlying causes of death.
Deaths in the years 1999 and later are coded to the tenth revision of the International Classification of Diseases (ICD-10). There are 113 selected causes of death groups for the ICD-10 codes.
When you select a code, remember that some deaths are coded to the 3 length code, and not the more detailed designation. Thus some deaths may be excluded from your data selection if your criteria are limited to only 4 length codes. For example, the ICD-10 code A09 is the correct specification; A09.0 will not pick up deaths coded A09.
The causes of death are identified by two columns, labels and codes, in data extracts.

Notes:

About the International Classification of Diseases:
The mortality data are compiled in accordance with the World Health Organization (WHO) regulations, which specify that member nations classify and code causes of death in accordance with the current revision of the International Statistical Classification of Diseases and Related Health Problems (ICD). The International Classification of Diseases is developed collaboratively between the World Health Organization (WHO) and 10 international centers, for purposes of ensuring that medical terms reported on death certificates are internationally comparable and lend themselves to statistical analysis. The ICD has been revised approximately every 10 years since 1900 in order to reflect changes in understanding of disease mechanisms and in disease terminology.
See also ICD 10th revision notes.
Archive data 1999-2004 and archive data 2005-2005 select underlying cause of death in step 4 on the Request Form. Injury Intent and Mechanism, and Drug/Alcohol Induced Causes are not available in the archive data.

ICD-10 Codes

Limit the data to any number of causes of death, for selected chapters, sub-chapters or codes. The default selection is "all causes" of death.

How?

Click the Radio Button to the left of the box, to pick your preferred list.
Select one or more items from the list to limit your data. The default value for any list is all causes of death.
Hints:
- See How do use a Finder? to learn more about search options, expanding or collapsing selected items, and displaying details for selected items in the Finder.
- The "plus" symbol, "+" indicates that you can open the item, to see more items below it.
- The results to a search are shown in blue, and indicated by ">".
- The Advanced mode let you easily pick several items from different parts of the list. Items are not selected until you click the "Move" button in Advanced mode.
- You may also enter values by hand, one code per line, in the Advanced mode. Use the Finder to see the correct code format. For example, "I20-I25" is the ICD-10 code for ischemic heart diseases.
- See Finder Tool help for more hints.

Notes:

The International Classification of Disease (ICD) 10th revision is used to represent the causes of death for the years 1999 and later. The ICD system is organized by chapters, sub-chapters and codes.
ICD-10 uses a 4-length alphanumeric coding scheme. Each of the 21 chapters in ICD-10 is classified to a letter or letters of the alphabet. Infectious disease codes in Chapter 1, for example, begin with an "A" or "B". Thus, Acute poliomyelitis is associated with the codes A80.0-A80.9 and Viral hepatitis is classified as B15.0-B19.9. The ICD 10 system begins codes with a letter from the alphabet, followed by two numerals, then a decimal point to indicate subordinate position, and then more numerals. Some causes of death are represented by 3 length codes, although most causes of death are represented by 4 length codes (format A12.3). Greater detail than 4 length codes are not included in the data.
About Underlying Cause of Death:
- The underlying cause-of-death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." Underlying cause-of-death is selected from the conditions entered by the physician on the cause of death section of the death certificate. When more than one cause or condition is entered by the physician, the underlying cause is determined by the sequence of conditions on the certificate, provisions of the ICD, and associated selection rules and modifications.
- Each death certificate contains a single underlying cause of death.
- Only those ICD codes that are used to classify underlying causes of death in the mortality data are available in the Finder for selecting underlying causes of death. Symptoms are not classified as underlying causes of death.
About Multiple Cause of Death:
- Each death certificate contains up to twenty multiple causes of death.
- The ICD-10 "S" and "T" chapters are available in the Finder for selecting multiple causes of death. Symptom and "nature of injury" classifications are available for the Multiple Cause of Death field, although not available in the Underlying Cause of Death field.
- You can form Boolean "AND" queries for Multiple Causes of Death. More information.
- When data are grouped by Multiple Cause of Death, the numbers of deaths are shown attributed to each cause. However, a single person's death may have up to 20 causes on the death certificate. Thus the total number of deaths per cause may exceed the actual number of dead persons in the selected population.

About changes in ICD-10 codes:
The valid ICD-10 codes used to classify cause of death change over time, refer to table below for details. Effective with the 2019 data year, 1 code was introduced as a valid cause of death. Effective with the 2011 data year, 33 codes were introduced as valid causes of death. Effective with the 2009 data year, 5 codes were introduced as valid causes of death, and 11 codes were discontinued. Effective with the 2007 data year, 4 codes were introduced as valid causes of death, and 2 codes were discontinued. Effective with the 2006 data year, 18 codes were introduced as valid causes of death, and 4 codes were discontinued. The World Health Organization (WHO) added code I27.2 in 2003. Prior to 2003, if the certifier listed "secondary pulmonary hypertension" the condition would be coded I27.0 because there was no code for secondary pulmonary hypertension. After code I27.2 was added in 2003, the number of deaths coded to I27.0 dropped significantly.

About external causes of injury and sudden death:
In the provisional mortality data, causes of death related to external causes of injury (ICD-10 codes V01-Y89), sudden deaths (ICD-10 codes R95 and R96), or drug poisoning (ICD-10 codes T36-T50), have the cause of death labeled as "Data not shown due to 6 month lag to account for delays in death certificate completion for certain causes of death." For more information, see Technical Notes for Provisional Mortality below.
About ICD-10 cause of death codes O00-O99:
Between 2003 and 2017, states were incrementally implementing a pregnancy status checkbox which affected the comparability of data between states. In addition, evaluation of data quality indicated errors following adoption of the checkbox. Beginning with 2018 data, after all states had implemented a checkbox, NCHS restricted use of the checkbox to decedents aged 10-44 years. Additionally, for records with no indication of pregnancy except in the checkbox, the multiple cause data will only have cause of death codes O00-O99 reflecting the underlying cause. These changes are intended to mitigate probable errors. For more information, please refer to Maternal Mortality Statistics for 2018 at: https://www.cdc.gov/nchs/maternal-mortality/.
About deaths due to acts of terrorism:
Beginning with data for 2001, NCHS introduced categories *U01-*U03 for classifying and coding deaths due to acts of terrorism. The asterisks before the category codes indicate that they are not part of the International Classification of Diseases, Tenth Revision (ICD-10). Description of the specific 4-digit codes can be found at NCHS Classifications of Diseases, Functioning and Disability: Appendix I. Deaths classified to the terrorism categories are included in the categories for Assault (homicide) and Intentional self-harm (suicide) in the 113 cause-of-death list. Additional information on these new categories can be found at NCHS Classifications of Diseases, Functioning and Disability: Classification of Death and Injury Resulting from Terrorism. Terrorism related deaths in this data do not represent a final count of deaths resulting from the terrorist attacks on September 11, 2001, as this figure had not been determined. As of October 24, 2002, death certificates were issued for 2,957 of the estimated 3,028 individuals believed to have died as a result of the September 11, 2001 attacks. Of these, four were issued for terrorists and are classified as suicides. The criteria for issuing a death certificate for those believed to have died in the attacks differed by state, reflecting differences in state laws regarding death certification. Pennsylvania issued a death certificate for every individual, including the terrorists. Death certificates were not issued for any of the terrorists in Virginia or New York City. Virginia issued a death certificate only for those victims whose remains were identified. New York City issued a death certificate for those whose remains were identified or, if remains were not recovered, for those whose families applied for a death certificate. For more detailed information regarding New York City's processing of these deaths, see Deaths in World Trade Center Terrorist Attacks---New York City, 2001.

Notes:

Deaths in the years 1999 and later are coded to the tenth revision of the International Classification of Diseases (ICD-10). There are 113 selected causes of death groups for the ICD-10 codes.
NCHS has defined selected causes of death groups for analysis of mortality data: the "113 Selected Causes of Death" for all age groups, and the "130 Selected Cause of Infant Death" categorize ICD-10 codes for analysis of deaths in the years 1999 and later. The group code values are not actual ICD codes published in the International Classification of Diseases, but are "recodes" defined to support analysis by the Selected Causes of Death groups.
Group the data by "ICD-10 113 Groups" and also by "Cause of Death" to see the individual ICD codes included in each category.
A "#" symbol preceding the label indicates a "rankable" cause of death, from the National Center for Health Statistics (NCHS) list of rankable causes of death. The rankable causes are a subset of the 113 selected causes of death, and the 130 selected causes of death for infants.
Group results by "15 Leading Causes" to get death counts and rates for the top 15 rankable causes of death, for your selected query criteria. Note that cross-tabulations, zero value death counts, and suppressed values are not permitted when you group results by "15 Leading Causes." When more than one rankable cause of death occurs in the last position, all these causes are shown. The "Leading Causes of Death" and "Rankable Causes of Death" apply only to underlying causes of death. These terms are not used for analysis of contributing or multiple causes of death.

Injury Intent and Mechanism

Limit your data for any of the following data elements:

Injury Intent
Injury Mechanism & All Other Leading Causes

About the External Cause of Injury Mortality Matrix:

For the analysis of injury mortality data, all causes of death have been classified by intent and by mechanism. The causes of death that are not related to injuries have been categorized as non-injuries, and are categorized in keeping with the 113 selected causes of death groups for ICD-10. The groups of injury mechanisms are different from those based on the "113 Selected Causes of Death" for ICD-10 codes. The groupings are based on the External Cause of Injury Mortality Matrix. In addition, some non-injury groups have been combined to make for broader categories, such as Heart Disease and Tuberculosis. Note that Injury Intent and Mechanism categories are only available for underlying cause of death. Injury Intent and Mechanism categories are not available in the archive data.

For more information, see: External Cause of Injury Mortality Matrix.

In order to allow analysis of Injury Mortality across a larger span of years, the ICD-9 codes that classify the underlying cause of death for years 1979 - 1998 have been categorized to be compatible with the ICD-10 External Cause of Mortality Matrix. The categories in WONDER differ slightly from the original ICD-9 External Cause of Mortality Matrix, as follows:

ICD-9 Codes and Updated Injury Mechanism Categories
ICD-9 Code Values	Categories in the original ICD-9 External Cause Mortality Matrix	Categories compatible with the ICD-10 External Cause of Mortality Matrix
E990	Other specified and classifiable, legal intervention	Fire or hot object or substance, legal intervention
E800 - E807(.0,.1,.8,.9), E820 - E825(.0 - .5,.8,.9), E826(.2 - .8), E827 - E829(.2 - .9)	Transport, other, unintentional	Other land transport, unintentional
E846	Other specified and classifiable, unintentional	Other land transport, unintentional
E958.5	Motor Vehicle Traffic, suicide	Other land transport, suicide
E988.5	Motor Vehicle Traffic, undetermined	Other land transport, undetermined
E830 - E832	Drowning, Unintentional	Other transport, unintentional
E847 - E848	Other specified and classifiable, unintentional	Other transport, unintentional
E994	Other specified and classifiable, legal intervention	Other transport, legal intervention
E958(.3)	Natural or environmental, suicide	Other specified classifiable, suicide
E958(.6)	Transport, other, suicide	Other specified, not elsewhere classified, suicide
E988(.3)	Natural or environmental, undetermined	Other specified classifiable, undetermined
E988(.6)	Transport, other, undetermined	Other specified, not elsewhere classified, undetermined

Step 7. Select multiple cause of death

Limit the data to only those deaths that indicate the selected causes of death in the Multiple Cause of Death field. Each death certificate can include up to 20 causes of death in the Multiple Cause of Death field. The output reports the number of deaths with at least one mention of the specified causes of death, referred to as "any mentions" of deaths attributed to each cause. Choose from these classifications:

ICD-10 Codes listed as chapters, sub-chapters and individual codes
ICD-10 113 Groups for selected causes of death
ICD-10 130 Groups for selected causes of infant mortality
Drug/Alcohol Induced Causes

How?

Be sure the round radio button indicates your desired classification system. See 'How to change a radio button'.
Your selections to limit the data must go into the top most box under the "Select Records" area on the left. When the box is blank, all causes of death are the possible value.
Enter codes by hand, one per line. Or find items in the Finder Tool on the right, and then use the "Move Items Over" button in the middle to move the highlighted items from the Finder.
Note: JavaScript must be enabled for the "Move" and "Clear" buttons to work. Enter or clear codes by hand if the buttons don't work.
See 'How to use the Finder Tool' or Finder Tool Help for more information.
You can form Boolean "AND" queries for Multiple Causes of Death. More information.

Notes:

Refer to the following sections for more information on cause of death classifications:
About Multiple Cause of Death:
- Each death certificate contains up to twenty multiple causes of death.
- The ICD-10 "S" and "T" chapters are available in the Finder for selecting multiple causes of death. These "Nature of Injury" and symptom classifications are available for the Multiple Cause of Death field, although not available in the Underlying Cause of Death field.
- You can form Boolean "AND" queries for Multiple Causes of Death. More information.
- When data are grouped by Multiple Cause of Death, the numbers shown are the number of deaths with at least one mention of the specified causes of death, referred to as "any mentions" of deaths attributed to each cause. However, a single person's death may have up to 20 causes on the death certificate. Thus the total number of deaths per cause may exceed the actual number of dead persons in the selected population.
About Boolean AND queries:
- You can form Boolean "AND" queries that limit your data results to those deaths with any cause in the top box AND any cause in the lower box, such as deaths with both diabetes and nephritis on the same death certificate.
- Note that more than one ICD-10 code in the same box is treated as "this cause OR that cause."
- The "AND" condition is imposed for the join of the set of codes in the top box and the set of codes in the bottom box. For example, if the top box has codes for hypertensive renal disease (I12) and also chronic ischemic heart disease (I25], and the bottom box has codes for diabetes mellitus (E10-E14), then the results will show deaths where the record indicates both hypertensive renal disease AND diabetes mellitus occurring, and also deaths where the record indicates both chronic ischemic heart disease AND diabetes mellitus occurring at the time of death.
Note that "Select multiple cause of death" is section 5 in the Request Form in the archive data for 1999-2004 and 2005-2006.

Step 8. Other options:

Export Results:		If checked query results are exported to a local file. More information on how to import this file into other applications can be found here. How? See How do I use a checkbox?
Show Totals:		If checked totals and sub-totals will appear in the results table. How? See How do I use a checkbox?
Show Zero Values:		If checked, rows containing zero counts are included in the results table. If unchecked, zero count rows are not included. How? See How do I use a checkbox?
Precision:		Select the precision for rate calculations. When the rate calculated for a small numerator (incidence count) is zero, you may increase the precision to reveal the rate by showing more numbers to the right of the decimal point. How? See How do I select items from the list box?
Data Access Timeout:		This value specifies the maximum time to wait for the data access for a query to complete. If the data access takes too long to complete, a message will be displayed and you can increase the timeout or simplify your request. If you can't complete a request using the maximum timeout, contact user support and we will try to run a custom data request for you. How? See How do I select items from the list box?

Data Source Information

Mortality Data Sources:

The Multiple Cause of Death data are produced by the National Center for Health Statistics (NCHS) at the Centers for Disease Control and Prevention (CDC). Mortality information is collected by state registries and provided to the National Vital Statistics System. Underlying cause of death and demographic descriptors are indicated on the death certificates. Each death certificate contains a single underlying cause of death, up to twenty additional multiple causes, and demographic data. The underlying cause-of-death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." Underlying cause-of-death is selected from the conditions entered by the physician on the cause of death section of the death certificate. When more than one cause or condition is entered by the physician, the underlying cause is determined by the sequence of conditions on the certificate, provisions of the International Classification of Diseases, and associated selection rules and modifications.

Population Denominator Data Sources:

The population estimates are single-race estimates based on Bureau of the Census estimates of total U.S., State, and county resident populations. The 2018-2019 population estimates are postcensal estimates of the July 1 resident population. Note that these estimates are based on 6 single race categories: American Indian or Alaska Native (AIAN); Asian; Black or African American; More than one race; Native Hawaiian or Other Pacific Islander (NHOPI); White. The population estimates are by geographic unit (total United States, State, and county), year, race, sex, and age group. To permit the calculation of infant mortality rates, NCHS live-birth data are included on the file.

		Notes: Reporting anomalies: About cause of death classification changes: Changes to cause of death classification affect reporting trends. For more information, see Changes in ICD-10 codes. See also About ICD-10 codes O00-O99 for reporting issues affecting comparability of maternal mortality statistics. Demographic reporting: Deaths of persons with Age "Not Stated" are included in "All" counts and rates, but are not distributed among age groups, so are not included in age-specific counts, age-specific rates or in any age-adjusted rates. For more information, see Not Stated Age or Ethnicity. Information included on the death certificate about the race and Hispanic ethnicity of the decedent is reported by the funeral director as provided by an informant, often the surviving next of kin, or, in the absence of an informant, on the basis of observation. Race and ethnicity information from the census is by self-report. To the extent that race and Hispanic origin are inconsistent between these two data sources, death rates will be biased. For more information, see Race and Ethnicity Reporting.

Technical Notes for Provisional Mortality

Note: On June 6, 2022, the National Vital Statistics System (NVSS) cause of death coding system began a system-wide upgrade, which required a temporary suspension of routine NVSS surveillance reporting. The upgrade required all 2022 death records to be reprocessed into the system. As routine NVSS surveillance reporting resumes, users may temporarily observe lower death counts for prior weeks in 2022 as the backlog is reprocessed and reloaded into the system.

Comparing provisional mortality data to other sources: Provisional death counts in this report will not match counts in other sources, such as media reports or numbers from county health departments. Death data, once received and processed by National Center for Health Statistics (NCHS), are tabulated by the state or jurisdiction in which the death occurred by default.

Nature and sources of data: Provisional death counts are based on death records received and processed by NCHS as of a specified cutoff date. National provisional counts include deaths occurring within the 50 states and the District of Columbia. NCHS receives the death records from state vital registration offices through the Vital Statistics Cooperative Program. Provisional data are based on available records that meet certain data quality criteria at the time of analysis and may not include all deaths that occurred during a given time period especially for more recent periods. Estimates of completeness are provided. Therefore, they should not be considered comparable with final data and are subject to change.

Delays in reporting: Provisional counts of deaths are underestimated relative to final counts. This is due to the many steps involved in reporting death certificate data. When a death occurs, a certifier (e.g. physician, medical examiner or coroner) will complete the death certificate with the underlying cause of death and any contributing causes of death. In some cases, laboratory tests or autopsy results may be required to determine the cause of death. Completed death certificate are sent to the state vital records office and then to NCHS for cause of death coding. At NCHS, about 80% of deaths are automatically processed and coded within seconds, but 20% of deaths need to be manually coded, or coded by a person. Death certificates are typically manually coded within 7 days of receipt, although the coding delay can grow if there is a large increase in the number of deaths. As a result, underestimation of the number of deaths may be greater for certain causes of death than others.

Previous analyses of provisional data completeness from 2015 suggested that mortality data is approximately 27% complete within 2 weeks, 54% complete within 4 weeks, and at least 75% complete within 8 weeks of when the death occurred (source: Spencer MR, Ahmad F. Timeliness of death certificate data for mortality surveillance and provisional estimates. National Center for Health Statistics. 2016. Available at https://www.cdc.gov/nchs/data/vsrr/report001.pdf). Pneumonia deaths are 26% complete within 2 weeks, 52% complete within 4 weeks, and 72% complete within 8 weeks (unpublished). Data timeliness has improved in recent years, and current timeliness is likely higher than published rates.

Comparing provisional deaths from different states: Death counts should not be compared across states. Data timeliness varies by state. Some states report deaths on a daily basis, while other states report deaths weekly or monthly. Furthermore, health departments and state vital record offices may be affected by COVID-19 related response activities, which could further delay death certificate reporting. Currently, 61% of US deaths are reported within 10 days of the date of death, but there is variation within states. Twenty states report over 75% of deaths within the first 10 days, while three states report fewer than 1% of deaths within 10 days.

Deaths related to external causes of injury or sudden death: In the provisional mortality data, causes of death classified as external causes of injury (ICD-10 codes V01-Y89), sudden deaths (ICD-10 codes R95 and R96), or drug poisoning (ICD-10 codes T36-T50), have the cause of death labeled as "Data not shown due to 6 month lag to account for delays in death certificate completion for certain causes of death." For these deaths occurring 24 weeks prior to the final date in the provisional data, the number of deaths and related statistics are reported as Not Available.

Population Estimates

Population Information for the Current Release

Comparison with other releases

Population Information

The population data are single race estimates from U.S. Census Bureau files. The population estimates for year 2018 and later years are postcensal estimates of the July 1, resident population.

To permit the calculation of infant mortality rates, NCHS live-birth data are included for "Infant age Groups." The race code for these records is derived from "race of mother".

Frequently Asked Questions about Mortality

The questions are in three sections:

Questions about Death Rates

Data Release Questions

Race and Ethnicity Questions

Questions about Death Rates
1. How do I get the top 15 leading causes of death in WONDER?
  Group results by "15 Leading Causes" to get death counts and rates for the top 15 rankable causes of death, for your selected query criteria. Note that cross-tabulations, zero value death counts, and suppressed values are not permitted when you group results by "15 Leading Causes." When more than one rankable cause of death occurs in the last position, all these causes are shown.
  The "leading causes of death" published by the National Center for Health Statistics (NCHS) are also called "rankable causes of death." The rankable causes are a subset of the 113 selected causes of death, and the 130 selected causes of death for infants. A "#" symbol preceding the label indicates a "rankable" cause of death, from the National Center for Health Statistics (NCHS) list of rankable causes of death.
  The "15 leading causes of death" and the "rankable causes of death" apply only to the underlying causes of death. These concepts are not used for analysis of the contributing or multiple causes of death.
2. How are crude death rates calculated in WONDER?
  The "crude death rate" is the number of deaths divided by the population, multiplied by 100,000.
  
  Crude Death Rate = (number of deaths / population) * 100,000
  
  Note: 100,000 is the default multiplier, other multipliers can be specified in the query.
3. How are age-adjusted death rates calculated in WONDER?
  The age-adjusted rate is calculated by multiplying the age-specific death rate for each age group by the corresponding weight from the specified standard population, summing across all age groups, and then multiplying this result by 100,000 (or whatever multiplier is specified in the query).
  
  Age-Adjusted Death Rate = Sum of (Age Specific Death Rate * Standard Population weight) * 100,000
  
  The age-specific death rate is the number of deaths for a given age group divided by the population of that age group.
  
  Age Specific Death Rate = (number of deaths in age group / population of age group)
  
  The "standard population weight " for an age group is calculated by dividing the population for the age group by the sum of the populations for all of the age groups in the query. Please see the question below on "children under 1 year" age categories.
  
  Standard Population Weight = population for age group
  / sum of age group populations for all age groups in query
  
  See http://seer.cancer.gov/seerstat/tutorials/aarates/definition.html for a step-by-step tutorial with an example of the calculations.
  
  Note that the precision of the age-specific death rate is rounded to 1 decimal place, before proceeding to the next step in the calculation of age-adjusted death rates for NCHS Detailed Mortality and NCHS Multiple Cause of Death on WONDER, in order to match rates in NCHS publications. However, Compressed Mortality on WONDER does not round the age-specific death rate. Slight differences may be noted when comparing age-adjusted deaths rates. This rounding step may have a more noticeable effect on the precision of rates calculated for small numbers of deaths.
4. What are the "Standard" and "Non-Standard" populations?
  WONDER allows the user to select the population distribution used for calculating age-adjusted rates. Three "Standard" populations are offered: the year 2000 standard population (the default), the 1970 standard population, and the 1940 standard population. Alternatively, the user can specify a "Non-Standard" population for use as the population distribution in the age-adjustment.
  - The 1940 and 2000 standard populations were obtained from the National Center for Health Statistics. Beginning with the 1999 data year, NCHS adopted the year 2000 projected population of the U.S. as the standard population for use in age adjusting death rates. The year 2000 standard replaced the 1940 standard population that had been used for over 50 years. The new population standard affects levels of mortality, and to some extent, trends and group comparisons.
  - The 1970 standard population is the one used by the National Cancer Institute.
  - When the user requests that a "non-standard " population is used in the calculation of age-adjusted rates, WONDER uses the Census population estimates/counts included in the data to determine the weights used in the age-adjustment. See Population Data Description for more information.
5. What age categories are used for age-adjusted rates?
  Only age groups that fall within the age range specified in the query are used to calculate an age-adjusted rate. The "total population" for a query is the sum of the populations of each age group included in that query. For example, if an age-adjusted rate is requested for 45-74 year olds, then the total population is the sum of the 45-54 year olds, 55-64 year olds, and 65-74 year old populations. For the 1940, 1970 and 2000 standard populations, the possible age groups are:
  
  less than 1 year, 1-4, 5-14, 15-24, 25-34, ....85 years and over.
  
  If the user specifies a "non-standard" population for use in age-adjustment, then any age groups may be used.
  Note that age groups differ from the age groups used for "standard" years.
  See Age Adjustment of Death Rates for more information.
6. What about children under 1 year and rate calculation?
  When calculating mortality rates for "Infant Age Groups" (under 1 day, 1-6 days, 7-27 days, 28-264 days), the population is the number of live births in the given time period. Note that rates for infant age groups are not shown for fewer than twenty deaths, nor are race and Hispanic Origin data available, due to privacy constraints; see Assurance of Confidentiality for more information. Note that age-adjusted rates are not calculated for infant age groups, because the denominator population is the number of live births in the specified years.
  However, rates for race and Hispanic Origin are available for the age group "under 1 year of age." The "under 1 year of age" age group represents the population estimates for the given time period. For more information, see Mortality for Infants.
7. Why are death rates sometimes flagged as "Unreliable" or "Suppressed"?
  Death rates based on counts of less than twenty (death count < 20) are flagged as "Unreliable". A death rate based on fewer than 20 deaths has a relative standard error (RSE(R)) of 23 percent or more. A RES(R) of 23 percent is considered statistically unreliable.
  Death counts and death rates are "Suppressed" when the data meets the criteria for confidentiality constraints. See Assurance of Confidentiality for more information.
8. What are the "archive" rates and populations?
  "Archive" rates and population figures refer to statistics produced by preceding releases of these data. Population estimates are updated and revised over time, newer population estimates replace previous estimates. Rates calculated with revised population estimates may differ from previous figures. For more information, see Comparison with Other Releases.
Data Release Questions
1. What are the Assurance of Confidentiality constraints for vital statistics?
  All statistics representing one through nine (1-9) persons are suppressed, in the provisional mortality online database for years 2018 and later.
  Data reports for years 1989 and later must meet the NCHS data use restrictions. Vital statistics data are suppressed due to confidentiality constraints, in order to protect personal privacy. The term "Suppressed" replaces sub-national death counts, births counts, death rates and associated confidence intervals and standard errors, as well as corresponding population figures, when the figure represents one to nine (1-9) persons.
  As of December 12, 2011, additional privacy constraints apply to infant mortality statistics representing infant age groups and live births as the denominator population. When an infant mortality measure represents fewer than ten (0-9) infant deaths, all corresponding live birth population denominator figures are suppressed. When the infant mortality measure represents ten to nineteen (10-19) infant deaths, the number of deaths and live births are shown, but rates and associated measures are not shown. Race and Hispanic origin data are not available in this online database for infant age groups. However, race and Hispanic origin data are available for persons under one year of age in the other age groups, which use population estimates as population denominator data. Race and Hispanic origin detail for infant mortality statistics are available in the Linked Birth / Infant Death Records data collections.
  Totals and sub-totals are suppressed when the value falls within scope of the suppression criteria, or when the summary value includes a single suppressed figure, in order to prevent the inadvertent disclosure of suppressed values.
  The confidentiality constraints and use of the "Unreliable" flag are established by the original data providers. For more information, please contact the data providers.
  Previous privacy policies for mortality statistics shared on CDC WONDER:
  - Effective May 2023, all statistics representing one through nine (1-9) deaths are suppressed. Prior to this change, statistics representing zero deaths were suppressed.
  - As of March 23, 2022, all statistics representing zero through nine (0-9) deaths were suppressed, in the provisional mortality online database for years 2018 and later. Prior to this change, national statistics in the provisional mortality online database were not suppressed.
  - As of May 23, 2011, all sub-national mortality statistics on CDC WONDER representing zero through nine (0-9) deaths in years 1989 and later were suppressed, for regions, divisions, states and counties. Prior to May 23, 2011, data cells in tables for year 1989 and later years were suppressed only for single county-level data, when the data represented five or fewer (1-5) deaths for a time period less than three years, and the county's total population in the April 1st, 2000 Census was fewer than one hundred thousand (100,000) persons.
2. What are my responsibilities in accessing this data?
  See Data Use Restrictions to review the policies affecting access to the data. Note that use of the data implies consent or agreement to abide by the policies.
3. Why do the rates change when compared to the same time period in the archive data?
  The rates change in comparison to the archive data, because the population estimates used as the denominators in the rate calculations change. In the years following the decennial census, the Census Bureau annually produces a set of estimates containing estimates of the current year population and revised estimates of the population for previous years. Each set of estimates is referred to as a postcensal series. When the decade has passed, the population estimates for the preceding decade are revised again, producing an intercensal series of estimates. For more information, refer to the Population Data section and the section on Comparison with Other Releases.
Race and Ethnicity Questions
1. What single race categories are available for calculating rates?
  The 2018-2019 mortality data by single race calculates race-specific rates for six race categories: American Indian or Alaska Native (AIAN); Asian; Black or African American; More than one race; Native Hawaiian or Other Pacific Islander (NHOPI); White.
  To analyze deaths in years 1999-2019 by four Bridged-race categories (American Indian or Alaskan Native, Asian / Pacific Islander, Black or African American, White), see Multiple Cause of Death 1999-2019.
  For more information on calculating death rates by single race, see Single Race Constraints for Rate Calculations.
2. What ethnicity categories are available?
  The 1999-2019 mortality data has 3 Hispanic Origin categories: Hispanic or Latino, Not Hispanic or Latino, Not stated.
3. How are race and ethnicity reported?
  For more information on race and ethnicity in the mortality data, see race and ethnicity reporting.

Mortality for Infants (under 1 Year of Age)

Causes of death among persons less than one year of age vary greatly during the first year of life, and therefore special "rates" (actually, ratios) have long been used in public health to provide meaningful indicators of infant mortality. Infant mortality rates are typically calculated as the number of deaths per 1,000 live births.

Select "Infant Age Groups" for rates calculated using the number live births as the population denominator. The default multiplier for Infant Age Groups (live births population) is 1,000 births. However, the default multiplier for death rates calculated with the population estimate for persons under 1 year of age is 100,000 persons.

Three commonly used indicators of infant mortality that can be calculated in WONDER are:

Infant Mortality Rate
Number of deaths of infants (less than 1 year of age of death)
divided by the number of live births during a given period,
then multiplied by 1,000;
(Deaths of persons under 1 year of age) / Live Births) * 1000
Neonatal Mortality Rate
Number of deaths of infants less than 28 days of age
divided by the number of live births during a given period,
then multiplied by 1,000;

(Deaths of persons under 28 days of age) / Live Births) * 1000
Postneonatal Mortality Rate
Number of deaths of infants 28 days to 1 year of age
divided by the number of live births during a given period,
then multiplied by 1,000.

(Deaths of persons age 28 days to 1 year of age) / Live Births) * 1000

Note that all three indicators use the same denominator: number of live births during a given period.

To support these and other infant mortality indicators, the online database provides first-year mortality data as follows:

Infant Age Groups

less than one day old;

1 to 6 days old;

7 to 27 days old;

and 28 to 364 days old.

Hints:

Select "Infant Age Groups" for rates calculated using the number live births as the population denominator. The default multiplier for Infant Age Groups (live births population) is 1,000 births.
The single age group labeled "under 1 of age year" in the standard "Age Groups" list represents the population estimates for this age group. Death rates based on the population estimates are calculated per 100,000 persons, unless another multiplier is specified.
Change the default multiplier for the rate per number of persons in the Additional Rate Options section on the Request screen.

Notes:

Age-adjusted rates are not available for the live births population, because each infant age group uses the same population, the number of live births, to produce the age-specific rates.
Age-adjusted rates are available for the "under 1 year of age" group, when this group is combined with other age groups. Age-adjusted rates are not calculated for any single age group because the ratio is effectively "1" in this case.
The number of live births are not summed together for the population total when the data are grouped by infant age groups, because the number of live births is used as the population denominator for each infant age group.
Note that rates for infant age groups are not shown for fewer than twenty deaths, nor are race and Hispanic Origin data available, due to privacy constraints; see Assurance of Confidentiality for more information.

Location Updates: notes about specific county-level changes in boundaries and codes

Comparable total deaths and death rates may be misleading for counties with changing boundaries. The data collection may lag behind some Federal Information Processing (FIPS) location code changes. Some places, such as independent cities and New York City boroughs are included as unique locations in the data. Some county and census tract area (CA) locations are not included, instead the deaths are associated with a neighboring county or the previous location name and FIPS code. The list below of county-level changes is organized alphabetically by state name and then county name.

Alaska: Valdez-Cordova, Copper River and Chugach Census Areas
The Copper River Census Area, AK (02066) and the Chugach Census Area, AK (02063) were formed from part of former Valdez-Cordova Census Area (02261) effective January 02, 2019. Deaths are reported for the Valdez-Cordova Census Area (02261) for years 2020 and later. The population estimates for the Copper River Census Area, AK (02066) and the Chugach Census Area, AK (02063) are summed together for use as rate denominators for the Valdez-Cordova Census Area (02261) in years 2020 and later.
Connecticut: Counties and Planning Regions in 2022
Population estimates and rates are flagged as "Not Available" for the eight Connecticut counties in 2022. Deaths are reported for the eight Connecticut counties in 2022. The July 1, 2022 population estimates for Connecticut residents are available by the nine county-equivalent areas for planning regions in the 2022 postcensal series released by the Census Bureau on June 22, 2023. Population estimates for 2022 are not available for the eight counties. For more information, see the Federal Register.
Florida: Dade county and Miami city
Dade county, Florida (FIPS code 12025) was renamed Miami-Dade County and its FIPS code changed to 12086, effective November 13, 1997. The new code [12086] is used here.
Maryland: Baltimore city and Baltimore county
The independent city of Baltimore, Maryland has been treated as a county. Death counts and population estimates are reported separately for Baltimore city (FIPS code 24510) and Baltimore county (FIPS code 24005).
Missouri:
1. St. Genevieve county, Missouri
  In order to achieve alphabetical consistency, the FIPS code for St. Genevieve, Missouri was changed in 1979 from 29193 to 29186. The new code (29186) is used here.
2. St. Louis city and St. Louis county, Missouri
  The independent city of St. Louis, Missouri has been treated as a county. Death counts and population estimates are reported separately for St. Louis city (FIPS code 29510) and St. Louis county (FIPS code 29189).
Nevada: Carson City
The independent city of Carson City, Nevada (FIPS code 32510) has been treated as a county.
