Type of File
Microdata; unit of observation is individuals, families, and households.
Universe Description
The universe is the civilian noninstitutional population of the United
States living in housing units and members of the Armed Forces living in
civilian housing units on a military base or in a household not on a
military base. A probability sample is used in selecting housing units.
Subject-Matter Description
This file, also known as the Annual Demographic File, provides the usual
monthly labor force data, but in addition, provides supplemental data on
work experience, income, noncash benefits, and migration. Comprehensive
work experience information is given on the employment status, occupation,
and industry of persons 15+ years old and over. Additional data for
persons 15 years old and older are available concerning weeks worked
and hours per week worked, reason not working full time, total income and
income components, and residence on March 1, 1990. Data on employment and
income refer to the preceding year, although demographic data refer to the
time of the survey.
This file also contains data covering nine noncash income sources: food
stamps, school lunch program, employer-provided group health insurance
plan, employer-provided pension plan, personal health insurance, Medicaid,
Medicare, CHAMPUS or military health care, and energy assistance.
Characteristics such as age, sex, race, household relationship, and
Spanish origin are shown for each person in the household enumerated.
Geographic Coverage
State of residence is uniquely identified as well as census geographic
division and region. The 113 largest metropolitan statistical areas
(CMSAs or MSAs), an additional 89 selected MSAs, 66 selected PMSAs, and
30 central cities in multi-central city MSAs or PMSAs are also uniquely
identified.(1) Within confidentiality restrictions, indicators are
provided for MSA-PMSA/non-MSA-PMSA, central city/noncentral city, farm/
nonfarm, and MSA/CMSA size.

Related Machine-Readable Data Files
A public use edition of the Current Population Survey, March file is
available for each year since 1968. For 1980, 1984, and 1988 two March
files are available for each year. The first March 1980 file contains
estimates based on 1970 population counts and should be used for
historical comparisons ending in 1980. The reweighted March 1980 file
contains estimates based on results of the 1980 census and should be used
for comparisons between 1981 and 1984.
In 1984, the Bureau of the Census introduced a step into the March second
stage weighting procedure controlling individual weights to independent
estimates of the Hispanic population. Since this introduction caused a
major disruption in the Hispanic estimates from March two data files were
created. The first file, without the Hispanic controls should be used for
comparing estimates for years prior to 1984 and the second file should be
used for comparison with 1985 and forward files.
From March 1989 forward, data on the Annual Demographic File are processed
using the rewrite system. The rewrite system includes revised procedures
to match supplement records to basic CPS records; revised weighting
procedures; revised demographic and family edits; revised imputation
procedures; and more income detail on the file.
For March 1988 there are two files, the regular Annual Demographic File
and the Annual Demographic Rewrite File. The rewrite file has been
prepared to allow historical comparison of data from the rewrite
processing system implemented between 1988 and 1989. It is recommended
that the rewrite file be used when comparing data collected from the March
Annual Demographic Supplement from 1988 forward. Use the regular file,
released in 1988, when comparing data from 1988 and prior years.
This is not to say, however, that comparisons cannot be made between years
before and after 1988. When such analyses are done, for example between
1986 through 1989, data users must consider that similarities or
differences between the data may be caused or effected by the rewritten
system. Thus, comparing estimates from the 1988 rewrite files and the
1988 regular file will reveal the extent of any differences caused by the
processing system changes though not the specific change. The magnitude of
the difference can then be applied to the estimates from 1986-1987 to
reveal whether any real differences exist. There were several revisions
made to the processing programs; therefore, it is difficult to determine
which specific revision effected the differences or similarities in the
data.
Some non-March data also are available from 1968 to present. For more
information, request the Data Developments on the Current Population
Survey from Data User Services Division, Customer Services, Bureau of the
Census, Washington, DC 20233.

OVERVIEW
Introduction
The Current Population Survey (CPS) is the source of the official Government
statistics on employment and unemployment. The CPS has been conducted monthly
for over 40 years. Currently, we interview about 57,000 households monthly,
scientifically selected on the basis of area of residence to represent the
Nation as a whole, individual States, and other specified areas. Each
household is interviewed once a month for four consecutive months one year,
and again for the corresponding time period a year later. This technique
enables us to obtain month-to-month and year-to-year comparisons at a reason-
able cost while minimizing the inconvenience to any one household.
Although the main purpose of the survey is to collect information on the
employment situation, a very important secondary purpose is to collect
information on the demographic status of the population, information such as
age, sex, race, marital status, educational attainment, and family structure.
From time to time additional questions are included on such important
subjects as health, education, income, and previous work experience. The
statistics resulting from these questions serve to update similar information
collected once every 10 years through the decennial census, and are used by
Government policymakers and legislators as important indicators of our
Nation's economic situation and for planning and evaluating many Government
programs.
The CPS provides current estimates of the economic status and activities of
the population of the United States. Because it is not possible to develop
one or two overall figures (such as the number of unemployed) that would
adequately describe the whole complex of labor market phenomena, the CPS is
designed to provide a large amount of detailed and supplementary data. Such
data are made available to meet a wide variety of needs on the part of users
of labor market information.
Thus, the CPS is the only source of monthly estimates of total employment
(both farm and non-farm); nonfarm self-employed persons, domestics, and
unpaid workers in nonfarm family enterprises; wage and salary employees; and,
finally, estimates of total unemployment.
It provides the only available distribution of workers by the number of hours
worked (as distinguished from aggregate or average hours for an industry),
permitting separate analyses of part-time workers, workers on overtime, etc.
The survey is also the only comprehensive current source of information on
the occupation of workers and the industries in which they work. Information
is available from the survey not only for persons currently in the labor
force but also for those who are outside the labor force. The characteristics
of such persons - whether married women with or without young children,
disabled persons, students, older retired workers, etc., can be determined.
Information on their current desire for work, their past work experience, and
their intentions as to job seeking are also available.
The March CPS, also known as the Annual Demographic File, contains the basic
monthly demographic and labor force data described above, plus additional
data on work experience, income, noncash benefits, and migration.
CPS Sample
The CPS sample is based on the civilian noninstitutional population of the
United States. The sample is located in 729 sample areas comprising 1,973
counties and independent cities with coverage in every State and in the
District of Columbia.
In all, some 71,000 housing units or other living quarters are assigned for
interview each month; about 57,000 of them containing approximately 114,500
persons 15 years old and over are interviewed. Also included are demographic
data for approximately 33,500 children 0-14 years old and 650 Armed Forces
members living with civilians either on or off base within these households.
The remainder of the assigned housing units are found to be vacant, converted
to nonresidential use, contain persons with residence elsewhere, or are not
interviewed because the residents are not found at home after repeated calls,
are temporarily absent, or are unavailable for other reasons. Approximately
14,000 noninterview households are present each month. The resulting file
size is approximately 163,000 records. In March of each year supplemental
data are collected for Armed Forces members residing with their families in
civilian housing units or on a military base. The Armed Forces members,
however, are not asked the monthly labor force questions. In addition, the
March CPS is supplemented with a sample of Spanish households identified the
previous November. This results in the addition of about 2,500 households in
the March CPS. The inclusion of the additional sample of Spanish households
began in 1976.
A more precise explanation regarding the CPS sample design is provided in
Technical Paper 40, The Current Population Survey Design and Methodology.
For a more detailed discussion about the basic labor force data gathered on
a monthly basis in the CPS survey, see the Bureau of Labor Statistics
Report No. 463 and the Current Population Report P-23, No. 62, issued jointly
by the Bureau of Labor Statistics and the Bureau of the Census in October,
1976, and entitled Concepts and Methods Used In Labor Statistics derived from
the Current Population Survey.
Revisions To The March CPS Processing System
Introduction. Between 1988 and 1989 a new computer processing system was
introduced for the March Current Population Survey. This processing system
rewrite was long overdue; the system in use before this year was first
introduced in March 1976 and was never fully updated to reflect the numerous
questionnaire changes that have taken place since that time. In addition, the
programs used to process the CPS file were written in a computer language
that is being phased out of use at the Census Bureau. While the March 1989
file is the first to reflect this new processing system, the March 1988 file
was reprocessed based on these new procedures in order to: 1) better evaluate
the new processing procedures, and 2) allow year-to-year comparisons to be
made between income years 1987 and 1988 using a consistent processing system.
While the following section deals mainly with modifications to the March
imputation procedures and their subsequent effect on income and poverty
rates, it should be pointed out that all of the processing programs were
rewritten in 1989, so that not only are the files from 1989 forward based on
a somewhat different imputation system, but also reflect a rewritten
weighting system, data acceptance program, family relationship edits, and new
procedures to match income supplement records to the monthly CPS file. As a
result, it is difficult to ascertain whether differences (especially those
based on relatively small bases) are the result of imputation or other
processing differences between the original and revised files.
Since the Census Bureau began imputing the missing income data on the CPS in
1962, there have been three major revisions to the processing system (in
1967,1976, and 1989). Through all of these revisions, the basic strategy used
in make imputations has remained the same. This approach, commonly referred
to as "hot deck" imputation, assigns missing responses to sample persons with
information from matched sample persons with similar demographic and economic
information who answered these questions.
Under the new March processing system, there were three main modifications to
the income imputation programs:
1. The edits and imputations were expanded to reflect the full detail of
the March income questionnaire. The original processing system was
still based on a less detailed CPS income questionnaire that has not
been in use since 1980.
2. Under the revised processing procedures, entire sets of March income
and noncash benefits data were imputed to supplement noninterviews
from the same interviewed person. Under the original processing
procedures, earnings, unearned income, and noncash benefits were
imputed in separate stages during the processing system. Thus, the
new processing system imputes noninterviews more efficiently and is
better able to preserve the correlation between earnings, unearned
income, and noncash benefits.
3. Both the old and new processing systems employ what are called
"statisticial matches" to link sample cases with reported data to
those requiring imputation for missing responses. In the original
processing system, under certain circumstances, reported data was
removed and replaced with imputed data during the statistical matching
process. Under the new system, reported data are never removed. This
was accomplished by expanding the number of statisticial matches
in the income imputation system.
File Structure
There is a household record for each household or group quarters. The
household record is followed by one of three possible structures:
A.If the household contains related persons and is not a group
quarters household:
1. The family record appears next followed by person records for
members of the family who are not also members of a related
subfamily. The person records would be ordered: family householder,
spouse of family householder, children in the family, and other
relatives of the family householder.
2. The above records may be followed by one or more related subfamily
records, each related subfamily record being followed immediately
by person records for members of that related subfamily. The person
records would be ordered: reference person of the related subfamily,
spouse of subfamily reference person, and children of subfamily
reference person.
3. The above records may be followed by one or more unrelated subfamily
records, each unrelated subfamily record being followed immediately
by person records for members of that unrelated subfamily. The
person records would be ordered: unrelated subfamily reference
person, spouse of subfamily reference person, and children of
subfamily-reference person.
4. The above records may be followed by one or more persons living
with nonrelatives family records, each to be followed by the person
record for the unrelated individual it represents. (See Figure 1,
page 2-4.)
B.If the household contains a householder with no relatives and is not a
group quarters household:
1. The family record for the nonfamily householder is followed
immediately by the person record for that nonfamily householder.
2. These records may be followed by one or more unrelated subfamily
records, each unrelated subfamily record being followed immediately
by the person records for members of that unrelated subfamily.
3. These records may be followed by one or more family records for
persons living with nonrelatives, each person living with
nonrelatives family record being followed immediately by the
person record for that person living with nonrelatives. (See Figure
2, page 2-5.)
C.If the household is a group quarters, each person is defined as a
person living with nonrelatives. There will be a family record followed
by a person record for each person in the group quarters.
Relationship of Current Population Survey Files to Publications
Each month, a significant amount of information about the labor force is
published by the Bureau of Labor Statistics in the Employment and Earnings
and Monthly Labor Review Reports.
As mentioned previously, the CPS also serves as a vehicle for supplemental
inquiries on subjects other than employment which are periodically
added to the questionnaire. From the basic and supplemental data the Bureau
of the Census issues four series of publications under the general title
Current Population Reports:
P-20 Population Characteristics
P-23 Special Studies
P-27 Farm Population
P-60 Consumer Income
Of particular interest to users of the March microdata file would be those
reports based on information collected in March. These reports include the
following titles:
P-20 Population Profile of the United States: (Year)
P-20 Household and Family Characteristics: March (Year)
P-20 Households, Families, Marital Status, and Living Arrangements:
March (Year)
P-20 Geographical Mobility (Years)
P-20 Educational Attainment in the United States (Years)
P-20 Persons of Spanish Origin in the United States (Year)
P-60 Money Income and Poverty Status of Families and Persons in the
United States: (Year)
P-60 Characteristics of the Population Below the Poverty Level: (Year)

Geographic Limitations
In July 1985, the CPS microdata files began carrying the metropolitan
statistical area definitions announced by the Office of Management and Budget
on June 30, 1984. The new CPS estimates for the total metropolitan population
have consistently been higher than independent estimates of the total
metropolitan population prepared by the Census Bureau; the new CPS
nonmetropolitan estimates have been lower than the independent estimates. The
magnitude of the monthly differences has varied from 900,000 to 2.5 million
persons over the past year, so that the proportion of the population living
in metropolitan areas according to the CPS has ranged from 0.4 to 1.0
percentage points higher than the independent estimate. The difference in
level between the two sets of estimates is partially attributable to the
basic CPS sample design, which, because of sampling variability, includes an
oversample of metropolitan households and an undersample of nonmetropolitan
households. The monthly variations result from the exit and entrance of
rotation groups, each with slightly different metropolitan-nonmetropolitan
proportions, into the sample. The apparent overestimation of metropolitan
and underestimation of nonmetropolitan population in the CPS relative to the
Census Bureau's independent estimates should be taken into account when using
the data. Because of the monthly variation in these estimates, month-to-month
comparisons of metropolitan and nonmetropolitan estimates should be
interpreted with caution.
One other set of estimates that can be produced from CPS microdata files
beginning in October 1985 should be treated with caution. These are estimates
for individual metropolitan areas. The change in Census Bureau confidential-
ity rules allowing identification of areas with populations of 100,000 or
more instead of 250,000 has produced a situation where we now identity
numerous small metropolitan areas on the CPS data files. Although estimates
for the larger areas such as New York, Los Angeles, and so forth, should be
fairly accurate and valid for a multitude of uses, estimates for the smaller
metropolitan areas (those with populations under 500,000) should be used with
caution because of the relatively large sampling variability associated with
these estimates.
It should be kept in mind that the sample design and methods of weighting
CPS data are geared towards producing estimates for the entire Nation.
Consequently, data for states are not as reliable as national data, and the
file will lose some of its utility in certain applications. For further
discussion of such considerations, the user should consult The Current
Population Survey: Design and Methodology (Technical Paper 40, U.S. Bureau of
the Census).
The nature of the work done by each individual investigator using the
microdata file will determine to what extent his/her requirements for
precision will allow using some of the smaller geographic areas identified
on the file.
2Weights
For all CPS data files a single weight is prepared and used to compute the
monthly labor force status estimates. An additional weight was prepared for
the earnings universe which roughly corresponds to wage and salary workers in
the two outgoing rotations. This is explained below in the section on
earnings data. However, the difference in content of the March CPS supplement
requires the presentation of additional weights: a household weight, a family
weight, and a March supplement weight. In this section we briefly describe
the construction and use of these weights. Chapter 5 of Technical paper 40,
The Current Population Survey: Design and Methodology provides documentation
of the weighting procedures for the CPS both with and without supplement
questions.
The final weight, which is the product of several adjustments, is used to
produce population estimates for the various items covered in the regular
monthly CPS. This weight is constructed from the basic weight for each
person, which represents the probability of selection for the survey. The
basic weight is adjusted for special sampling situations and failure to
obtain interviews from eligible households (noninterview adjustment). A two-
stage ratio estimation procedure adjusts the sample population to the known
distribution of the entire population. This two-stage ratio estimation
process produces factors which are applied to the basic weight (after the
special weighting and noninterview adjustments are made) and results in the
final weight associated with each record. In summary, the final weight is the
product of: (I) the basic weight, (2) adjustments for special weighting,
(3) noninterview adjustment, (4) first stage ratio adjustment factor, and
(5) second stage ratio adjustment factor. This final weight should be used
when producing estimates from the basic CPS data.
Differences in the questionnaire, sample and data uses for the March CPS
supplement result in the need for additional adjustment procedures to
produce what is called the March supplement weight. The sample for the March
CPS supplement is expanded to include male members of the Armed Forces who
are living in civilian housing or with the family on a military base, as
well as additional Spanish households which are not included in the monthly
labor force estimates.
The expanded sample and the need to have a husband and wife receive the same
weight has resulted in a weighting system which produces the March supplement
weight. The March supplement weight should be used for producing estimates
from March supplement data.
Finally, household and family weights are the weights assigned from the
householder or reference person after all adjustments have been made and
should be used when tabulating estimates of families-households.
Earnings Data
Beginning in 1982, usual hourly and weekly earnings data appear on the Annual
Demographic File (ADF) for that portion of the population roughly correspond-
ing to wage and salary workers (self-employed persons in incorporated
businesses are excluded, although they are normally included with the wage
and salary population). These data are now collected on a monthly basis in
the two outgoing rotation groups as part of the basic CPS labor force
interview.
Since the intent of the regular collection of earnings data was to initiate
a family earnings data series, all persons in the two outgoing rotations
receive an "earnings weight," even if they are not eligible for the earnings
item. The earnings weight is a simple ratio-estimation to the person's labor
force status by age, race, and sex. When tabulating estimates of earnings
based on basic CPS data, use the earnings weight.
Further information on this earnings series is contained in Technical
Description of the Quaterly Data on Weekly Earnings from the Current
Population Survey, BLS Report #601, July 1980. This report is available on
request from the U.S. Department of Labor, Bureau of Labor Statistics,
Washington, D.C. 20212. Attn: Office of Inquiries and Correspondence.
NOTE: For 1982 and 1983, usual weekly earnings are not present for
individuals who were not paid on an hourly basis.
MATCHING OF MARCH CPS FILES
General Information
There are two basic limitations in linking the March CPS files across years.
First, only fifty percent of the sample is included in two consecutive years.
Second, the residents within the eligible housing units may have changed or
appeared as noninterview records in one or both years. The result is a
matched sample of considerably less than the upper limit of fifty percent.
The basic procedures and variables used to link two or more March CPS files
are outlined below.
Sample Selection
The first step in matching year t with year t+1 is to select from year t
those housing units with a "month in sample" value of 1 through 4, and from
year t + 1 those units with a "month in sample" value of 5 through 8. This
will identity the sample subset eligible for matching. Within this subset,
housing units in year t, month 1 will match only with units in year t+ 1,
month 5, etc.
Matching Housing Units
Using one or more variables, it is possible to uniquely identify each housing
unit in each sample rotation. However, because of changes in CPS procedures,
the available information for matching housing units is not always identical.
Below are the variables available for matching March CPS files.
Years: 1968-1971
Variables: Random Cluster Code (F6- 10) and Serial Number (F11-14)
Years: 1971-1972
Changes in CPS clustering procedures and the accompanying change
of household identification numbers prevent matching 1971 and
1972 March CPS files.
Years: 1972-1973
The 1972 file uses 1960 random cluster codes while the 1973 file
uses 1970 random cluster codes, thus precluding the matching of
records.
Years: 1973-1975
Variables: Random Cluster Code (F7-11). Segment Number (F12-16), and Serial
Number (F217-218)
Years: 1975-1976
Variables: 1975: Random Cluster Code (F7-11) Segment Number (F12-16), and
Serial Number (F217-218)
1976: Random Cluster Code (H35-39), Segment Number (H40-43), and
Serial Number (H44-45)
Years: 1976-1977
Matching is not possible because variables required for matching
are in a different format each year.
Years: 1977-1985
Variable: Household Identification Number (H18-29)
Years: 1985-1986
Matching is not possible because the 1986 file is based entirely
on the 1980 census design sample.
Years: 1986 Forward
Variable: Household Identification Number (H18-29)
Matching Households, Families, and Persons
Although the information presented above allows matching of housing units
across years, it is possible that the residents of the housing unit have
changed. Consequently, it is necessary to perform additional matches to
insure resident comparability. The specific variables used to match residents
will vary according to the needs of the project but it is more efficient to
arrange the matching in a hierarchical sequence. For example, matching on
sex and race should precede matching on age or household relationship. The
user should carefully work through the possible changes in household
structure that might result in an inappropriate rejection of a household.
For example, a husband-wife family in year t that experienced a divorce and
became a female headed household in year t+ 1 would fail the test for
matching sex of head. Clearly, the more criteria used in matching records
will result in greater accuracy, but will also increase the expense and
result in fewer matches.
HOW TO USE THE DATA DICTIONARY
The Data Dictionary describes the contents and record layout of the public-

HHTYPE" or "HFIN-YN", or a sequential
identifier such as "MIG-MTR1" or "SUR-
SC1". Data item names are unique through-
out the entire file (all 3 record types).

decimal places is provided in notes.
Begin. Numeric. Contains the location in the
data record of the first character position of
the data item field.
Category Value. Numeric. Contains the
range of values for the given data item.
The first line of each data item description begins with the character "D"
(left-justified, two characters). The "D" flag indicates lines in the data
dictionary containing the name, size, and begin position of each data item.
This information (in machine-readable form) can be used to help access
the data file. The line beginning with the character "U" describes the
universe for that item. Lines containing categorical value codes and labels
follow next and begin with the character "V". The special character (.)
denotes the start of the value labels. Two examples of data item descriptions
follow:

How to Distinguish Supplement Variables from Monthly Variables
Monthly variables have a prefix and trailer as follows:
1. H-, HG-, or H% for household record variables.
2. A-, A% for person record variables.
3. The family record contains no monthly variables.
Supplement variables are all one string or they have a suffix. For example
HFIN-YN is a supplement variable on the household record.
