The Compressed Mortality database contains mortality and population counts for all U.S. counties.
Counts and rates of death can be obtained by underlying cause of death, state, county, age, race, sex, and year.
Data are also available for Hispanic ethnicity, injury intent, injury mechanism and urbanization categories
(both the 2006 and 2013 NCHS Urban-Rural Schemes are available).
This Request form allows you to request data for the years 1999 - 2015 only, with the underlying cause of death
specified with ICD-10 codes. To request data for other years, see
Compressed Mortality File.

Data Use Restrictions:
The Public Health Service Act (42 U.S.C. 242m(d)) provides that the data collected by the
National Center for Health Statistics (NCHS) may be used only for the purpose for which they were obtained;
any effort to determine the identity of any reported cases, or to use the information for any purpose other
than for health statistical reporting and analysis, is against the law. Therefore users will:
- Use these data for health statistical reporting and analysis only.
- For sub-national geography, do not present or publish death counts of 9 or fewer or
death rates based on counts of nine or fewer (in figures, graphs, maps, tables, etc.).
- Make no attempt to learn the identity of any person or establishment included in these data.
- Make no disclosure or other use of the identity of any person or establishment discovered inadvertently
and advise the NCHS Confidentiality Officer of any such discovery.
