CDC WONDER mortality data
The Compressed Mortality File (CMF) is a county-level national mortality and population database spanning the years 1968-2014. Compressed Mortality data are updated annually. The number of deaths, crude death rates and age-adjusted death rates can be obtained by place of residence (total U.S., Census region, Census division, state, and county), age group, race (years 1968-1998: White, Black, and Other; years 1999-present: American Indian or Alaska Native, Asian or Pacific Islander, Black or African American, and White), Hispanic origin (years 1968-1998: not available; years 1999-present: Hispanic or Latino, not Hispanic or Latino, Not Stated), gender, year of death, underlying cause of death (years 1968-1978: 4 digit ICD-8 codes and 69 cause-of-death recode; years 1979-1998: 4-digit ICD-9 codes and 72 cause-of-death recode; years 1999-present: 4-digit ICD-10 codes and 113 cause-of-death recode), and urbanization level of residence (years 1968-1998: not available; years 1999-present: per the 2006 or the 2013 NCHS Urban-Rural Classification Scheme for Counties).
