CDC Wonder is a massive database that compiles detailed mortality data from every county and state in America. Each cause of death is recorded as an ICD-10 code (International Cause of Death) for consistency.

For a given cause of death, CDC Wonder reports the data as raw numbers, a crude rate, or an age-adjusted rate. Data may also be reported as the underlying cause of death, or one of multiple causes of death.

  • Includes both underlying causes of death (UCD) and multiple causes of death (MCD), with age-adjusted and crude rates.
  • Data granularity: national, state, and counties, broken down by sex, age, race, and ethnicity.
  • Timeframe: annual data, ranging from 1999 to 2016.
