Data Notes

Users can generate national- or occupation-specific queries. Users can generate tables, charts and maps containing the summary statistics such as number of deaths, crude death rates, age-adjusted death rates, and years of potential life lost (YPLL). Users can also download the dataset and/or data queries into Microsoft Excel.

This website provides data history regarding revisions to the dataset. Data from additional sources (i.e., population estimates, comparative standard population, and life-table values) are also available. National mortality data is derived from the National Center for Health Statistics (NCHS) multiple cause of death records. These data are updated annually since 1968, unless otherwise indicated. Data are available on national, state, and county levels. The most recent data available is from 2007.
