The Multiple Cause of Death data available on WONDER are county-level national mortality and population data spanning the years
1999-2006. These data are available in two separate data sets: one data set for years 1999-2004 with 3 race groups,
and another data set for years 2005-2006 with 4 race groups and 3 Hispanic origin categories.
This online database contains Multiple Cause of Death data for years 2005-2006,
compiled from Multiple Cause of Death File 2005-2006 Series 20 No. 2L, 2009.
Data are based on death certificates for U.S. residents. Each death certificate contains a single underlying cause of
death, up to twenty additional multiple causes, and demographic data. The number of deaths, crude death rates or age-adjusted death
rates can be obtained by place of residence (total U.S., state, and county), age group, race, Hispanic ethnicity (years 2005-2006 only),
gender, year of death, and cause-of-death (4-digit ICD code or group of codes).
