Where does WISQARS get its data?
Death data come from a national mortality database compiled by CDC’s National Center for Health Statistics. This database contains information from death certificates filed in state vital-statistics offices and includes causes of death reported by attending physicians, medical examiners, and coroners. It also includes demographic information about decedents reported by funeral directors, who obtain that information from family members and other informants. Population data come from the Bureau of the Census. These data are based on information gathered in censuses and on estimation procedures conducted in non-census years.
