To assess the value of medical examiner (ME) data bases for use in epidemiologic surveillance, we compared data from non-injury deaths that became ME cases to all non-injury deaths occurring in 1984 among Fulton County, Georgia residents. The decedents in the ME series were younger and included a large proportion of Black males. Although not representative of all deaths in a community, ME data bases include demographic and medical information that is often difficult to collect in community studies and in other surveillance systems.
