National Vital Statistics System (NVSS) mortality data include demographic, geographic, and cause-of-death information on decedents including place of birth, place of death, educational attainment, marital status, race, and tobacco use. The data follows the International Classification of Disease (ICD) rules established by the World Health Organization.

Researchers may request custom microdata (birth, death, fetal death, and linked birth/infant death) containing geographic detail for all states and counties.
