    • 1980 point population coverage for the Conterminous United States

    Metadata Updated: January 7, 2026

    A point coverage was created from the 1980 Master Area Reference File (MARF) of the U.S. Census Bureay. Each point represents the center of a census tract, though some tracts were split. A 1980 population is associated with each point. Populations for 1970, 1982, 1984, and 1985 were inferred from county population data.
