1980 point population coverage for the Conterminous United States

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: February 10, 2026 | Last Modified: 2020-11-17T00:00:00Z
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.
