Historical County Estimate Files: Population Estimates of the United States, States and Counties, 1980-1989 (ICPSR 25362)

Principal Investigator(s):


The intercensal formula for the 1980s is described in Current Population Reports, Series P25-1106. The formula was applied to both state and county estimates. The intercensal estimates are based on census counts which include the latest corrections available at the time of production. The methodology for the 1980s postcensal estimates estimates is described in P26-88A, and in several technical papers emanating from the Population Estimates Branch.

Additional information can be found on the U. S. Census Bureau Population Estimates Website.
