Revised Estimates of the Population of Counties by Age, Sex, and Race [United States]: 1980-1989

This data collection includes revised estimates of the population of the 3,141 counties in the United States as defined in the 1990 Census. Data are grouped by five-year age category (ages 0-4, 5-9, etc.), sex, and modified race (White, Black, other) for each year from 1980 to 1989, beginning with July 1, 1980. The revised estimates were developed by interpolating from modified Decennial Census files for both 1980 and 1990.
