Population by County, Age, Race and Gender. Population estimates are produced annually by the State Demography Office. These tables are estimates of the population’s age, sex, race and ethnic distribution by county for the years beginning in 2000 through the most recent estimate year. These data are based on distributions from the 2000 and 2010 Census of age, sex, race and ethnicity and the most recent CDC estimates by race/ethnicity. These estimates are provided by detailed age, race and ethnic group and users of the single-year-of-age county-level bridged race population estimates should consider aggregating age/race/ethnic group to improve reliability. Please contact Cindy DeGroen with any questions regarding the estimates or the bridging methods.
