Name | Population Estimates of All Areas by Age, Race, & Gender |
Summary | Population by age, race, and gender for states, counties, cities, ZIP Codes, and Census Tracts |
Additional Background |
This database provides population estimates by age, race, and gender for states, counties, cities, ZIP Code Tabulation Areas (ZCTAs) (which we call ZIP Codes), and Census Tracts. Population data are based on 5-year American Community Survey (ACS) estimates, which are described in detail here. 5-year ACS estimates reflect a five-year data collection period. For example, the year 2023 represents the 5 calendar years ending 2023, i.e., from January 2019 through December 2023). These 5-year estimates have larger samples and smaller margins of error than 1-year estimates, but they are less current because the larger samples include data that were collected in earlier years. Another advantage of 5-year estimates is that these include all areas, including those with less than 65,000 population, which are not included in 1-year ACS surveys.
Data for ZCTAs reflect geographic areas created by the U.S. Census Bureau to represent the approximate area covered by a ZIP Code. ZCTAs roughly corresponds to a ZIP Code's geographic region but are not exact matches. For additional information on ZCTAs, see here.
