Source of data: IECAM demographers prepare population estimates based on the Census Bureau’s Population Estimates Program and the American Community Survey, 5-year estimates.

These data are available for all geographic areas on the IECAM database. On Regional Reports, all the above population data are available for all geographic regions except for ages 6 through 12.

Note: Because of pandemic-related disruptions, the U.S. Census Bureau has warned there will be somewhat larger margins of error for data collected in 2020. This will affect the 5-year American Community Survey (ACS) estimates reported on IECAM for 2020, 2021, 2022, and, when available, 2023 and 2024.
