Definition and Source



Adult population by age group.

Data presented for 2020 through 2023 are Vintage 2023 population estimates. Data presented for 2010 through 2019 are Vintage 2020 estimates. Each year the U.S. Census Bureau revises their post-2010 and post-2020 estimates. Therefore, data presented here may differ from previously published estimates. Figures for 2000, 2010, and 2020 represent revised population estimates for July 1, 2000, July 1, 2010, and July 1, 2020 - not actual Census counts from April 1, 2000, April 1, 2010, and April 1, 2020.
