2020 Census: Resources and Information

FTA bases annual apportionments for transit formula funding on U.S. Census data, which the U.S. Census Bureau publishes every 10 years. The 2020 Census urban area delineations can have substantial impacts to FTA grant recipients. The effects of the new Census boundaries will be reflected in FTA’s FY 2024 apportionments. FY 2023 apportionments will be unaffected.

What’s New
