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. 

On April 4, 2024, FTA announced $20.5 billion in federal funding available to support public transportation throughout the country, the latest tranche of support made possible thanks to the Bipartisan Infrastructure Law. The funding to states, urbanized areas and Tribal governments, detailed in Apportionment Tables, is based on statutory formulas. There are two changes in Fiscal Year (FY) 2024 that impact apportionment amounts.

• FY24 apportionments reflect the U.S. Census Bureau’s new urbanized area boundaries and population figures released in December 2022. See Summary of FY24 Apportionment Changes and FY2024 Apportionments Webinar Presentation and Recording.
• FTA used transit agencies’ most recent service numbers (2022) reported to the National Transit Database (NTD) to calculate apportionments.
