Title: How National Urbanization Trends Will Affect Rural Transit Funding and “Trending Urban” Transit Systems in Georgia and the Nation after the 2020 Census


In the U.S., there are two main sources of transit funding administered by the Federal Transit Administration (FTA). The amount of FTA funding a transit agency receives depends, in part, on whether the agency serves an area that is designated as rural, small urban, or large urban. These designations are defined using the most recent decennial census. Between 2000 and 2010, the percentage of the U.S. population residing in urban areas increased by over 12%. Population forecasts suggest these trends will continue and will be reflected in the 2020 decennial census. In this presentation, we examine how spatial and temporal changes in the U.S. population will impact funding for transit systems in the U.S. after the 2020 decennial census. We use binary logic models and geographic information system (GIS) methods to predict spatial and temporal population changes between 2010 and 2020 and identify which areas of the U.S. will be classified as rural, small urban, or large urban after 2020. We then use this information to forecast funding requirements for the FTA § 5311 and FTA § 5307 programs after the 2020 decennial census and to identify rural areas that could become enveloped into large areas after the 2020 decennial census. The latter is important because rural transit agencies that shift to large urban areas after the 2020 decennial census will lose their ability to use federal funding for operating expenses for two years due to the “100 bus rule.” Results show that amount of additional funding needed for the FTA § 5307 small urban will be $344M–$411M, representing a 28%–33% increase over current levels.
