On December 29, the U.S. Census Bureau released its new list of Urban Areas, following the 2020 Census. For more detailed information, including urban-rural classification criteria and lists of all urban areas, new urban areas, and areas previously classified as urban that are now rural, view the Census Urban and Rural web page. Also see analysis (PDF) from the Community Transportation Association of America (CTAA) on how rural and urban classification affects transit, and information from the Federal Highway Administration (FHWA) on the implications of urban area designation for regional transportation planning.
