Bureau of the Census February 19, 2021 – Federal Register Recent Federal Regulation Documents

This notice provides the Bureau of the Census' (hereafter, Census Bureau's) proposed criteria for defining urban areas based on the results of the 2020 Decennial Census. It also provides a description of the changes from the final criteria used for the 2010 Census. The Census Bureau is requesting public comment on these proposed criteria. The Census Bureau delineates urban areas after each decennial census by applying specified criteria to decennial census and other data. Since the 1950 Census, the Census Bureau has reviewed and revised these criteria, as necessary, for each decennial census in order to improve the classification of urban areas by taking advantage of newly available data and advancements in geographic information processing technology.
