The Bureau of the Census Urbanized Area Boundaries database is a geographic database of boundaries for urban areas with a population greater than 50,000. The database includes boundaries for urban areas in all 50 states, the District of Columbia, and Puerto Rico.
Purpose:
The data provide users with information about the locations, names, urban, census and FIPS Codes, and size of urban areas primarily for national planning applications.
Supplemental_Information:
Urbanized areas is an ESRI shapefile with polygon features. This is a subset of the original dataset. It has been clipped to the extent of the Long Island Sound GIS project extent.
