  Description:
    Abstract: The Bureau of the Census Urbanized Area Boundaries data set contains boundary information for urban areas with a population greater than 50,000.  The data set 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, and size urban areas.  The data are used primarily for national planning applications.
