  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.  A UA may contain both place and nonplace territory. The U.S. Census Bureau delineates UAs to provide a better separation of urban and rural territory, population, and housing in the vicinity of large places. At least 35,000 people in a UA must live in an area that is not part of a military reservation.
    Purpose: The data provide users with information about the locations, names, and size of urban areas.  The data are used primarily for national planning applications.

    Attribute_Accuracy_Report:
      The Bureau of Census supplied the attributes.
      For Census 2000, UA delineations constitute a "zero-based" approach that requires no "grandfathering" of UA boundaries from the 1990 census. Because of the more stringent density requirements (and the less restrictive extended place criteria), some territory that was classified as urbanized for the 1990 census has been reclassified as rural. In addition, some areas that were identified as UAs for the 1990 census have been reclassified as urban clusters. 

      The title of a UA may contain up to three incorporated place names, and will include the two-letter U.S. Postal Service abbreviation for each state into which the UA extends. However, if the UA does not contain an incorporated place, the UA title will include the single name of the geographic entity that occurs first from the following list: census designated place, minor civil division, or populated place recognized by the U.S. Geological Survey. 

      Each UA is assigned a five-digit census code in alphabetical sequence on a nationwide basis, interspersed with the codes for urban clusters (UCs), also in alphabetical sequence. For the 1990 census, the U.S. Census Bureau assigned a four-digit UA code based on the MA codes. For Census 2000, a separate flag is included in data tabulation files to differentiate between UAs and UCs. In printed reports, this differentiation is included in the name.

    Process_Step:
      Process_Description: Downloaded the Urbanized Areas from http://www.census.gov/geo/www/cob/ua2000.html.  Queried out Urbanized Area from the LSAD_T column and dissolved by UA.  Created the centroid of the polygon took the original NAME column and separated the column into two:  Name and State.
