    Description:
      Abstract:
        This map is an ARC/INFO coverage of all counties within the mid-Atlantic region (SFR 3).  Attributes within the coverage contain U.S. Census data on population for both 1970 and 1990.

      Purpose:
        These data were created as part of a regional assessment of landscape conditions
         in the mid-Atlantic region (SFR 3) (Jones et al., 1997).

Process_Step:
        Process_Description:  
	Ascii file data were downloaded from the Census web site (currently http://www.census.gov/population/www/censusdata/pop-hc.html).  This population information was then imported into ARC/INFO, and joined to a polygon coverage of county boundaries.  The counties were from ESRI's ARC/USA database.
