Abstract:

This GIS layer contains the geographical boundaries of the 2010 Census Designated Places (CDP) for Loudoun County, Virginia. CDPs are delineated to provide data for concentrations of population in unincorporated communities that are well-known, distinct, closely settled, and identifiable by name and have a mix of residential, commercial, and retail or will soon have a mix.

This 2010 CDP GIS layer's boundaries are based on the U.S. Census Bureau Census 2010 TIGER/Line files. The boundaries are an extract of aerial photography and cartographic information, such as roads and streams, from the Loudoun County GIS system. CDP's are bounded on all sides by visible features, such as roads, streams, lakes, power lines, and railroad tracks, and/or by non-visible boundaries such as town, county, and neighborhood subdivision boundaries, and short line-of-sight extensions of streets and roads.

Purpose:

Census Designated Places (CDP) are used in demographic analyses. CDPs are used to gain a detailed picture of population, housing, economic, and other demographic characteristics within unincorporated communities that are well-known, distinct, closely settled, and identifiable by name and have a mix of residential, commercial, and retail or will soon have a mix.

Supplemental Information:

Loudoun County's Census Designated Places (CDP) were delineated by Loudoun County Government during the Census Bureau's Participant Statistical Areas Program for the 2010 Census.

The 2010 Census CDP layer has been modified from the Census Bureau's Tiger line file. Users should be aware that the Census's Tiger line data is devised from a mix of national and local GIS data sets. When the Tiger line data is overlaid with Loudoun County Government's detailed GIS layers it can be determined that the Census Bureau's Tiger line boundaries in some cases are slightly off from the actual location of the physical features, natural features, and governmental units such as town boundaries that they are designated to follow. The 2010 Loudoun CDP layer was generated by Loudoun County so that the CDP boundaries would overlay with the features in Loudoun County's GIS data sets that the boundary are designated to follow.
