Demographic Characteristics
Loudoun County Demographics
The Department of Planning and Zoning performs and publishes analysis of Loudoun County demographic characteristics and issues. In addition, the Census Bureau publishes data on Loudoun County. 
American Community Survey (Annual Data)
The U.S. Census Bureau’s American Community Survey (ACS) has been providing data that describes Loudoun County starting with 2005, and has taken the place of the “long form” data gathered with the decennial census through 2000.  The ACS is a source for descriptive statistics for 2010 as well as for intercensal year data.  Available statistics include such things as educational attainment, foreign born population, language spoken at home, household income, and housing characteristics.

When using the American Community Survey’s data, it is best to use percentages from the ACS, rather than report actual numbers. Since the ACS is a survey, it is not meant to be used as a count of population and households.  ACS one-year estimates are best to use if current data is needed, but they can have large statistical sample error.  ACS five-year estimates are best to use for increased statistical reliability. Three-year data are also available. 

Loudoun County analyses using ACS demographic data are provided below, as well as U.S. Census Bureau demographic profile data sheets.  More ACS data can be found by going to the Census Bureau’s American FactFinder
