Loudoun County Demographics
Both Loudoun County Government and the Census Bureau publish data and analysis about Loudoun County.  

American Community Survey (Annual Data)
The U.S. Census Bureau’s American Community Survey (ACS) provides annual demographic data including 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 rather than report actual numbers because the ACS is a survey of a small subset of the county's population. 

More ACS data can be found by going to the Census Bureau’s American FactFinder
