Private contractors based in Arlington, Va, earned more than $818 million or 29.5 percent of all Department of Homeland Security contracts during 2004, capturing a greater amount of homeland security dollars than any other single jurisdiction in the United States. This was the finding of a study conducted by Heike Mayer, assistant professor in the Department of Urban Affairs and Planning in the College of Architecture and Urban Studies at Virginia Tech, in partnership with Arlington Economic Development (AED).
