To rank the best counties to live in, 24/7 Wall Street developed an index based on the United Nation’s Human Development Index, measuring educational attainment, poverty rate and life expectancy to determine the counties’ well-being.
The D.C. region did well on the list, “where a large share of residents have access to advanced, high-paying jobs in government and defense,” according to 24/7 Wall Street. “Major employers in Falls Church, Arlington County, Fairfax County and Alexandria include the U.S. Department of Defense. the Department of Homeland Defense, the Department of Commerce, defense contractor Northrop Grumman and government services company Booz Allen Hamilton.”
The City of Falls Church, a separate jurisdiction, was included with counties for 24/7 Wall Street’s ranking purposes.
