Washington, D.C.

A 2007 report found that about one-third of District residents were functionally illiterate, compared to a national rate of about one in five. This is attributed in part to immigrants who are not proficient in English. As of 2011, 85% of D.C. residents age 5 and older spoke English at home as a primary language. Half of residents had at least a four-year college degree in 2006. D.C. residents had a personal income per capita of $55,755; higher than any of the 50 states. However, 19% of residents were below the poverty level in 2005, higher than any state except Mississippi.
