Shifting racial demographics have led to lower poverty rates for Asians and Hispanics in much of the Washington region, according to new census data.

The percentage of D.C. Hispanics under the poverty line dropped from 20.5 percent, or 8,968 people, in the 2000 census to 14 percent, or 7,628 people, in the 2007-2011 average. The Hispanic poverty rate in Prince George’s County dropped from 14.1 percent of 55,727 people to 11.7 percent of 122,304 people.
