About 54 percent of the city is African American and 40 percent is white, the census figures show. At the beginning of the decade, the city was 61 percent black and 34 percent white.
In raw numbers, the District lost about 27,000 black residents and gained about 40,000 whites. Asians now are 4 percent of the population, up from 3 percent in 2000, while Hispanics have risen from about 8 percent to 9 percent. There also were increases in the number of Native Americans and Hawaiian and Pacific Islanders, through the actual numbers and the percentage increases were both very small.
