In 1940, Portland's African-American population was approximately 2,000 and largely consisted of railroad employees and their families. During the war-time liberty ship construction boom, the need for workers drew many blacks to the city. The new influx of blacks settled in specific neighborhoods, such as the Albina district and Vanport. The May 1948 flood which destroyed Vanport eliminated the only integrated neighborhood, and an influx of blacks into the northeast quadrant of the city continued. Portland's longshoremen racial mix was described as being "lily-white" in the 1960s, when the local International Longshore and Warehouse Union declined to represent grain handlers since some were black.
At 6.3%, Portland's African American population is three times the state average. Over two thirds of Oregon's African-American residents live in Portland. As of the 2000 census, three of its high schools (Cleveland, Lincoln and Wilson) were over 70% white, reflecting the overall population, while Jefferson High School was 87% non-white. The remaining six schools have a higher number of non-whites, including blacks and Asians. Hispanic students average from 3.3% at Wilson to 31% at Roosevelt.
