Soon after the war, with the disappearance of Oakland's shipbuilding industry and the decline of its automobile industry, jobs became scarce. Many of the poor blacks who had come to the city from the South decided to stay in Oakland, and longstanding black residents complained that the new Southern arrivals "tended towards public disorder."[46] The segregationist attitudes that some Southern migrants brought with them disrupted the racial harmony that Oaklanders had been accustomed to before the war.[37] Many of the city's more affluent residents, both black and white, left the city after the war, moving to neighboring Alameda, Berkeley, Albany and El Cerrito to the north; to San Leandro, Hayward, Castro Valley and Fremont in Southern Alameda County; and to the newly developing East Bay suburbs, Orinda, Lafayette, Pleasant Hill, Walnut Creek and Concord. Between 1950 and 1960, about 100,000 white property owners moved out of Oaklandpart of a nationwide phenomenon called white flight.[47]
