ホワイト・フライト
In the years following World War II, many white Americans began to move away from inner cities to newer suburban communities, a process known as white flight. White flight occurred, in part, as a response to black people moving into white urban neighborhoods. Discriminatory practices, especially those intended to "preserve" emerging white suburbs, restricted the ability of black people to move from inner cities to the suburbs, even when they were economically able to afford it. In contrast to this, the same period in history marked a massive suburban expansion available primarily to whites of both wealthy and working-class backgrounds, facilitated through highway construction and the availability of federally subsidized home mortgages (VA, FHA, Home Owners' Loan Corporation). These made it easier for families to buy new houses in the suburbs, but not to rent apartments in cities.
