*Change is and has always been a constant. That’s becoming clearer and clearer as far as demographics and how it affects America’s cities and politics. The Washington Post has a story that illustrates how profoundly immigrants are changing the region.

Washington is among eight big-city metropolitan regions in which minorities became a majority in the past decade, according to a new analysis of census data showing white population declines in many of the largest metro areas.

Along with Washington, the regions surrounding New York, San Diego, Las Vegas and Memphis have become majority-minority since 2000. Non-Hispanic whites are a minority in 22 of the country’s 100-biggest urban areas.

“What’s happened is pivotal,” said William Frey, a demographer with the Brookings Institution who conducted the analysis. “Large metropolitan areas will be the laboratories for change. The measures they take to help minorities assimilate and become part of the labor force will be studied by other parts of the country that are whiter and have­n’t been touched as much by the change.”

A report this spring by the Northern Virginia Regional Commission noted that the number of students enrolled in the area’s eight school districts grew by almost 119,000 from 1995 to 2010. The number of white students rose by barely 1,000. The rest were minorities.

“What has happened in the past 15 years in the public schools of Northern Virginia is literally mind-boggling,” the report says. “Even for a region accustomed to constant and accelerated change, the spectacularly swift transformation of the racial and ethnic profile of Northern Virginia’s school-aged population is without precedent.”
