Under-20 minority Americans have become majority in almost one of every six U.S. counties, according to a new analysis, Xinhua reported.
That change is due both to the increase in the number of minority kids and to the declines in the number of non-Hispanic white kids, said the report, released by the University of New Hampshire's Carsey Institute on Wednesday.
Last year, 34 percent of U.S. residents were minorities ( Hispanics, blacks and Asians), but 48 percent of babies born in the country were minorities.
The number of white youths has dropped 5.3 percent since 2000 while the young minority population has grown 15.5 percent.
"It will be hard to define who is a minority in the future," said Robert Lang, a demographic researcher.
The demographic change is happening so quickly that the youngest Americans are much more likely to be minorities than those who are a few years older.
Among youths aged 15 to 19, 60 percent are non-Hispanic whites (the majority), and among those 4 or younger, only 53 percent are white.
