WASHINGTON — For the first time, more than half of the children under age 2 in the U.S. are racial and ethnic minorities, part of a sweeping racial change and a growing age divide between mostly white, older Americans and fast-growing younger ethnic populations that could reshape government policies.
Preliminary census estimates also show the share of African-American households headed by women now exceeds African-American households with married couples, reflecting the trend of declining U.S. marriages overall.
The findings, based on the latest government data, offer a preview of final 2010 census results being released this summer that provide detailed breakdowns by age, race and household relationships.
Demographers say the numbers provide the clearest confirmation yet of a changing social order, one in which racial and ethnic minorities will become the U.S. majority by midcentury.

"We're moving toward an acknowledgment that we're living in a different world than the 1950s, where married or two-parent heterosexual couples are now no longer the norm for a lot of kids, especially kids of color," said Laura Speer, coordinator of the Kids Count project for the Baltimore-based Annie E. Casey Foundation.
"It's clear the younger generation is very demographically different from the elderly, something to keep in mind as politics plays out on how programs for the elderly get supported," she said. "It's critical that children are able to grow to compete internationally and keep state economies rolling."
Currently, non-Hispanic whites make up just under half of all children 3 years old, which is the youngest age group shown in the Census Bureau's October 2009 annual survey, its most recent. In 1990, more than 60 percent of children in that age group were white.
More babies of color than white babies
William H. Frey, a demographer at the Brookings Institution who analyzed the data, said figures in the 2009 survey can sometimes be inexact compared with the 2010 census, which queries the entire nation. But he said when factoring in the 2010 data released so far, minorities outnumber whites among babies under age 2.
The preliminary figures are based on an analysis of the Current Population Survey as well as the 2009 American Community Survey, which sampled 3 million U.S. households to determine that whites made up 51 percent of babies younger than 2. After taking into account a larger-than-expected jump in the minority child population in the 2010 census, the share of white babies falls below 50 percent.
Twelve states and the District of Columbia now have white populations below 50 percent among children under age 5 — Hawaii, California, New Mexico, Texas, Arizona, Nevada, Florida, Maryland, Georgia, New Jersey, New York and Mississippi. That's up from six states and the District of Columbia in 2000.
At current growth rates, seven more states could flip to "minority-majority" status among small children in the next decade: Illinois, North Carolina, Virginia, Colorado, Connecticut, South Carolina and Delaware.
By contrast, whites make up the vast majority of older Americans — 80 percent of seniors 65 and older and roughly 73 percent of people ages 45-64. Many states with high percentages of white seniors also have particularly large shares of minority children, including Arizona, Nevada, California, Texas and Florida.
"The recent emergence of this cultural generation gap in states with fast growth of young Hispanics has spurred heated discussions of immigration and the use of government services," Frey said. "But the new census, which will show a minority majority of our youngest Americans, makes plain that our future labor force is absolutely dependent on our ability to integrate and educate a new diverse child population."
