Changes in US population coming sooner than expected

(Phys.org) —A major cultural and geographic divide is emerging between Americans under age 35 and over 50, according to University of Michigan demographer William Frey.

"More than 70 percent of today's baby boomers and seniors are white, and they grew up during a time when the nation's minority population was relatively small and consisted mainly of African Americans," said Frey, a researcher at the U-M Institute for Social Research and at the Brookings Institution. "By contrast, 40 percent of those under age 35 belong to minority groups. They have grown up during a period when racial mingling is the norm at school, work, social occasions and houses of worship."

The resulting differences in social and political attitudes will increase economic and cultural tensions in communities across the nation, Frey says, with some areas affected much sooner and more strongly than others.

Frey will present his projections March 19 at a meeting of Society 2030, a consortium bringing together U-M researchers and corporate leaders to prepare for society's changing age structure and other demographic trends.

Based on analyses of the latest U.S. Census data, Frey made the following predictions:

• America will become a majority-minority population well before 2043, the year in which that shift had been expected.
• For those under the age of 18, however, the tipping point will arrive soonest—by 2018.
• Fast-growing states of the West and South will have the youngest and most racially diverse populations, while the noncoastal Northeast, Midwest and parts of the old South will remain home to large numbers of white baby boomers and seniors.

"It's vital for politicians, community and business leaders, and policymakers to pay attention to these changes. The decisions about how to incorporate this generation into the new American mainstream have important implications for our nation's future."
