The changing face of the heartland

•By 2025, the immigrant share of the population will surpass the peak during the last great wave of immigration a century ago.

•The Hispanic population, already the nation's largest minority group, will triple in size and will account for most of the nation's population growth from 2005 through 2050.

•Hispanics will make up 29 percent of the U.S. population by 2050, compared with 14 percent in 2005.

•Births in the U.S. will play a growing role in Hispanic and Asian population growth; as a result, a smaller proportion of both groups will be foreign-born in 2050 than is the case now.

•The non-Hispanic white population will increase more slowly than other racial and ethnic groups; whites will become a minority at 47 percent by 2050.
