"If current trends continue," says the Pew Research Center, "the population of the United States will rise to 438 million in 2050...and 82% of the increase will be due to immigrants arriving from 2005 to 2050 and their U.S.-born descendants...."
Other points they make:
"--The Latino 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% of the U.S. population in 2050, compared with 14% in 2005.
"--The non-Hispanic white population will increase more slowly than other racial and ethnic groups; whites will become a minority (47%) by 2050.
"--The nation’s elderly population will more than double in size from 2005 through 2050, as the baby-boom generation enters the traditional retirement years. The number of working-age Americans and children will grow more slowly than the elderly population, and will shrink as a share of the total population."
The opening phrase is key, of course -- "If current trends continue" -- but if they do, they suggest a more diverse and older America.
