Washington -- Rural America now accounts for just 16 percent of the nation's population, the lowest ever.
The latest 2010 census numbers hint at an emerging America where, by midcentury, city boundaries become indistinct and rural areas grow ever less relevant. Many communities could shrink to virtual ghost towns as they shutter businesses and close down schools, demographers say.
More metro areas are booming into sprawling megalopolises. Barring fresh investment that could bring jobs, however, large swaths of the Great Plains and Appalachia, along with parts of Arkansas, Mississippi and North Texas, could face significant population declines.
These places posted some of the biggest losses over the past decade as young adults left and the people who stayed got older, moving past childbearing years.
For instance in West Virginia, now with a median age of 41.3, the share of Americans 65 and older is now nearly double that of young adults 18-24 - 16 percent compared to 9 percent, according to census figures released Thursday. In 1970, the shares of the two groups were roughly equal at 12 percent.
