In 2008, 24.1 million persons, or 15.6 percent of the U.S. civilian labor force age 16 and over, were foreign born.
By region, the foreign born made up a larger share of the total labor force in the West (24.1 percent) and in the Northeast (17.9 percent) than for the nation as a whole.
In contrast, the shares of the labor force made up by foreign-born workers in the South (13.8 percent) and Midwest (7.8 percent) were less than for the nation.
