correction: foreign born labor is 17%, not 30%
The Migration Policy Institute issued a correction a few minutes ago. Here is the correct information:
Foreign-born adults of working age (18 to 54) accounted for nearly 17 percent of all working-age adults at the national level, but they represented 36 percent of working-age adults in California, about 26 percent in New Jersey and Nevada, and less than 2 percent in West Virginia.
Also another correction: Foreign-born children under age 18 accounted for more than 4 percent of all children in the United States. This share was higher in California (7 percent) but much lower in Mississippi (0.6 percent).
