The American workforce has fewer foreign born workers, especially foreign men, than it did a year ago, reflecting the Trump administration’s efforts to enforce U.S. immigration laws and crack down on illegal entry. The number of foreigners in the labor force declined by 550,000 to 31.5 million. The number of foreign-born men in the labor force fell by 962,000 to 17.3 million, and their participation rate fell to 76.1 percent from 77.5 percent. The number of foreign men holding jobs fell by 752,000 to 16.8 million. The population of foreign-born women increased by around 418,000, with a similar increase in the labor force.
