“Of 472 civilian occupations defined by the Department of Commerce, only six are majority immigrant (legal and illegal). These six occupations account for 1 percent of the total U.S. workforce. Many jobs often thought to be overwhelmingly done by immigrants are in fact majority native-born: 51 percent of maids are U.S.-born, as are 63 percent of butchers and meat processors, and 73 percent of janitors.”
