Today in Labor History February 2, 1931: U.S. citizens of Mexican heritage were “repatriated” to Mexico. During the decade’s first four years, the federal government deported anywhere from several hundred thousand to 1.8 million Mexicans. 40-60% of those deported were U.S. citizens and overwhelmingly children. President Hoover blamed Mexicans for the Great Depression and deported them in huge numbers to win support from his right-wing base.
