In the early 1930s, with worldwide economies sinking deeper into what would become the Great Depression, upwards of 400,000 people crossed the U.S.-Mexico border. They were en route to what for most would be permanent relocation to Mexico.1 Though many traveled from established enclaves in the Midwest and Northeast, the vast majority came from the Southwest, where Mexican America was concentrated. Claims on both sides of the border to the contrary, the mass exodus could hardly be described as voluntary. In addition to the tens of thousands of immigrants subject to stepped-up deportation efforts and state-sponsored repatriations, countless individuals and families were intimidated, “scare-headed” (the term used by an influential local official to describe the Los Angeles campaign) or otherwise coerced into leaving lest they become burdens on the country's overtaxed relief rolls. Significant numbers of the departed were U.S. citizens, swept up in what the progressive journalist Carey McWilliams called “a determination to oust the Mexican.”2
