why many Mexican families migrated in 1940

Explanation:

The 1940s saw yet another reversal of U.S. policies--and attitudes--toward Mexican immigration. As wartime industries absorbed U.S. workers, farmers became desperate for low-cost labor and urged the government to take action. In 1942, the U.S. and Mexico jointly created the bracero, or laborer, program, which encouraged Mexicans to come to the U.S. as contract workers. Braceros were generally paid very low wages, and often worked under conditions that most U.S. citizens were unwilling to accept. Braceros were treated so poorly in Texas, for example, that for a period the Mexican government refused to send any workers to that state. The program was very popular with U.S. farmers, and was extended well past the end of World War II, not ending until 1964. More than 5 million Mexicans came to the U.S. as braceros, and hundreds of thousands stayed.
