From 1929 to 1936 the United States deported as many as 2 million people to Mexico. Mexico at this time is immediately post revolutionary and it seems like this massive influx people would have had a significant impact on the region. I can find hundreds of articles about the impact to the USA but no information about how Mexico was impacted. What was the impact to Mexico as a result of repatriation programs in the 1930s? Sources greatly appreciated.
There certainly isn't much information on that particular topic, but the main effect that the repatriation program had, was an oversupply of workforce that worsened the crisis as the wages fell, and the unemployment and poverty rised. This was because more of the returnees were miners or farmers and there wasn't anywhere they could work as most of the mines in Mexico closed temporaly and the agricultural production plummeted due to lack of export demand. So, the economic crisis itself made a lot of people lost their jobs, but with the sudden and massive return of inmigrants there were even less chance to got ther jobs back.
