California
This economic downturn in America came with a severe drought in the Great Plains area which made it even more difficult for farmers to survive and let thousands of them without savings, without jobs, with debts and with no other option than to travel west to California, which hadn't been affected by drought and, potentially, had jobs for farmers. The migration was such that it became an exodus, for example, 18.4 percent of Oklahoma's population, (approximately 440,000 people) left.
