Hoovervilles was a small town during the The Great Depression . And that's where all the homeless went to stay, they built their own homes since they didn't have money to pay their rent and got kicked out.
During The Great Depression farmers worked hard to make crops . When the prices fell they tried to make even more crops so they could earn more money. But then prices dropped really low that some farmers lost their farms.
When The Great Depression happened many people lost their jobs which meant they couldn't earn money to pay rent or to buy food for their families. So there was 2 million people that became homeless and some even died from hunger.
