After the stock market crashed in 1929, many Americans lost their jobs and many families in America's largest cities were unable to pay their mortgages or rent payments. To avoid living on the streets, people built themselves small homes in public places. These shantytowns sprung up all across the nation and housed nearly 30,000 people during the peak of the Depression.

Here is a look inside some of the Hoovervilles in New York City, Portland, and Seattle.

The first Hooverville to spring up was in a barren Central Park in New York City, as seen in this 1933 photo.
