The hoovervilles were camps set up in a specific location for people to live in that were affected by the Great Depression, and the dust bowl. The people affected by the depression had nothing left and used whatever tools and took any opportunity they could to live. They were formed coast to coast in the United States. America had no money at that time, but they were able to set these camps up to help the people. One of the largest camps was posted in NYC in Central Park. These camps were as good as you would think. The people there had to work hard. Like human pack rats, ordinary people were forced to carry, wheel and drag bits of lumber, tin, cardboard, tar paper, glass, composition roofing, canvas, and other materials to the sites of America's new real estate boom. Day by day the economy was worsening, and more people were loosing homes. These camps were helping the people survive. Between 1929 and 1933, more then 100,000 businesses failed across the nation.
