Bill Levitt tried to create inexpensive homes for American families, especially those individuals who were involved in World War II. Upon returning home from war, many men came back to start families with the wives they left behind. Since home construction was very limited during the Great Depression and World War II, there was a need for the development of a significant amount of homes.
These homes, developed by Levitt, helped spark the development of suburbs in the 1950's. These communities were aimed at luring young families into areas where the homes could accommodate their growing families.
