Following the end of World War II, a lot of veterans came home to the United States. This led to the development of private communities that were intended to be sold or rented out to returning soldiers, resulting in an economic boom. An example of one of the communities built to attract veterans looking for homes is Stuyvesant Town—Peter Cooper Village, which opened in 1947. In 1951, the United Nations relocated from its first headquarters in Queens, to the East Side of Manhattan.
