During the 1950s and 1960s the South Florida metropolitan area grew four times as fast as the rest of the nation. Between 1940 and 1965, 6 million people moved to south Florida: 1,000 people moved to Miami every week.[79] Urban development between the mid-1950s and the late 1960s quadrupled. Much of the water reclaimed from the Everglades was sent to newly developed areas.[80] With metropolitan growth came urban problems associated with rapid expansion: traffic jams; school overcrowding; crime; overloaded sewage treatment plants; and, for the first time in south Florida's urban history, water shortages in times of drought.[81]
