The largest and fastest increase in population occurred after World War II, commonly referred to as the “Suburban Population Boom.” From 1940 to 1960, the population of the Town of Babylon increased by 485%. The rapid increase of residents brought an increased need for housing, schools, road improvements, stores and commercial developments, and employment. In those short decades, much of the Town of Babylon and its communities changed from rural countryside to suburban neighborhoods.
