Deltona is the most populous city in Volusia County, Florida, lying on the northern shore of Lake Monroe along the St. Johns River. Located approximately halfway between Orlando and Daytona Beach, the city was home to 85,182 people, as of the 2010 U.S. Census. The city is a part of the Orlando–Deltona–Daytona Beach Combined Statistical Area, which was home to 2,818,120 people in 2010.
The city, originally established as Deltona Lakes, was founded in 1962 as a retirement community. It was master-planned and developed by the General Development Corporation and the Mackle Brothers. The rapid development of housing units since its opening in 1962 led to a major population boom, eventually surpassing Daytona Beach as the largest municipality in Volusia County by 2000. This rapid development has resulted into an almost entirely residential cityscape. Consequently, the city primarily functions as a bedroom community, and depends on surrounding communities for employment, shopping and entertainment.
