Poinciana is a census-designated place (CDP) in Osceola and Polk counties in the U.S. state of Florida. It lies southwest of Kissimmee and about 14 miles (23 km) east of Haines City. As of the 2010 United States Census, it had a population of 53,193.
As of June 2011 the population was reported as 69,746, according to "Box Score", a demographic breakdown of each of the 10 Villages which make up the Association of Poiciana Villages (APV). The difference from the Census figure is due to "Box Score" counting neighboring census tracts that are included within the original Poinciana PUD boundary defined by the State of Florida but not included in either the "Poinciana Pioneer" or CDP population count. According to the latest census reports these adjoining tracts represent an additional 29,914 persons. Depending on the definition, the greater Poinciana Area represents a population of between 53,193 and 83,107.
This puts Poinciana as one of the fastest growth areas for Central Florida over the past decade.
