New Tampa is a region in Florida that encompasses both a 24-square-mile (62 km2) area within the corporate limits of the City of Tampa, as well as a larger land area that is in unincorporated Hillsborough, but retains a Tampa mailing address. The incorporated portion of "New Tampa" that lies within the city limits of Tampa is one of the largest city neighborhoods. The population has grown rapidly since being annexed by the city of Tampa in 1988. As of the 2000 census, the district had a population of 22,466. Many new master planned residential communities are planned or already under construction. Big-box stores are following the boom in population and are transforming this once rural area.
