Mostly an agricultural community in its early days, the area made its name by producing many of the fruits and vegetables used around the country. When the Great Depression hit, however, the local economy crumbled and many of the area's more than 2,000 residents left to make a life elsewhere.

Following the Depression, development along south-central Florida's roads, combined with the rise of nearby St Petersburg as a major city, contributed to the Pinellas Park area bouncing back to prominence. The population boomed to 11,000 by 1960, to 40,000 by 1985 and to an estimated 47,572 in 2004. As a result of voluntary annexiarions, the size of Pinellas Park has grown from 7.41 square miles in 1950 to 15.65 square miles in 2003.

Located within the city limits of Pinellas Park are over 3,300 businesses, ranging in size from sole proprietorships to major corporations that employ hundreds of area workers. The Pinellas Park/Gateway Chamber of Commerce, Inc. Serves as the "voice of business" to Pinellas Park businesses, as well as businesses located in the greater mid-Pinellas County area. The Chamber strives to expand its services and programs in order to meet the changing needs of the area's business community.For interest of the History of Pinellas Park, click on this link: pinellasparkhistoricalsociety.org. population recorded by the U.S. Census Bureau is 47,166 . ...
