Bloomberg Business has named Port St. Lucie to its list of 18 cities that will see the most economic growth the next year.

The magazine said that retirement communities in Florida that are buoyed by a surge in baby boomers top the list of fast growing cities. The study was conducted analyzing data in a report from the U.S. Conference of Mayors prepared by IHS Global insight.

Naples topped the list with 4.9 percent, followed by Sebring with 4.8 percent, The Villages with 4.7 percent, Cape Coral/Fort Myers with 4.5 percent. In all, nine Florida cities were on the list. Other areas slated for high growth in 2016 include the San Jose, Calif., Austin, Texas, and Provo, Utah.
