Sinkholes occur everywhere in Florida because most of the state is a Karst topography. The Central FL region's high concentration of lakes are related either directly or indirectly to sinkhole activity and solution cavity formation. Although that being the case, it is still unlikely that most people will have an issue with them. Here's a link to the My Florida - Florida Geological Survey website that should address most of your questions. Also, Google "Florida Sinkholes" or "Florida Karst" and a wealth of info returns on that search. Have no fear.
