the exact boundary of the area may be in dispute. central florida tends to be thought of as the area around metropolitan orlando, including orange, osceola, seminole, lake, brevard, and volusia counties. polk and sumter counties are considered by some, including the local media, to be part of central florida. although geographically in the central part of the state, usually the west central coast, including hillsborough, pinellas, pasco, and hernando counties, is considered the tampa bay area or the suncoast, rather than a part of central florida. this area is known as the i-4 corridor.
