To answer your question, FHSAA policies state that schools may be placed in the Rural classification if they are located in geographic areas as determined by the Rural Economic Development Initiative (REDI; Florida statute 288.0656), population density by zip code, and median family income by zip code. The Rural classification is limited to the lowest 40 populated schools that meet these criteria and commit to the Rural classification in the sport of football.
Other states have wrestled with the public-private disparity. In Tennessee, private schools are placed in separate classifications and playoff brackets from public schools. In Georgia, public and private schools are placed in the same classifications, but private and public schools in the lowest 3 classifications are placed in separate playoff brackets.
