Florida's 20th-Century Boom: From Swampland to Megastate

Population Explosion

Florida's population surged from ~530,000 in 1900 to over 16 million by 2000—a staggering 3,000% increase. It transformed from the least populous Southern state to the fourth-largest nationally.

Key Drivers

1. Air Conditioning & Mosquito Control – Made year-round living feasible.
2. Economic Diversification – Shift from agriculture to tourism, aerospace, finance, and real estate.
3. Retirement Migration – Warm climate, low taxes, and affordable housing drew millions of retirees.
4. Latin American & Caribbean Immigration – Especially post-1960s, enriching culture and labor force.
5. Theme Park Tourism – Walt Disney World (1971), Universal Orlando, and others became global magnets.

Impacts

• Urban sprawl (Miami, Tampa, Orlando, Jacksonville)
• Environmental stress (Everglades, aquifers, coastal erosion)
• Infrastructure strain (roads, water, schools)
• Political transformation into a decisive swing state

Florida's growth reshaped the Sun Belt and redefined American demographics, economy, and politics.
