Where Humanity Lives: 98.5% on Land, 1.5% on Water

The United Nations confirms a striking geographic fact: 98.5% of the global population lives on land. Only 1.5% reside on water—houseboats, floating villages, stilt settlements, and artificial islands.

Land Dwellers: The Overwhelming Majority

• Coastal concentration: ~40% live within 100 km of coastlines
• Urban acceleration: 56% urban (2023), heading to 68% by 2050
• Density extremes: Manila (43,000/km²) vs. Mongolia (2/km²)

Water Dwellers: Niche Adaptations

• Floating villages: Tonlé Sap (Cambodia), Ganvié (Benin), Uros Islands (Lake Titicaca, Peru/Bolivia)
• Houseboat communities: Srinagar (Kashmir), Amsterdam canals, Seattle houseboats, Hong Kong Aberdeen
• Stilt settlements: Makoko (Lagos), Koh Panyee (Thailand), Sangihe Islands (Indonesia)
• Artificial islands: Malé (Maldives), Dubai's Palm, Kansai Airport (Osaka), Flevopolder (Netherlands)

Why So Few on Water?

Water lacks freshwater access, sanitation, stable substrates, food production space, energy infrastructure. Climate change threatens low-lying water communities first. Yet rising seas may force managed retreat and floating city prototypes (Oceanix, Maldives Floating City) from experiment to necessity.

For now, Earth is a land species' planet. The 1.5% on water are pioneers of a wetter future.
