Because water brings essential resources and advantages for growth. Briefly, the main reasons are:
- Transportation and trade: rivers, coasts, and ports let people and goods move cheaply and efficiently. Before railroads and highways, waterways were the easiest long-distance routes, so trade and commerce concentrated there and cities grew up around ports and river mouths.
- Reliable freshwater: cities need drinking water, irrigation, and sanitation. Settling near rivers or lakes made supplying large populations much easier.
- Food and fertile land: river floodplains and coastal deltas are often very fertile, supporting agriculture and stable food supplies that let populations increase.
- Industry and energy: many industries historically used water for power (mills, hydropower), cooling, and processing. Factories and later power plants clustered where water was accessible.
- Strategic and defensive advantages: rivers and bays can be natural defenses, and controlling a port has long been a geopolitical advantage.
- Economic agglomeration and infrastructure: once trade and industry concentrate in a place, secondary businesses and services cluster there (banks, markets, administration), reinforcing growth.
You can still find big inland cities (e.g., Mexico City, Moscow, Johannesburg) where other factors—mineral resources, political/administrative decisions, or overland trade routes—drove growth. But globally, the combination of transport, water supply, food production, and industrial use explains why so many large cities are near water.
If you want, I can give historical examples or discuss how climate change and sea-level rise are affecting coastal cities today.
