🏙️ Why do cities make economies more productive?
Urbanisation is not simply about having more people in one place. It is about the economic value created by proximity.
When people, firms, talent, infrastructure and ideas come together, cities generate powerful agglomeration economies:
→ Deeper and more diverse labour markets
→ Greater specialisation
→ Knowledge and innovation spillovers
→ Shared infrastructure and services
→ Thicker markets for skills, capital and business
→ Higher productivity and better economic opportunities
But these benefits are not automatic.
They depend on how cities are planned, connected, governed and managed. Poorly planned urban growth can create congestion, housing pressures, infrastructure deficits and inequality—eroding the very productivity advantages that make cities valuable.
The central lesson of urban economics is simple:
«Cities create value not merely by concentrating people, but by enabling them to interact, exchange, specialise and innovate more efficiently.»
That is why urban planning is ultimately economic policy.
Cities are outcome of markets and policy.
