What does primate-city dominance mean?
A primate city is far larger than the country's second city and disproportionately dominant in economic, political or cultural functions.
Formation process and geographic mechanism
Capital-city investment, colonial ports, centralized government, hub-focused transport and agglomeration economies can strengthen dominance. As people seek jobs and services in one center, firms also prefer the large market, creating self-reinforcing growth. Functional concentration matters alongside population ratios.
Spatial outcomes, measurement and management
Dominance may provide global connectivity and efficiency but can intensify housing pressure, congestion and regional inequality. Investment in universities, transport, public institutions and production across secondary cities can rebalance growth. Not every large capital is a primate city; rank-size and functional networks must be assessed together.
