Primate cities, characterized by their disproportionately large size and significance compared to other cities in a country, often wield immense influence over the urban spheres in developing nations. Their dominance stems from a concentration of economic activity, political power, administrative functions, and cultural institutions. This centralization attracts significant rural-to-urban migration, as people seek better employment opportunities, access to education, and improved public services. The primate city becomes the primary engine of national growth, drawing in investment and resources, often at the expense of other regions.

However, this dominance is a double-edged sword. While primate cities can be hubs of innovation and economic dynamism, they frequently exacerbate regional inequalities. Resources funnelled into the primate city often leave smaller towns and rural areas underdeveloped, creating a stark spatial imbalance. This can lead to overcrowding, strain on infrastructure, and the proliferation of informal settlements within the primate city itself. Politically, their overwhelming influence can lead to a top-down governance model, where decisions made in the capital may not adequately reflect the needs or aspirations of peripheral regions. Furthermore, the concentration of critical infrastructure makes the entire nation vulnerable to disruptions in a single urban centre. Therefore, while primate cities are undeniably influential, their unchecked growth can hinder balanced national development and deepen spatial disparities in developing contexts.
