What is a primate city?

A primate city is typically a large and dominant urban center within a country or region, often serving as the economic, cultural, and political hub. They have a significantly larger population and economic output than any other city in the country, usually accounting for a vast majority of the GDP. Primate cities tend to have a high level of social, political, and economic power, which often leads to unequal development and resource allocation across the country. This can also result in over-crowding, traffic congestion, and other urban problems. Examples of primate cities include Mexico City in Mexico, Tokyo in Japan, Paris in France, and Bangkok in Thailand.
