Although most people agree that a city is an area with lots of buildings and people, it can be difficult to define what constitutes a city for demographic purposes. World Urbanization Prospects states that there are three main ways to define a city. There’s the city itself, which is the legal boundaries of the city, and there’s an urban agglomeration which includes all connected urban areas or densely settled areas within the city. Then there’s a metropolitan area, which encompasses the area of suburbs and communities where most of the population commutes into the city regularly. The majority of these numbers are urban-agglomerations. some are not due to specific characteristics or traditions. The largest gap between these numbers is in, which has approximately 10,000,000 residents and 30,000,000 in its agglomeration.
