PLEASE NOTE: All figures below refer populations for individual cities, not the population for urban agglomerations. Thus a city like Manila in the Philippines may have a city population of 1.6 million people (within its official city limits), but a urban area population closer to 10.5 million people. You can see some estimates for urban agglomerations at World's Largest Urban Areas. Additional figures may be available from the U.N. and country population offices/departments. See population.mongabay.com for current population estimates.
