When it comes to the world's largest cities, there are various ways to measure their population. One method is by looking at the urban areas, which are contiguous built-up areas that function as integrated economic units. By measuring the populations in these urban areas, we can determine the largest cities in the world. In this article, we will explore the top 20 largest cities by population, based on urban area measurements.

Methodology

They rank cities based on their urban area populations, which take into account commuting flows, social interactions, and economic activities. By focusing on urban areas rather than official city limits or metropolitan statistical areas, we can gain a more comprehensive understanding of the size of these cities.
