Where is 90 of earths population?

Approximately 90% of the Earth's population resides in urban areas, particularly in regions of Asia, such as China and India, which are the most populous countries. Other densely populated regions include parts of Europe, Africa, and the Americas. Urbanization drives this concentration, with cities acting as economic, cultural, and social hubs. Consequently, these areas face challenges related to infrastructure, housing, and resource management due to their high population density.
