What is the popular density around the city of Cairo?

Cairo is one of the most densely populated cities in the world, with a population density of approximately 19,000 people per square kilometer in the urban area. This high density is a result of rapid urbanization and migration, leading to significant challenges in housing, infrastructure, and public services. The city’s population exceeds 9 million, and when including the greater metropolitan area, this number rises to over 20 million, exacerbating congestion and resource management issues.
