190-998: The area, illustrating the difference between high population density and overpopulation . Deserts have very limited potential for growing crops as there is not enough rain to support them. Thus, their population density is generally low. However, some cities in the Middle East, such as Dubai , have been increasing in population and infrastructure growth at a fast pace. Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Very densely populated cities are mostly in Asia (particularly Southeast Asia ); Africa's Lagos , Kinshasa , and Cairo ; South America's Bogotá , Lima , and São Paulo ; and Mexico City and Saint Petersburg also fall into this category. City population and especially area are, however, heavily dependent on
