Population distribution is uneven globally, with some areas like near water and food sources being more crowded. Urbanization is increasing as more people move to cities for opportunities, jobs, and amenities not available in rural areas. This population shift causes cities to grow rapidly and density to increase, straining infrastructure and resources.
