Lagos, Nigeria is experiencing rapid urbanization as its population grows. It is currently home to over 18 million people and is forecasted to reach 25 million by 2025, making it one of the largest cities worldwide. However, 70% of Nigeria's urban population lives in inadequate housing in poor conditions. This rapid population growth has outpaced infrastructure development, leading to overcrowding, lack of sanitation services, and increased health risks. High rates of poverty and diseases like diarrhea are associated with unsafe and overcrowded living conditions common in disadvantaged urban communities in Nigeria. Environmental health sciences and management are needed to help educate residents and implement safety policies to protect community well-being.
