In 1995, the World Bank stated that "70 percent of Lagos' population lived in squatted settlements in extremely poor environmental surroundings. Knee-deep floods sweeping raw sewage and refuse inside densely packed homes were frequent in neighborhoods where overcrowding was the norm. While the average residential density for Lagos was about 260 people per hectare, the population density in slums was between 790 and 1240 people per hectare."
