Lagos, Nigeria’s economic hub, is struggling with its rapid growth. Estimated to have 17.2 million residents by 2025, according to InternetGeography, the city faces a severe housing shortage of 3.4 million units, causing rent increases of up to 80% in some areas. Its population, growing by about 600,000 annually, has transformed what was once a modest city of fewer than one million in 1960 into a large megacity. Lagos reached four million residents by 1990 and eight million by 2015. Today, the metropolitan area probably exceeds 20 million, highlighting a crisis that surpasses available solutions.
