The most urbanized part of Nigeria is the south-west. This is because it is the region with the highest concentration of cities such as Lagos, Ibadan, Abeokuta, and Oyo. Lagos, which is the largest city in Nigeria and one of the fastest-growing cities in Africa, is also located in the south-west region. The region's proximity to the sea and its historical significance as the hub of commercial activities in Nigeria have contributed to its urbanization. The south-west region is also home to a large number of industries and educational institutions, which have further fueled its urbanization.
