Lagos
Lagos (population 15–20 million in the metropolitan area — the most contested city statistic in Africa, as no reliable census has been completed since 1991; estimates range from 15 to 24 million, making it either the 6th or the 2nd largest city in the world) is Nigeria's commercial capital and the economic engine of sub-Saharan Africa. The city is built on a complex of islands and mainland territory: Lagos Island (the original colonial settlement and current financial district), Victoria Island (the upscale business and nightlife district), Ikoyi (the most exclusive residential area, originally the colonial-era European quarter), Lekki (the rapidly expanding new development along a peninsula southeast of Victoria Island), and the massive mainland districts (Ikeja, Surulere, Mushin, Agege). Lagos is one of the fastest-growing cities in history — adding approximately 77 people per hour — and its energy, chaos and creativity are unlike anywhere else in the world. The city is the center of Nollywood (the Nigerian film industry: the second largest film industry in the world by number of films produced (1,500–2,000 films per year), surpassing Hollywood and second only to Bollywood), Afrobeats (the global music genre that began here with Fela Kuti and expanded worldwide through artists like Burna Boy, Wizkid and Davido), and the most vibrant contemporary art scene in Africa.
