Lagos is Nigeria’s economic focal point, generating a significant portion of the country’s GDP. Most commercial and financial business is carried out in the central business district situated on the island. This is also where most of the country’s commercial banks and financial institutions and major corporations are headquartered. Lagos has one of the highest standards of living as compared to other cities in Nigeria as well as in Africa. The Port of Lagos is Nigeria’s leading port and one of the largest and busiest in Africa. It is administered by the Nigerian Ports Authority and it is split into three main sections: Lagos port, in the main channel next to Lagos Island, Apapa Port and Tin Can Port, both located in Badagry Creek, which flows into Lagos Harbour from the west. The port has seen growing amounts of crude oil exported, with export figures rising. Oil and petroleum products provide 14% of GDP and 90% of foreign exchange earnings in Nigeria as a whole.
