Port Harcourt, Nigeria

Capital City

With a population of over 3.4 million, Port Harcourt is Nigeria's fifth largest city - a bustling, oil-rich commercial hub that has seen rapid, uncontrolled growth. The city's economy revolves around the petroleum industry, but air pollution from illegal refineries and gas flaring is a persistent headache for residents. And while Port Harcourt boasts a lively nightlife and music scene, the tropical climate features heavy, year-round rainfall. Overall, this rapidly expanding city may appeal to those drawn to its economic opportunities, but the combination of bureaucratic hurdles and environmental challenges makes Port Harcourt a tough sell for the average expat.
