Papua New Guinea's capital Port Moresby has been ranked among the world's five worst cities to live in by The Economist business magazine.
In 2004, the same survey ranked Port Moresby the worst in the world.
Despite massive amounts of foreign aid, relative political stability and sustained growth from a resources boom, Port Moresby is still considered one of the world's worst addresses.
The magazine rates Port Moresby ranked 137 out of 140 cities, putting it one step below Nigeria's capital, Lagos, but one above the Algerian capital Algiers and Bangladesh's Dhaka.
Zimbabwe's capital Harare as the world's worst city, while this year's Winter Olympic host Vancouver is ranked the most liveable city on the planet.
The ranking scores each city on 30 factors spread across five areas: stability, healthcare, culture and environment, education, and infrastructure.
