According to New York City-based Mercer's cost of living survey, Seoul jumped from 15th last year. It was second in 2006 and dropped to 51st in 2009.
The report studied more than 400 cities around the world, comparing the cost of 200 items, including housing, public transportation, clothing, entertainment and food. It also checked how foreigners fared with their neighbors and whether their neighborhoods were safe.
Angola's capital Luanda topped this year's list. It ranked No.2 last year. Monthly rent for a two-bedroom apartment in the city was $6,055 and a hamburger cost $14.58.
Other cities in the top 10 include Hong Kong, Tokyo, Zurich, Singapore, Geneva, Shanghai, New York City and Bern.
