Zurich is the city with the highest quality of life in 2006, while Baghdad, for the third year running, has the lowest, a survey published on Monday shows.
Geneva and Vancouver made the top three in the list compiled by human resource company Mercer while Bangui in the Central African Republic and Brazzaville, the capital of Congo Republic, joined Baghdad in the bottom three.
The top three cities in the list are all unchanged from last year.
Chicago is one of the biggest climbers in the rankings since 2005, rising to 41st from 52nd due to reduced crime rates, while Cairo is one of the biggest fallers, sliding nine places to 131st out of 215 cities.
"(This was) due to political turmoil and terrorist attacks in the city and surrounding area," Mercer said.
Mercer bases its annual survey on 39 quality-of-life factors, from political stability to schools, bars, restaurants and the environment.
