Vancouver topped the list of the world's most liveable cities for the fifth straight（连续的，笔直的） year, while Melbourne claimed second place from Vienna and Australian and Canadian cities dominated¹ the list's top 10 spots.

In the annual survey by the Economist² Intelligence Unit, the Canadian west coast city and 2010 Winter Olympics host scored 98 percent on a combination of stability³, health care, culture and environment, education, and infrastructure⁴ -- a score unchanged from last year.

It has topped the list from 2007.

Although Melbourne pipped（破壳而出） the Austrian capital for silver medal, there was no other major change near the top of the list of 140 cities worldwide. Auckland, New Zealand, came in 10th.

"Mid-sized cities in developed countries with relatively⁵ low population densities⁶ tend to score well by having all the cultural and infrastructural⁷ benefits on offer with fewer problems related to crime or congestion⁸（拥挤，充血） ," said Jon Copestake, editor of the report, in a statement.

Pittsburgh was the top U.S. city with 29th place -- just ahead of Honolulu -- while Los Angeles moved up three places to 44th and New York held onto the 56th spot.

London moved up one place to 53rd while Paris came in at number 16.

The top Asian city was Osaka at number 12, tying Geneva, Switzerland and beating out the Japanese capital of Tokyo, which came in at 18.

There was also little change at the bottom, with Harare, the capital of Zimbabwe, once again claiming the worst position with a rating⁹ of 37.5 percent, narrowing beating out the Bangladesh capital of Dhaka.

The Economist Intelligence Unit survey ranks cities based on 30 factors such as healthcare, culture and environment, and education and personal safety.
