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

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

It has topped the list from 2007.
