A survey published by the Economist Intelligence Unit says Calgary is the fifth most livable city in the world.

The U.K.-based group analyzes 30 factors to establish its annual rankings, including stability, health care, culture, environment, education, infrastructure and personal safety.

Calgary was among three Canadian cities to land in the top ten, with Vancouver taking first spot for the fifth year in a row.

Toronto was ranked fourth on the list of 140 cities worldwide.

The highest ranked U.S. city is Pittsburgh, at 29th place.

The most unlivable city in the world is Harare, the capital of Zimbabwe, the list's authors said.
