But no U.S. cities scored in the top 30.
Mercer Global Consulantcy has released a list of the top 50 cities in the world in terms of "quality of living".
Here are the US cities on the list and their rankings:
32 San Francisco (tied with Adelaide, Australia)
45 Chicago and Washington, D. C. (also tied with Lisbon, Portugal)
49 New York
The number 1 city is Vienna. Vancouver, Canada is number 4.
Having visited Vienna (though more than 20 years ago), I can say it is a very nice city. At number 28 Calgary in Canada beats all the U.S. cities.
This ranking is of a selected list of 221 cities worldwide and is used "to help governments and multi-national companies compensate employees fairly when placing them on international assignments."
