ECONOMIST Intelligence Unit Livable Cities http://econ.st/i4j
Similar result as Mercer ranking, but English speaking cities do well here.
In Asia, Singapore is the 54th most livable city in the world, below San Francisco (US), and a notch above Budapest (Hungrary). Its placing also puts it above cities like Seoul (58th) and Taipei (62nd), but below Hong Kong (39th), Osaka (13th) and Tokyo (19th).
MONOCLE Quality of Life Ranking http://bit.ly/eeW
Monocle loves Japan for its public transportation and creative vibe. So it is somewhat biased.
In summary, if you judge Quality of Life in "western standard", Asia cities are considered 2nd tier.
It is also important to note that the cost of living and real estate price in usual suspects cities from above high quality of life ranking (such as Vancouver, Sydney, Zurich, etc..) is notoriously high.
