A separate study was also conducted by PwC, to compare the perceived results of the first study, with quantifiable factors – to determine whether these cities really did live up to their reputations.

London also came to the top of this list, but Paris slipped to fourth place, beaten by Singapore and Toronto. Amsterdam came in fifth, and New York slipped down to sixth place.

This latest research contradicts the recent annual Global Liveability Ranking, which placed London way down in 53rd place as a result of petty crime and a growing terror threat. London also didn't make it into the top 10 most peaceful countries in the world.
