As a student of geography, you've probably already noticed that these are mostly Asian and European cities. There only two American ones, New York and Los Angeles. New York jumped six spots from last year to No. 7, which it shares with Copenhagen, and Los Angeles is tied for No. 10 with Tel Aviv. Interestingly, though, the US cities were the most expensive for utilities and domestic help.
The most surprising thing about the ranking, though, is the number of ties. The top spot, for instance, was split between Singapore, Paris, and Hong Kong. Last year, no slots were shared, and Singapore led the pack. Paris, as CNN points out, has been in the top 10 since 2003 and moved to tie for No. 1 this year, whereas Hong Kong jumped all the way from fourth to first. Though you can't see it here, the most dramatic shift in the report was Istanbul's drop 48-place drop to 120th, which has been attributed to the weakening of the Turkish lira.
Anyway, we're sure no New Yorkers will take any of this into account.
