the survey doesnt really give a good indicator....london as number 2 is based on propertly prices..although its not cheap to live there ..thats why i moved hehehhehe,but to put like china above some usa states is crazy ....they are comparing the most luxury places,ie property and extreme eating out places etc to compare costs of living ...after 20 yrs of travel i can tell you that list is not accurate at all ..unless you compare extreme factors.
