The Mercer survey covers 214 cities across five continents
and measures the comparative cost of over 200 items in each
location, including housing, transport, food, clothing,
household goods and entertainment. It is the world’s most comprehensive cost of living survey and is used to help
multinational companies and governments determine
compensation allowance for their expatriate employees.
New York is used as the base city for the index and all cities are compared against New York. Currency movements are measured against the US dollar. The cost of housing – often
the biggest expense for expats - plays an important part in
determining where cities are ranked.
