List of most expensive cities for expatriate employees
These are lists of the world's most expensive cities for expatriate employees (not residents), according to the Mercer, ECA International and Xpatulator.com   cost-of-living surveys. Other surveys from online collaborative indices, such as Numbeo, Expatistan, or Eardex are not covered by this article. Various factors enter into a city's cost-of-living for expatriate employees, such as monetary value, consumer confidence, investment, interest rates, exchange rates of the country's currency, and housing costs. This list does not account for cost-of-living savings accrued to local citizens through government-subsidized housing, health care, education, differences in taxation, and many other factors irrelevant to expatriates. Cost of living may be much higher for expatriates than for local residents in a developing country, especially if expatriates expect a standard of living similar to a developed country.
