Hong Kong is no longer the world's priciest city for overseas workers, according to the results of Mercer's 2021 Cost of Living survey. Find out which city is the most expensive and why the results have been impacted by the pandemic and other factors.

(CNN) — Ashgabat in Turkmenistan is the most expensive city in the world for overseas workers, according to this year's Mercer Cost of Living Survey. The annual report ranks 209 cities based on the comparative cost of expenses including housing, transportation, food and entertainment, with New York City used as a baseline comparison. The Turkmenistan capital, which was number two on last year's list, is something of an outlier in the top 10, which mostly features business hubs like Hong Kong (last year's priciest city and this year's second priciest), Tokyo (number four for 2021), Zurich (number five for 2021) and Singapore (number seven for 2021).
