The Expat Insider 2017 survey released on Thursday has put Vietnam in the spotlight as the cheapest place to live for expats.
The country has jumped five places from the previous year to top the 2017 table, confirming how affordable it is for foreigners to live and work here.
The survey was developed by asking 12,519 respondents, representing 166 nationalities and living in 188 countries around the world, how they felt about their financial situation, and whether their disposable income was sufficient to cover their expenses.
The cost of living in each country was compiled from the global cost of living database Numbeo. All amounts are in U.S. dollars and current as of September 2017.
