The world's most expensive cities to live in have been revealed in a major survey of almost 300 population hubs.

The destinations are named in the 14th Annual Demographia International Housing Affordability Survey: 2018.

It analysed 293 metropolitan housing markets in nine countries - Australia, Canada, Hong Kong, Ireland, Japan, New Zealand, Singapore, the UK, and the US - in the third quarter of 2017.

Using the "median multiple" approach, which involves taking an area's median house price and dividing it by - the median household income. So if the aver gae income was $50,000 and the average house cost $250,000, the median multiple would be 5.

The method found 26 "severely unaffordable" locations, with the worst offenders in the USA, Australia, New Zealand, Canada, and China.

The survey also looked at all cities, non-major markets included - which is the data we've compiled below.
