Nice to see my home town (Bournemouth, UK) is the 6th most expensive city in the world. (This is in terms of housing affordability against local earning power.)
London, the only other UK city in the top 20, ranks 14th.
The most expensive city on earth in these terms is Vancouver, Canada (BC).
The cheapest country on earth to live in you ask? Manytowns, USA.
This is all according to data compiled and analysed by Mish.
