Here are the top five most expensive cities:
You can get a free overview of the report from Mercer’s website. (The full version of the report, which can be purchased from there too, costs US $600 or €450.)
Kay has been an expat for 25 years. She set up the British Expat website more than 15 years ago, whilst living in London and missing the expat life. These days she spends much of her time lugging computers and cameras around the world. (Dave gets to deal with all the really heavy stuff.)
