The Economist magazine made this fantastic interactive chart available that compares house prices in different countries. Where available, it compares pricing from 1990 until quarter 3 of 2009. I found it particularly interesting how little the run up in house prices was in Canada versus many other countries including the UK and the US. Although, I am sure that the data is correct for Canada, Vancouver has experienced significant appreciation in the same time period, proving that broad data is difficult in real estate pricing.
I also found it interesting how in some areas, there has been almost no correction.(Australia – in comparison to the US)
