Outstanding student debt in America has hit $1 trillion, students are on the streets of Quebec, demanding no rises in tuition fees, and French professors are bemoaning the rising costs and "Harvardization" of higher education.

But how much do students actually pay around the world?

Using data from the report "Global Higher Education Rankings 2010", from Higher Education Strategy Associates, we've compared the costs of education (largely tuition, but also books and other fees) in 15 countries, and also looked at the median household income to come up with an "affordability" score (the lower the percentage, the more affordable the tuition fee).

In a bid to give some context to the fees, we've also included the highest university in the Times Higher Education world rankings for 2011 - 2012, and the number of universities in the top 100.

NOTE: Data is from a 2010 report, and in some cases tuition may have changed. Comparable countries not listed were excluded because no data was available.
