The 5 most educated countries in the world

The Organization of Economic Cooperation and Development recently released its Education at a Glance 2012 report. Here are the five most educated countries in the world.

4. Japan

Post-secondary education: 45 percent of the population
Annual growth rate for that group: 2.9 percent

In Japan, the fourth most educated country in the world, students pay some of the highest tuitions among OECD countries: Japan has the fourth highest fees for higher education behind the US, Korea, and Britain. Additionally, the government spends only 0.5 of its GDP on post-secondary education, less than half of the OECD average of 1.1 percent of GDP.

Nearly 32 percent of Japan's funding for post-secondary education comes from private sources – the third highest percentage of privately sourced funding in the world.
