In the past 50 years, college graduation rates in developed countries have increased nearly 200%, according to Education at a Glance 2011, a recently published report by the Organisation for Economic Co-operation and Development (OECD). The report shows that while education has improved across the board, it has not improved evenly, with some countries enjoying much greater rates of educational attainment than others. Based on the report, 24/7 Wall St. identified the 10 developed countries with the most educated populations.

1. Canada

In Canada, 50% of the adult population has completed tertiary education, easily the highest rate in the OECD. Each year, public and private expenditure on education amount to 2.5% of GDP, the fourth-highest rate in the world. Tertiary education spending accounts for 41% of total education spending in the country. In the U.S., the proportion is closer to 37%. In Israel, the rate is 22%. In Canada, nearly 25% of students have an immigrant background.

2. Israel

Although there is no data on the percentage of Israeli citizens with postsecondary education dating back to 1999, the numbers going back to 2002 show that growth is slowing dramatically compared to other countries. In fact, in 2006, 46% of adults ages 25 to 64 had a tertiary education. In 2007 this number fell to 44%. Only 78% of funds spent on educational institutions in Israel are public funds. The country is also only one of three — the other two being Ireland and Sweden — where expenditure on educational institutions as a proportion of GDP decreased from 2000 to 2008. Israel also had the largest increase in overall population, approximately 19% from 2000 to 2009.
