Bangalore: According to the recently published report on "Education at a Glance 2011" by the Organization for Economic Co-operation and Development [OECD] has reported that in the past 50 years, the college graduation rates have increased nearly by 200 percent in the developed countries.

The report also showed that even though education has improved across the board, it has failed to improve in an even manner, as there are some countries enjoying much greater rates in terms of educational attainment than the other countries.

Based on the report released by OECD, 24/7 Wall St. has indentified the most educated countries in the world. According to that list, you can see that most of the educated people are from some of the wealthiest countries in the world, which included countries like U.S., Canada, Japan, New Zealand etc. All these countries aggressively invest for the educational system in their respective country.

Although these developed countries had the educated population from a long time, gradually that percentage has increased over the time. The increases are modest compared to developing countries. So, these are the top 5 educated countries identified by the 24/7 Wall St., according to the report provided by OECD.

1.Canada:

In this country, around 50 percent of its population has completed its tertiary education. This percentage is considered the highest rate in the OECD. Every year, the public and private expenditure on education amount up to 2.5 percent of GDP, which is considered as the fourth highest rate in the world. The tertiary education spending accounts for 41 percent, which is the total percentage on education spent in the country. You should also consider that, nearly 25 percent of the students have an immigrant background.
