In countries within the OECD (Organisation for Economic CO-operation and Development, was founded in 1948 to help reconstruct Europe after the second world war with the help from Marshall plan. It is today a organ for collaboration with 34 member countries, OECD is a forum to exchange ideas and experiences and a collaboration to compare statistics and analysis within all areas that can affect the economy and it´s development.) the demands on knowledge has increased, a lot more people therefor chose to get a secondary education (high school) to have a better chance to get in to the labour market. In Sweden 86% of the people between the age of 25-64 have at least a secondary education, witch is a considerably higher number than the rest of the OECD members whose average is 73%.
Here is a chart over the % of people between 25-64 that have a upper secondary education.
Within the hole OECD the demands of knowledge has increased and a lot more therefor chose to finish there secondary education. In order to get in to the labour market it is most of the times necessary to be able to shove some kind of evidence or a diploma from at least your secondary education. This gets more clear if you fore example compare the share of the population with a secondary education in the age 25-34 and the share with secondary education in the age 45-54. A clear trend is that if a big share of the population has a secondary education the difference between the younger and the older group of the population with a secondary education is not that big. But in countries with a lower share of population with a secondary education the younger people in a larger scale have the education in comparison with the older share. Some of the countries were this development has been especially high is Korea, Portugal and Ireland. In these countries the difference between the young share and the old share with a secondary education is more than 20%.
