Notes:
1) According to the ISCED classification: International Standard Classification for Education 2011. For older data according to ISCED 1997 see archive table 0.23.
2) Some data are included in other columns, therefore, in parts the average values of individual education areas are not comparable to the values of others. For more details see source.
3) The year specifications may differ from the years of reference. For a detailed specification see source.
4) The categories OECD/EU22 average represent those countries that were members of the OECD/EU in the respective year of reference.
5) 2014: EU21 average.
6) 2016: Data should be used with caution.
7) In parts data refer to ISCED 1997, hence data are of limited comparability (see source).
