Statistics Denmark has produced statistics about the number of pupils in the Danish primary and lower secondary education school system since the 19th century. In its present form, the statistics are comparable since 2007. Before 2007, grades 0 to 7 were not compiled. From 2007, all grades from grade 0 to 10/11 are compiled. The number of pupils per class has been calculated since 2009. Information regarding special needs education has been gathered since 2011.
The statistics are produced according to the common European guidelines and are comparable to statistics from other countries published by OECD.
Comparability - geographical
The statistics form the basis for data in the publication "Education at a Glance" with international comparisons of intake and graduations from the educational system.
The statistics are produced according to the common European guidelines and are comparable to statistics from other countries published by Eurostat.
Comparability over time
The possibility for comparisons over time is good. When an education changes level, it is allocated with a new UDD and AUDD code, but both the old and the new codes will be classified on the new level in the Education classification. For basic schools, it is only the pre-school class, which use to be voluntarily, but has been changed into a mandatory class 0 in 2011.
Since 2007, all grades from grade 0 to grade 11 are covered in the statistics. Until 2006, the statistics only included pupils from 8th grade and upwardly. The statistics and The Student register were extended to include data on pre-school through 7th grade from school year 2006-2007.
In 2011, the collection of data about special need education was initiated. STUK under the Ministry of Education collects the data from private schools and boarding schools. They changed the practice in 2017, as the schools no longer have to report the number of hours the pupils receive special needs education.
The method to produce The Basic School Register was changed in 2017 in order to make it more comparable to the Student register. It is now based on the Student Register data collection. Before, it was produced based on the data collection for the special needs education.
Coherence - cross domain
