Statistics Denmark has collected data on pupils in Danish primary and lower secondary schools since the 19th century. Comparable data in its current form are available from 2007, when grades 0 to 10/11 began to be compiled. Pupils per class have been recorded since 2009, and special needs education data since 2011. The statistics follow common European guidelines and are comparable with OECD data from other countries.
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
There is not necessarily full comparability between the UDDAKT20 and SPECIAL tables, even though they refer to the same population. This is primarily due to a typical time lag of approximately six months between the releases. During this period, individual schools may have changed school type, which can affect the distribution and reporting in the respective tables.
Other tables in the Statistics Bank that use data related to primary and lower secondary education: HFUDD11: Educational attainment (15‑69 years) by region, ancestry, highest education completed, age and sex HFUDD16: Educational attainment (15‑69 years) by region, highest education completed, socioeconomic status, industry, age and sex HFUDD21: Educational attainment (15‑29 years) by region, ancestry, highest education completed, receiving education, age and sex FORLOB10: From primary and lower secondary school to further education by cohort, school leaving certificate, region district of graduation institutions, educational graduation statement, graduation statement at certain periods, education, sex and ancestry
Coherence - internal
All data sources use the same format and same units, which make the data consistent.
