The data for these statistics are received yearly in November/December from The Ministry of Children and Education. This means that the data received by Statistics Denmark have already been corrected for errors. In addition, a thorough error searching and validation of data are done by Statistics Denmark, where data is controlled for fluctuations across time and irregularities at the individual level. The Ministry of Children and Education are involved in cases of substantial corrections.
Source data
The source is the data warehouse of The Ministry of Children and Education. From this data warehouse Statistics Denmark collects information regarding entrants as well as completed and active students in upper secondary education in Denmark.
Frequency of data collection
The statistics are based on information collected once a year by The Ministry of Children and Education.
Data collection
The majority of data is collected by The Ministry of Children and Education as system to-system reporting through administrative systems. Some institutions report manually through spreadsheets or a webpage to The Ministry of Children and Education.
Data validation
The data validation mainly consists of two types of error searching: macro error searching and micro error searching.
Macro error searching focuses on searching for fluctuations on four parameters: population (the number of students per 1 October), entrants, completions, and discontinuations. The numbers for each parameter are compared with the numbers from the previous year for every upper secondary education at the institutional level. If significant and unlikely fluctuations are found, the institution have to either correct the numbers or inform Statistics Denmark that the numbers are correct and show the factual development.
Micro error searching focuses on errors in the data received by Statistics Denmark about specific persons. Examples of micro errors could be an invalid education code or the student's start date being after the end date. A check for overlaps is also made, since there is not always consistency between the dates provided for students changing from one institution to another. Statistics Denmark corrects the dates to avoid the issue of students appearing to be active at multiple institutions simultaneously.
Data compilation
The Ministry of Children and Education aggregate data from the institutions as a total dataset. Statistics Denmark process the data only slightly, since the data is assessed to be of high quality.
Adjustment
No corrections of data are made except what has already been described under Datavalidering and Databehandling.
