Data are already validated. However, central variables go through a probability check in form of a comparison with data from the previous year. Data about decisions, charges and admissions to prisons from Statistics Denmark's criminal statistical registers are linked to data from Statistics Denmark's register of the population's highest level of education and Statistics Denmark's register of Populations Statistics.

Explanations of possible big deflections in the distribution of key variables are looked for. E.g. changes in the legislation or in the administrative praxis may cause fluctuations in the distributions.
