The source of the statistics is The Central Register of Reported Criminal Offences - administered by the National Commissioner of the Danish Police. Data are delivered quarterly via System-to-system-transmission. The data go through a probability check in form of a comparison with data from the previous year, key variables are checked for valid values and irrelevant offences are deleted.
Key series are seasonal adjusted. Seasonal adjustments are made for sexual offenses, crimes of violence, offence against property and other offences, as well as selected subcategories where there may be registered seasonal variations. Be aware that the effect of COVID-19 has made data more uncertain than usual.
