Comparability

Comparability - geographical

The statistics cannot be compared directly internationally.

Comparability over time

These statistics have been compiled since 1977. However, due to legislative changes in 1985 and 1993, the data is not strictly comparable over the years.

Since January 1993, changes in legislation have resulted in certain measures previously classified as placements in out-of-home care being transferred to the preventive measures policy area. Additionally, a number of new preventive measures were introduced during this period.

Multiple legislative changes in 2006 led to a significant data breach and contributed to a reduction in the quality of reporting. Consequently, data from 2006 is not comparable in several areas with previous years, and the data from 2007 is not unconditionally comparable due to the same reasons.

Since January 2020, data on services granted pursuant to the Juvenile Delinquency Prevention Act (LBU) has been collected. The addition of LBU data has no influence on other legislative sections presented in the statistics. Furthermore, since July 1, 2020, the statistics also include data on services granted pursuant to §11 of the Danish Act on Social Services. This addition has led to a significant increase in the statistics due to the inclusion of §11 data.

Coherence - cross domain

The statistics are interconnected with the data on children and young persons placed in out-of-home care. This connection stems from the municipality's obligation to provide supportive measures to a child, young person, or family before a decision is made to place them in out-of-home care. Additionally, certain supportive measures can only be granted in conjunction with a placement in out-of-home care or after such a placement has been implemented.

The micro-data of the statistics include social security numbers, enabling the data to be linked with other statistical information.

Coherence - internal

Data reported from various sources typically adhere to the same reporting forms. However, if changes are made to the reporting forms, discrepancies may arise as IT suppliers cannot always implement the changes simultaneously. During these transitional periods, the response categories from the old reporting forms are "mapped" to the new categories.
