There was a data breach in 2021 therefore, one should be careful when comparing data from before and after 2021.
Additionally, has there continuously been restored and added new variables, which leads to data breach in these data. In 2017, following information have been restored: referral method, relocation and where the citizen moves after termination. This gives a data breach for these data.
In 2021, information about where the user last stayed prior to staying at the shelter, is collected, this variable replaces referring, and therefore a data breach occurs in this information.
Comparability - geographical
To the best of our knowledge, there are no similar of directly comparable statistics in the EU or internationally with regard to the target group in these statistics (section 110).
Comparability over time
The statistics were originally established by the National Board of Social Appeals in 1999, where it was managed until July 1st 2016. The statistics were then transferred to Statistics Denmark. In 2021 a data breach have been made, and therefore should one be careful to compare data from before and after 2021. The data breach is caused by a registration made from 2021 on one of three types of stay:
- Shelters by section 110 of the Social Service Act
- Shelter units (cancelled from 1.7.2022)
- Aftercare by section 110 of the Social Service Act
However, not all accommodations have earlier registered on all types, but some have. Prior to 2021, the stays will therefore exist of a blend of all three types of stays, but it is not possible to determine which. Since 2021, it has been possible to determine due to the registration of type of stay. There has been established three new tables in the statistical bank from 2021 (HERFOR1-3), where only the stays in a shelter by section 110 is included.
In 2017, following information have been restored: referral method, relocation and where the citizen moves after termination. Some data variables have been cancelled and others added. This gives a data breach for these data.
In 2021, information on where the user moves after termination is collected, this variable replaces referral, and data breach therefore occurs in this information.
Coherence - cross domain
The statistics are the only one at the field and is not immediately comparable with other sets of statistics in terms of contents.
Coherence - internal
Not relevant for these statistics.
