Comparability

Comparability - geographical

The statistics on disability measures are not governed by any EU regulation or compiled according to other international guidelines. The data included in these statistics are defined based on Danish legislation, making direct international comparisons unfeasible. Similar statistics are compiled in many other countries.

Comparability over time

The statistics on disability services have been compiled since 2022 and are best compared to previously published data on the subject - for instance in the statistical tables RESHJMTR and RESLED.

These tables are based on summary information, which the municipalities have reported yearly to Statistics Denmark. It is worth noting that there are instances where data cannot directly be linked with regards to some time periods.

For instance, data contained in the statistics on social resources and data published in the current statistics on disability measures can be difficult to link due to differences in methods of calculation. The most significant difference is that the data in current statistic on disability measures is calculated on the basis of CPR-numbers (social security numbers). Another difference is that disability measures, published in current statistics, are reported by the administrative municipality, whereas in the statistic on social resources, the services were reported by the municipalities which actually financed the measures. This can contribute to differences in number of measures for specific municipalities.

Coherence - cross domain

The statistics on disability services for children and youth can be linked to statistics on disabled and disadvantaged adults. This connection arises because children and youth with chronic or long-term physical or mental disabilities may transition into adulthood and be eligible for selected services typically provided to disabled or disadvantaged adults. This continuity in services underscores the relevance of connecting these statistical datasets to understand the broader support framework across different age groups.

Coherence - internal

Data reported from various sources typically adhere to standardized reporting forms. However, when changes are made to these forms, discrepancies can arise because IT suppliers may not implement the changes simultaneously. During transitional periods, responses from the old reporting forms are often "mapped" to correspond with new categories. This mapping process helps maintain consistency and continuity in the reported data despite changes in reporting formats.
