Statistical processing

Source data

Every quarter, the individual women's shelter report data about the women and their possibly brought children who are registered and/or discharged from the shelter. The statistics include all stays registered during the year. The reported data contains information about each stay at the individual center, including the social security number of the woman and any children brought along, as well as the date of enrolment. If the stay has ended, a date for discharge is also indicated. If the woman wants her and/or her children to be anonymous, a fictitious social security number is used. The collected data is supplemented with information from the population statistics register in Statistics Denmark.

Frequency of data collection

Quarterly.

Data collection

Data is reported to Statistics Denmark through a secure upload solution via Virk.dk. Data can either be reported using a system-generated txt file or via a predefined spreadsheet, which is sent digitally by Statistics Denmark. On the information page for data providers Kvindekrisecentre (in Danish only) there are instructions which describe how to report data on stays for women and children in women's shelters.

Data validation

The women's shelters are asked to approve their data at a summary level for a 1-year period before release. By 2023, all women's shelters have approved their data. In addition, the reported information is further validated and subjected to a series of error checks by Statistics Denmark. In this connection, data has been checked for duplicates and valid social security numbers, among other things.

Data compilation

At the end of the reporting period, a data set is made that contains all the reports that have been validated. The entire data set is merged with information from the population register at Statistics Denmark.

For some of the reported cases the woman has either chosen to be anonymous, and therefore the social security number given in the data set is fictitious, or the women's shelter has registered a faulty social security number. In some cases the background information can be generated via so called donor imputation, i.e. if the the children's social security numbers is reported by the women's shelter, this can be to retrieve background information on the woman via the population statistics register, and the other way around if the woman's social security numbers is reported by the women's shelter, this can be to retrieve background information on the children via the population statistics register.

If a woman is registered with different overlapping stays at the same women's shelters or at different centers, these stays are processed according to a number of rules. Read more about these rules in the document on the treatment of overlapping stays at women's shelters.

After the correcting for errors, the number of distinct women and children is counted, and the number of stays and the number of stays with children are also added up before the statistics are ready for publication.

Adjustment

No correction is made, beyond what has already been described under Data Validation and Data Processing.
