Statistical processing

Source data

Each quarter, the individual accommodation reports data concerning the users who are enrolled or discharged from the accommodation facility. The statistics include all registered stays of a user during the year.

Data are collected from section 110 shelters in 2022. Accommodations that are covered by the statistics must report enrollment and discharges. In addition, at the enrollment information is obtained on where the user stayed lately, and what type of stay it was according to shelters by section 110. In regards to the discharged, question about how the discharged took place and where the user was discharged to is asked. The collected data are linked to information from the population register in Statistics Denmark.

Frequency of data collection

Data are collected on a quarterly basis.

Data collection

Data are submitted to Statistics Denmark via an upload solution at http://www.virk.dk. Data can be reported by using either a system-generated txt file or a spreadsheet, which Statistics Denmark sends digitally to the accommodation. The spreadsheet is updated by manual inputs by the accommodation and submitted to Statistics Denmark every quarter through a safe upload solution at http://www.virk.dk. The accommodation is notified by email when it is time to report data to Statistics Denmark. If data are not received, the accommodation will be reminded. The accommodation will be reminded twice by email, after which they will be reminded by telephone.

The accommodations who submits data using the spreadsheet from Statistics Denmark, continues inputting their data into the same spreadsheet, until Statistics Denmark digitally sends a new. When the accommodations receive a spreadsheet from Statistics Denmark, the accommodation manually inputs cpr-numbers (ID), enrollment date, type of stay as well as the type of stay for the users, who already is enrolled at the shelter.

Data validation

The statistics cover the years 1999-2022. Since 2020, the accommodations were asked to approve their data at a summary level of a 3-year period before publication. For the statistical year of 2021, the accommodations have been asked to approve data from 2020-2022 Thus, there is a variable that indicates whether the data has been approved or rejected by the institution for the year in question. Since data are approved at a summary level per year, a stay that extends over several years may have a period that is approved for one year, while another period of the same stay may be rejected. However, only a few accommodations rejects data. In 2022, one accommodation rejected data, while another accommodation never provided data. No accommodations rejected data in 2022.

The reported data has been validated. In this connection, data has been checked for duplicates, incorrect civil registration numbers as well of errors and omissions. Data are merged with the population register in Statistics Denmark for further information about the users.

The tables have been validated on the basis of information on enrollments, where simultaneous enrollments have been registered for the same user on the same or several different accommodations. In these cases, there are double registrations, which in some cases cover the entire year, while in other cases there are only double registrations for a few days.

Data compilation

Some accommodations also have a shelter unit where the users are checked-in in the evening and checked-out in the morning. If these stays are in direct continuation of each other without interruption at the same type of accommodation, the stays are converted to one stay.

In some cases where a question has not been answered, “Not stated” is inserted.

If there are two subsequent check-ins or check-outs for a user at the same accommodation facility, a check-in or check-out will be inserted for the day after the first registration so that the stay will be registered as lasting one day. This means that the statistics probably overestimate the number of stays lasting one day.

Pooling is done with information from Statistics Denmark's population register.

If a user is registered with overlapping stays at the same institution or at different institutions, these stays are treated in according to a number of rules. Read more about these rules in [Treatment of Overlap on Residence] (http: // colectica: 25233 / File / 2688a6c5-8b12-4736-81b2-96c6277f2648) in compiling these statistics.

Adjustment

Only totals on a national level are published in the tables, as the units becomes too spare if published at institutional or municipal levels. The accommodations have approved or rejected data before publication. Between 0 and 5 per cent of the total population have rejected data.

The national totals is therefore enumerated to take into account the institutions that have rejected data. This is done on the basis of how many people the institutions have had enrolled per day in average during the year.
