Childcare before school start

Information on enrolled children and employees are obtained primarily from registration in municipalities through the municipalities' and regions' payroll office. Data is examined for errors and all municipalities validate their data in dialogue with Statistics Denmark. I

Source data

Data for the statistics comes from several different sources, but can be divided into 3 types; data on registered children, data on employed staff, and data on day care facilities.

Both data on registered children and day care centers come from the municipal place guidance systems.

Information about staff comes from a number of sources, all of which relate to the payment of wages. Information on municipal staff is reported via the Municipalities and Regions Payroll Data Office, which also reports data on staff in the self-governing institutions whose salaries are paid through the Municipalities and Regions Payroll Data Office. For the independent institutions, the source is their salary supplier or the institutions themselves.

In order to be able to correct for maternity-related leave, data from Arbejdsmarkedets Tillægspension (ATP) is used on the payment of benefits linked to maternity leave.

In addition, Statistics Denmark's own registers of education are also used: the Elevregister Kvalifikationsregisteret as well as Register over højest fuldførte uddannelse.

Frequency of data collection

Data is collected yearly.

Data collection

Data on institutions and enrolled children is provided through a system-to-system solution from the municipalities' place guidance system.

Data on municipal staff is reported via the Municipalities and Regions Payroll Data Office, which is automated. For some independent institutions, the staff are also paid by the municipalities, which means that staff data is included in the delivery from the Municipalities and Regions Payroll Data Office.

Self-owned institutions that are not paid through the municipal system can use an external pay system that supplies data to Statistics Denmark. This leaves a smaller group of self-owned institutions that do not have a payroll system provider. These institutions report manually through a form reporting solution on Statistics Denmark's website.

Data validation

Overall, two validation procedures are performed. 1) Error detection of data and 2) dispatch a validation report and engage in dialogue with municipalities. Step 1: The first part of the data collection is done by reviewing the received data from the data providers. This is done by comparing the new data with previous years data. In addition to comparing data across years, comparisons are also made between annual data and monthly data to assess whether there is compliance between them. Step 2: After data have been checked for errors, an account is made of the numbers of children and staff in each municipality. Subsequently, a validation report is prepared, which is then sent out to each municipality. The municipalities add their assessment of children and employees and the assessment from Statistic Denmark are compared to the assessment from each municipality.

Data compilation

Child and staff data are imported as annual extracts from pay systems in the municipalities. Then, an overall quality control and debugging is done in dialogue with the data providers. When data is received, groups are grouped in relevant staff groups and after completed education.

In the inventory of the ratio between children and employees students is weighted with 0,43 while pedagogical interns are weighted with 0.24. The reason for weighting employees is that students and interns also spend time on teaching and receiving guidance. The weighing of personnel follows the recommendation from the “Normeringer i dagtilbud: Model for en årsopgørelse af normeringer i dagtilbud fra 2014” (The ratio of children per adults in daycare – A model to calculate the yearly ratio of children per adults in daycare).
