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

Information on enrolled children is obtained from registration in municipalities which are send to IT-suppliers. The IT suppliers are KMD, IST, ASSEMBLE and in Læsø, data is collected directly from the municipality. Data on employees are obtained through payroll systems. The suppliers for private and some independent institutions are FOBU, BØRNERINGEN, SPIA, Læsø, ACCOUNTOR, LDD, FDDB. For municipal and some self-governing institutions data are collected from the municipalities 'and regions' payroll office (KRL). The statistic also uses Statistics Denmark's own registers on education and maternity leave.

Frequency of data collection

Data is collected yearly.

Data collection

Data on children's enrollment and working hours of employees are obtained through data providers. The municipalities register the staff’s working hours and enrollment of children electronically.

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).
