Statistical processing

Source data

Information on opening or closure of institutions are delivered to Statistics Denmark through system suppliers. These suppliers register the number of children, staff and institutions on day care facilities in Denmark.

Frequency of data collection

Information from the data supplier is received monthly for children in the age of 0-5 years, while data is received yearly for institutions with children in the age of 6 and above. The publication of the statistics are on a yearly basis

Data collection

The count of institutions are constantly updated with new information. Statistics Denmark is continuously receiving information on whether new institutions are emerging or whether institutions are closed down.

Data validation

The comparisons between the existing count of institutions and the new count of institutions from the data suppliers happens in Statistical programs, but the removable or addition of institutions happens manually. To validate changes in the receiving data, Statistics Denmark are making error tracing.

As the count of institutions is the basis for http://www.dagtilbudsportalen.dk institutions have the possibility to correct incorrect information on the portal. This has been done by several institutions. The count of institutions is therefore also corrected continuously by corrections from the institutions.

Data compilation

Statistic Denmark makes an overall error correction on the data received from the data supplier. If data is not delivered as agreed upon, Statistics Denmark contacts suppliers and find a solution. Furthermore receiving data is compared with last year’s data to identify mistakes.

During error correction pronounced mistakes have been identified in the registration of whether school based leisure time facilities (SFO) are private ore independent. The mistakes happens as municipalities register such information incorrectly. Therefore, all private and independent School based leisure time facilities are coded together in the independent category. It is expected that far most of the School based leisure time facilities are independent facilities. Data on integrated facilities is similarly to weak to be published in data for 2018 and are therefore indicated as uncertain.

Adjustment

Corrections have been made to 2017 data, as 2018 data was published. The corrections is made to the variable "all type of ownership" under "type of ownership", which showed only 0 in the 2017 data. The variable has been updated with numbers.
