Statistical processing

Source data

Public and research libraries report data to Statistics Denmark via an electronic questionnaire. The Ministry of Culture provides population for the statistics.

Frequency of data collection

Most of the data is collected once a year, while data for individual-based library statistics is collected continuously via electronic reporting.

Data collection

Questionnaire and delivery from libraries administration system are used for data gathering. From the libraries administration system there is data on loans, stock, active loaners, et cet. From the electronic questionnaire there comes information on staff, finance and number of visitors.

Data validation

Data from the individual libraries is checked in relation to their reporting for previous years. In case of major fluctuations, contact the library for an explanation. In this connection, the libraries may detect errors in the report from the previous year, which are also corrected together with the update for the current year. Data from the libraries' management system (number of loans, stock, etc.) is checked for errors. Errors could, for example, be a missing code in the data delivery, which means that data cannot be loaded into statistical registers. In the event of faulty data delivery, the data will be re-reported.

Data compilation

The data is collected at the same level of detail as the final statistics are published on. During the data process the data is grouped and coded to match the categories in the Stat Bank.
