Accuracy and reliability

Overall accuracy

The statistics are based on all 16-24-year-olds who, on the last working day in November, have been resident in the country for at least the previous four weeks. This means that persons who have either left the country before this period or immigrated afterwards are not included.

The population's NEET status is determined according to whether the persons are not in employment last week in November and have not been in education or training in that week and the previous three weeks. However, among those categorized as inactive (NEET), there is a big difference in how long they belong to the NEET group, and it is thus far from all young people in this group who should be designated vulnerable. Yet, as a result of the chosen operationalization, it is not possible to elucidate the diversity of the NEET group in these statistics.

Since the population, including the persons' NEET status, as written above, is identified last week in November, while the information on hospital utilisation, consultations with physicians and purchases of prescription medicine refers to an entire calendar year, the latter information will be misleadingly low for persons who have not been resident in the country throughout the year.

The count of contacts in the table on consultations with physicians is also associated with some uncertainty. The information on contacts comes from the internal Health Insurance Statistics, which are based on the National Health Insurance Service Registry administered by the Danish Health Data Authority. The National Health Insurance Service Registry contains information on services provided by general practitioners, specialists, dentists, physiotherapists, chiropractors, podiatrists, and psychologists who are funded by public health insurance, as the information serves as documentation for these services, so that settlement between the individual provider and the region can take place. Incorrect registrations are corrected by re-registering the relevant service with a minus sign. If an incorrect registration and its correction are not made in the same year, the count of contacts will be wrong.

Sampling error

Not relevant for these statistics.

Non-sampling error

The statistics are based on all 16-24-year-olds who, on the last working day in November, have been resident in the country for at least the previous four weeks. This means that persons who have either left the country before this period or immigrated afterwards are not included. However, this coverage error is not assumed to have any consequences for the statistics. Since the statistics' population, including the persons' NEET status, is identified at the end of November, while the information on hospital utilisation, consultations with physicians and purchases of prescription medicine refers to an entire calendar year, the latter information will be misleadingly low for persons who have not been resident in the country throughout the year.

Quality management

Statistics Denmark follows the recommendations on organisation and management of quality given in the Code of Practice for European Statistics (CoP) and the implementation guidelines given in the Quality Assurance Framework of the European Statistical System (QAF). A Working Group on Quality and a central quality assurance function have been established to continuously carry through control of products and processes.

Quality assurance

Statistics Denmark follows the principles in the Code of Practice for European Statistics (CoP) and uses the Quality Assurance Framework of the European Statistical System (QAF) for the implementation of the principles. This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.

Quality assessment

The statistics are relevant, accurate and reliable, topical, consistent, comparable and directly accessible.

The source data for the statistics come from the Register-Based Labour Force Statistics, as well as from the three health statistics: the Hospital Utilisation Statistics, the Health Insurance Statistics and the Register of Medicinal Product Statistics. Detailed descriptions of the quality of the source data can be found in these statistics' statistical documentation.

These statistics have been developed based on current methods.

Data revision - policy

Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice.

Data revision practice

The statistics only publish final figures. Since these are completely new experimental statistics, no revisions have currently been made.
