Car Register and Publications

The car register is established in 1992 with the purpose of providing a basis for statistics concerning vehicles in Denmark , their owners and users and their application.

The most important statistic is on new registration of vehicles. It is used as a short time indicator on household consumption and business investment. In addition to this statistics are calculated on used car sales, vehicle stock and energy efficiency.

There are also calculated statistics on the populations access to or purchase of cars, where information on the private owners and users are gathered from the population statistics in Statistics Denmark.

The car register and other registers in Statistics Denmark are also used for statistics and data extracts to internal and external users.

Statistical presentation

The car register is a database with actual and historical information on vehicles and their owners and users.

The most important variables used to describe the individual vehicle are type (passenger car, van, bus, lorry, etc.), manufacturer, model and variant, weight and fuel type, ownership and geographical location.

Calculations are made of the size of the vehicle fleet and its composition as well as calculations concerning changes in the form of new registrations, re-registrations and changes in ownership. Calculations are also made of the energy efficiency of newly registered private cars, investment in new private cars and concerning the population's access to vehicles.

Statistical processing

The sources to the car register and its publications are the Digital Motor Register, DMR, and other population and business registers in Statistics Denmark.

The central tables in DMR are processed to a row of files with new registrations, re-registrations, user shifts, owner shifts and stock figures. Depending on purpose data from the above mentioned registers can be added.

The series with new registrations, supply and leasing as well as used car sales of passenger cars are seasonally adjusted. The quality of the adjustment is high and there clear seasonal patterns.

The car register and the publications are used for short time assessment, environment assessment, as basis for the random sample in the road transport statistics and to illustrate the populations purchase of and access to vehicles.

Data from the register are used in the law model system, in the national account system used and in calculations of the value of private cars in households and enterprises.

Data from the register are used to prepare statistics on paid services.

Accuracy and reliability

The register and the publications are generally highly precise and reliable with only very limited changes to former published data. These corrections does by experience only result in very limited corrections in the main figures formerly published, i.e. less than 0.5 per mille.

The seasonal adjusted series are of good quality with well defined seasonal patterns.

The number of families in the publications of the families purchase of or access to private cars are fully compatible with the numbers in the area of population statistics.

Timeliness and punctuality

  • New registrations of vehicles, monthly. Expected timeliness 2020 7,6 days. Very high punctuality.
  • Energy efficiency of new registered passenger cars, yearly. Expected timeliness 2020 87 days. Very high punctuality.
  • Stock of vehicles, yearly. Expected timeliness 2020 78 days. Very high punctuality.
  • Families access to cars, yearly. Expected timeliness 2020 176 days. Very high punctuality.
  • Families purchase of cars, yearly. Expected timeliness 2020 177 days. Very high punctuality.
  • Value of new registered private cars yearly. Expected timeliness 2020 65 days.
  • Register. The car register is updated 3 days after the previous month.

There are only limited differences between the statistical concepts in Denmark and other countries and they have no influence on the main figures.

There have since 1994 been a few alterations with respect to employment status/job groups, definition of families, municipalities and weight limits. There are within these therefore not full comparability over time.

The transition to the Digital Motor Register, DMR has caused no breaks in data.
