The purpose of the statistics is to follow the changes in the extension and land use of central business districts and to attach this to demographic and economical statistics concerning the central business districts. The work is based on the need for a uniform delimitation of central business districts as the "national policy guidelines for shopping centres outside central business districts" were passed, 8th of January 1999. An automatic method can secure the authorities standardised data for comparison, as well as providing planning authorities with data for statistical analysis.
The central business districts are modelled for the purpose of statistics, and must not be confused with the term central business district used in other settings.
The statistics is mainly used by civil administration (ministries, directorates, county- and municipality administrations) as well as for research purposes. Population in central business districts is used in a number of analyses as an important variable in social, environmental and demographic studies.
The statistics comprises all Central business districts of Norway as defined by Statistics Norway with minimum 50 employees.
Data sources are the National register of Ground, Addresses and Buildings and the Central Register of Establishment and enterprises.

Not all the relevant enterprises are identified by coordinates and thus some centre zones may be omitted in the statistics.
The delimitation is done by automatic routines using a geographical information system. The central business districts has been delimitated yearly since 2000. In 2010 the method was adjusted. Only businesses with employees make up the basis for delimitation. Centre zones must have at least 50 employees. New delimitations has been made for previous years and new statistics has been produced. The new standard classification of industries are implemented from 2009 onwards.
