2. Background and purpose

2.1. Purpose and history

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.

2.2. Users and applications

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.

3. Statistics production

3.1. Population

The statistics comprises all Central business districts of Norway as defined by Statistics Norway with minimum 50 employees.

3.2. Data sources

Data sources are the National register of Ground, Addresses and Buildings and the Central Register of Establishment and enterprises.

3.3. Sampling

None

3.4. Collection of data

Based on registers and the use of GIS.

3.5. Control and revision

Data revised by owners of the registers, e.g. Statistics Norway and Norwegian Mapping Authorities.

3.6. Estimation

Based on modelling. Where density and diversity of enterprises fulfils the definition, a centre zone is delimited.

3.7. Confidentiality

None

4. Concepts, variables and classifications

4.1. Definitions of the main concepts and variables

Statistics Norway's definition

1. A centre zone consists of one or more centre kernels and a 100-metre zone around them.

2. A centre kernel is an area with more then 3 different main types of economic activity with centre functions. In addition to detail trade, governmental administration or health and social services or social and personal services must be present. The distance among enterprises must not be more than 50 meters.

At least 50 employees in the centre zone.

Number of centre zones, area of centre zones. Attached statistics; number of enterprises, number of residents, number of employees.

4.2. Standard classifications

None

5. Sources of error and uncertainty

5.1. Measurement and processing errors

Errors of registrations in the National register of Ground, Addresses and Buildings or the Central Register of Establishment and enterprises.

5.2 Non-response errors

None

5.3. Sampling errors

None

5.4. Other sources of error

Not all the relevant enterprises are identified by coordinates and thus some centre zones may be omitted in the statistics.

6. Comparability and coherence

6.1. Comparability over time and space

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.

6.2. Coherence with other statistics

00.00.20 Regional
