Background

Background and purpose

The purpose of the statistics is to provide information at the county level about the construction of forest roads. Statistics extend back to the working year 1932/33.

Users and applications

The statistics are used by public agencies (Ministries, county authorities), forest owner's organisations and research institutes. In recent years there has been increasing interest from environmental organizations. Results from the forest roads statistics are used in National accounts. The figures are also used annually in the publication National Resources and the Environment.

Equal treatment of users

No external users have access to the statistics and analyses before they are published and accessible simultaneously for all users on ssb.no at 8 am. Prior to this, a minimum of three months' advance notice is given in the Statistics Release Calendar. This is one of Statistics Norway’s key principles for ensuring that all users are treated equally.

Coherence with other statistics

The Division for Environmental Statistics has estimated the total road area in Norway .

Population

In principle, the statistics cover all private forest roads. Data on roads built without public subsidies are however somewhat incomplete.

The data cover roads that are finished and approved during the report year.

Data sources and sampling

Data on roads built with subsidies or public loans come from the Forest Trust Fund (SKAS) database. The Norwegian Agriculture Agency keeps data on roads built without subsidies or loans manually.

Total census.

Collection of data, editing and estimations

The statistical data on newly built and rebuilt forest roads built with subsidies are collected by the Forest Trust Fund (SKAS). The Norwegian Agriculture Agency extracts data from the database and forwards them to Statistics Norway. The County Department of Agricultural Affairs and the Norwegian Agriculture Agency reports roads built without subsidies to Statistics Norway.

If the data are unclear, The the Norwegian Agriculture Agency or County Department of Agricultural Affairs is contacted so that any errors can be corrected.

Comparability over time and space

Initially, when the work on the statistics commenced, it was difficult to break down the data for each year. The overview of forest roads built before 1 July 1950 is therefore a summary of all forest roads built from the working year 1932/33 to 1 July 1950.

Accuracy and reliability

Sources of error and uncertainty

Data on roads built with subsidies are assumed to be complete. Data on roads built without subsidies may not be complete because not all road projects are reported. The collected data on forest road building is therefore regarded as minimum figures.
