Statistics Norway presented the use of the CPI in Norway. The CPI has its most important users among the Ministries, the Central Bank of Norway and in the financial sector. Labour organisations and employers' federations are other important users. The CPI is also widely used in indexation of contracts. Within Statistics Norway the CPI is an important input to the National Accounts. It is also used as a deflator for the Index of Retail Sales. Primary data is used in analysis and research.

The All-item index goes back to 1865 and the primary classification for aggregation and dissemination is COICOP. There are also certain item-indices published each month. The indices published according to COICOP are available from January 1979.

Other products calculated on the basis of CPI are indices according to delivery sectors. This is a much used analytical aggregation, since it is a breakdown of important sectors in the economy.

In the spring 2001, the central bank of Norway was given new guidelines for the monetary policy. In the regulations the central bank was instructed to apply the instruments of monetary policy to establish stable and low inflation. The operational target is an annual growth in consumer prices, that over time, is near 2.5 per cent and the regulation explicitly states - quote: “In general, the direct effects on consumer prices resulting from changes in interest rates, taxes, excise duties and extraordinary, temporary disturbances shall not be taken into account.” After the alterations to the monetary policy, Statistics Norway developed an indicator for the CPI deducted of the direct effect of real tax changes (CPI-AT). The adjustments made in the CPI-AT were then combined with CPI excluding energy products (CPI-AE) into one indicator where the Consumer Price Index is accordingly adjusted for real changes in both taxes and energy prices (CPI-ATE). From May 2007 Statistics Norway also publish series of CPI-ATE seasonal adjusted.
