Data sources and sampling

The sample is based on information about the enterprises/establishments market shares collected from Norwegian Post and Telecommunication Authority. Prices and distribution of income on services in fixed phone and mobile phone offered to the business market are collected from enterprises in the sample through questionnaires. List prices on internet services and on services offered to the private market are collected through the enterprises/establishments homepages.

A sample of enterprises are drawn from the population based on information about the market share in fixed phone services, mobile phone services and internet services.

Collection of data, editing and estimations

Electronic and paper questionnaires are used for the collection of data from services in fixed phone and mobile phone offered to the business market. Enterprises in the sample have a three week deadline to submit the questionnaire, and they are obliged to report information. List prices on internet services and on services offered to the private market are collected from the enterprises homepages every month.

The questionnaires are automatically downloaded into an application for control and revision. Every questionnaire is afterwards controlled and revised, both automatically and manually. If price changes seems unlikely large, the respondents are contacted.

Laspeyres price indices for the business market are estimated in an application and they are indicating price changes for services offered to client groups. Client groups in market of fixed telephone services and mobile phone services are defined by the enterprises in the sample. Weights on these services are based on revenue shares on each of the services. Weights on internet services are based on information from the Internet survey published by Statistics Norway, and on information from the enterprises. For the business market an aggregated index per client group are aggregated to an index per enterprise. Indices per enterprise is then aggregated to an index for fixed telephone services, mobile phone service and internet services. These sub-indices are weighted together to an index for the business market.

Price index for the private market is the consumer price index for telecommunication services and is published monthly. The index is converted to a quarterly index (2006=100), and will be adjusted if there are changes in the value added tax.

Price indices for the business market and the private market are weighted together to a total index for the industry.

Accuracy and reliability

Sources of error and uncertainty

Measurement errors might be caused by not correctly answered questionnaires. The respondents can misinterpret or report wrong figures. Processing errors occur mainly after the data is received by Statistics Norway. In general, the production system ensures that the data is controlled on both detailed and aggregated level.

If something suggests a measurement error, the respondent is contacted.

Non-response will always be a factor in questionnaire-based surveys. Some respondents do not return the questionnaires, or the questionnaires are rejected because they are incompletely filled out. 100 percent of the questionnaires in this statistics are returned to Statistics Norway.

The sample is based on the enterprises' market share in the telecommunication industry. A price index must be seen as an estimate on the general price development, within the area of its scope. Sampling errors may cause an estimate that doesn't reflect the real price development.
