Price index for technical testing and analysis

Statistics Norway has been developing an SPPI for technical testing and analysis since the beginning of 2010. The industry in Norway is dominated by a few large and global companies. Almost 80 per cent of the turnover is generated by the companies with more than 50 employees.

The price method for this SPPI is the direct use of prices for repeated services. The sample is drawn according to the principle of probability proportional to size, and counts between 80-90 enterprises. This gives 85 per cent coverage of the turnover in the population.

The CPA classification has been used as a starting point for breaking down the industry into more congruent sub-groups. However, some adjustments have been made and knowledge from the industry itself has contributed to a more general activity-oriented classification.

Statistics Norway will publish this index for the first time in the 2nd quarter of 2012.
