Data on producer prices in industry by economic activity (NACE Rev.2) expressed in output price index (2010) and percentage change compared to same period in the previous year.

The producer prices are also known as output prices. However, although the STS-Regulations use the term of "output prices", in practice the most used term is "producer prices". The definition in this paragraph reflects the terminology used in the Commission Regulation 1503/2006.

The objective of the output price index is to measure the monthly development of transaction prices of economic activities. The domestic output price index for an economic activity measures the average price development of all goods and related services resulting from that activity and sold on the domestic market. The non-domestic price index shows the average price development (expressed in the national currency) of all goods and related services resulting from that activity and sold outside of the domestic market. When combined, these two indices show the average price development of all goods and related services resulting from an activity.

It is essential that all price-determining characteristics of the products are taken into account, including quantity of units sold, transport provided, rebates, service conditions, guarantee conditions and destination. The indices of domestic and non-domestic prices require separate output price indices to be compiled according to the destination of the product. The destination is determined by the residency of the third party that has ordered or purchased the product. Output prices for the non-domestic market are further sub-divided into output prices for products despatched to euro-zone countries and all other output prices.

The production of indices within Member States is normally based on the compilation of data from numerous sources. All national statistical authorities use statistical questionnaires for collecting STS data. However, their content and style vary greatly, partly because of cultural differences and partly because of the greater or lesser importance attached to respondents' burden and cost. These factors, as well as others, determine what information the national statistical authorities collect. In most of the national statistical authorities, the surveys are rarely restricted to one standard questionnaire or form but tend to be a combination of forms.
