Industrial production index (IPI)
Quantitative indicator of the production of industrial goods (including energy). Measure of the evolution of production without taking into account the effect of prices.

Methodological aspects

The Industrial Production Index (IPI) is a short-term indicator which measures changes in the production activity of the industrial branches. The purpose of the index is to measure change in the volume of gross added value generated by the industrial branches and by industry as a whole. Consequently it measures changes in industrial production without the price effect.

The indexes use Laspeyres methodology, with weightings set for the base year (2015), in line with the information from the Annual Industrial Company Survey (AICS) and the Annual Industrial Product Survey (AIPS).

A continuous survey is taken every month in order to produce this short-term indicator. The industrial products which make up the basket for the IPI base 2015 basically follow the PRODCOM (Community Production) classification for harmonization of statistics for industrial production in European Union countries.

In compliance with EU regulations, since January 2018 the indexes have been published with the new base 2015 and following the new Catalan Classification of Economic Activities 2009 (CCEA-2009). Linked series since January 2002 are also provided.

The index's coverage is extended to the industrial sectors, i.e. mining industries, manufacturing industries and the supply of electrical energy, gas, steam and air conditioning, which are, respectively, sections B, C and D of the CCAE-09.

The information is broken down into the main industrial sectors established by the aforementioned regulations, to which Idescat incorporates for Catalonia an additional disaggregation for equipment goods and intermediate goods. Also offered are the three sections of the CCAE-09 (mining industries, manufacturing industries and the supply of electrical energy, gas, steam and air conditioning) and the divisions of manufacturing industries with a few peculiarities:

  • divisions 10, 11 and 12: food, beverage and tobacco industries;
  • divisions 13, 14 and 15: textile, clothing, leather and footwear industries;
  • divisions 17 and 18: paper, graphic arts and recorded media industries;
  • manufacture of pharmaceutical products (division 21) is differentiated from chemical industries (division 20);
  • divisions 24 and 25: have been broken down into a single branch of e metallurgy and the manufacture of metal products);
  • divisions 26 and 27: electrical, electronic and optical materials and equipment;
  • divisions 29 and 30: manufacture of transport material;
  • other manufacturing industries include: divisions 16 (wood and cork), 19 (oil refining), 31 (manufacture of furniture), 32 (miscellaneous manufacturing) and 33 (repair and installation of machinery and equipment).
