The representative price observation covers more than 1,300 business units and over 5,400 products per month. Since 1994, the observed price is a basic price excluding value added tax and including price supplement making part of sales, in the case of domestic sales; and a price at the national border, converted into forints at the rate of exchange on the day of fulfilment, in the case of export sales.
Producer price index: the weighted average of domestic and export sales price indices.
Domestic sales price index: an index calculated from the net sales of products and services sold inland, with base periods as weights.
Export sales price index: an index calculated from the sales of products sold directly, through an agent, or in a joint venture in external trade, with base periods as weights.
Calculation method: as a first step, a chained measure is calculated by representative item for the reference month. Following this, the commodity-group indices are determined as arithmetic means of price ratios of representative items, then price indices by class are calculated as weighted arithmetic means of commodity-group price indices.
Weights are revised annually, based on data of the "Annual statistical survey of industrial production" (questionnaire No. 1039 in the National Statistical Data Collection Programme (OSAP in Hungarian)).
Weights are the value of annual sales of the products/services in a particular product group two years prior to the reference year, in a particular sales direction.
As weights are changed annually, the change of the weight structure also has an effect on the base indices of aggregates.
Weights for particular years are shown in the attached table: weights.xlsx
Grouping by use: from 1998, it is done according to the requirements of the European Union, using NACE groups (3 digits in TEÁOR). From 2000, the EU modified the end-use grouping of some divisions (MIG: Main Industrial Grouping). The most significant change out of these is that water collection, treatment and distribution was classified from the group of intermediate goods producer branches to the group of energy producer branches.
The Hungarian standard industrial classification of all economic activities’98 (TEÁOR’98) was introduced in industrial producer price index computation in January 1999, which classification fully corresponds to the EU’s (NACE Rev.1.) industrial classification (down to 4 digits, i.e. at class level). From January 2009, the industrial classification is based on TEÁOR’08, which is consistent with NACE Rev.2.
Data suppliers: selected enterprises classified into sections mining (B), manufacturing (C), energy industry (D) or water and waste management (E).
In tables containing fixed-base indices (2015 = 100%), there was a methodological revision (3 May 2018).
