The main interest of the labour cost statistics is to obtain an estimation of the economic costs of the work factor in the production process of goods and services of an economy. The two basic statistical sources to make estimates of the level and composition of the labour cost are the Quarterly labour cost survey and the Annual labour cost survey conducted by the INE, on the basis of which Idescat performs a statistical exploitation and extends the results for Catalonia.
The Quarterly labour cost survey (hereinafter QLCS) is a continuous statistical operation conducted every quarter by the INE. the main objective of the QLCS is to find out the cost of the workforce, considering the average labour cost per worker and month and by effective hour worked, and also the time worked and not worked. Labour costs are broken down into wage costs and non wage costs. It also provides better knowledge of the time worked and not worked, labour structure, and its short-term evolution.
The Annual labour cost survey (hereinafter ALCS) is an annual statistical operation conducted by the INE and that completes the results obtained by the QLCS and offers an annual perspective of these costs. It is produced on the basis of a questionnaire annexed to the QLCS during the third quarter of the year after the year of reference. The main objective of the ALCS lies in finding out the annual cost per worker of the work factor and its main components: salary expectations, obligatory social security contributions, voluntary contributions, direct social contributions, compensations, professional training costs, transport cost, social costs and other costs derived from the generation of employment.
Until 2007 the population scope for the QLCS and the ALCS included all workers associated with contribution accounts included in the general Social Security regime and the coal mining special regime, regardless of their size. Information was collected on workers that had made contributions at least for one day of the reference month and research was made of the contribution accounts for economic activity in the three main economic sectors: industry, construction and services; specifically, those contained in sections C to K and M to O of the Catalan classification of economic activities 1993 Revision 1 (CCAE-93 Rev.1). The research therefore excludes agricultural and fishing operations, Public administration, defence and compulsory Social Security, households employing domestic services and extra-territorial bodies.
From 2008 the population scope for the QLCS and ALCS is adapted to the CCAE-2009 and contains all contribution accounts included in the general Social Security regime, the coal mining special regime, and the sea workers special regime, the economic activity of which is maritime transport (code 50 of the CCAE-2009), regardless of their size. The research includes all workers that had made contributions at least for one day of the reference month and research was made of the contribution accounts for economic activity in the three main economic sectors: industry, construction and services; specifically, those contained in sections B to S of the Catalan classification of economic activities 2009 (CCAE-2009). The research excludes agricultural operations, households employing domestic services and extra-territorial bodies.
As a consequence of the change to the Classification of economic activities from 2008, Idescat is also publishing estimations of the quarterly labour cost and annual labour cost for activity sectors for the 2000–2007 period calculated using the CCAE-2009, in order to offer the complete series for the main components of the labour cost for all years.
The data published here are the result of an extension of the results for Catalonia and comprise information from the first quarter of 2000 in the case of the QLCS and from the year 2002 for the ALCS.
