Social Security Affiliations. By type of regime and activity sectors

Social Security affiliation is compulsory for all people included in its field of application and is valid for the worker's entire lifetime. It is currently divided into the following regimes: general, special for coal mining, special for agriculture, special for domestic employees, special for the self-employed and special for sea-based workers.

Until December 2008, the data refers to the general regime and to the special one for coal mining; from 2009, the data presented refers to the total number of contributors on the one hand and to the general regime and special one for coal mining on the other. In all cases the information is taken from a statistical exploitation of the contributory records for the different Social Security regimes, the management of which is the responsibility of the General Treasury for Social Security.

It must be considered that contributors are considered if employed or are in assimilated situations (temporarily incapacitated, suspension due to the regulation of employment, partial unemployment, etc.) and the number of contributors does not necessarily correspond to the number of workers, but rather to situations that generate the obligation to make social security contributions: the same person is accounted for as many times as they are in situations where there is the obligation to make such contributions, due to that person being involved in various labour activities in one regime or various.

Until December 2008 the sectoral data is classified in accordance with the Catalan classification of economic activities 1993 Revision 1 (CCAE-93 Rev.1). From January 2009 the results by sectors correspond to the new Catalan classification of economic activities CCAE-2009. This means that the latter are not directly comparable with previous years.
