Methodological aspects

The Survey on the equipment and use of information and communication technologies in households is an annual sample-based survey conducted by the INE for the whole of Spain. On the basis of an agreement with the INE, Idescat expands upon the results offered by this operation for Catalonia.

The aim of the survey is to report on the ICT equipment (television, telephones and computer equipment, among others) of households and the use that the population makes of computers, Internet and e-commerce.

The target population consists of people that live in main family dwellings. Although the target population consists of people of all ages, in-depth studies are only conducted of those aged 16 years or over. If there are children aged 10 to 15 in the household, each of these is asked a series of questions related with the use of computers and the Internet.

The unit of analysis, in the case of dwellings, corresponds to those that have at least one member aged 16 to 74 years. In terms of individuals, this unit corresponds to people aged 16 to 74 years and children aged 10 to 15 years.

Since 2004, Idescat and the FOBSIC (Technology Observatory Foundation of Government of Catalonia, Ministry of Public Governance and Institutional Relations) have conducted in Catalonia a complementary survey to that of the INE in order to obtain more territorially disaggregated information on the main indicators of equipment and use. These estimates are produced by applying compound estimators in the framework of the small area estimation methodology.
