Resumen
The Encuesta de Condiciones de Vida (Spanish SILC Survey) is an annual survey integrated in the European Statistics on Income and Living Conditions (EU-SILC). The primary aim of this survey is the regular production of statistics on household income and living conditions, collecting key variables like the total household income and the income components. Initially income information was obtained using exclusively the questionnaires. Nevertheless, access to administrative records offers a good opportunity to improve the quality of income data and allows the use of a more efficient collection method. In 2013 a new methodology was adopted in ES-SILC for the production of the income variables based on the use of administrative files (data from the Spanish Tax Agency and the Social Security system), in combination with the information available in the questionnaires.
This paper offers a comparative overview of both methodologies assessing the impact on the main indicators. Also the future scheme of this statistical operation in 2021 is introduced. The new design of the contents will be based on a series of rotating modules that will cover different dimensions of the living conditions of the household.
