Data source(s) used: European Union Statistics on Income and Living Conditions (EU-SILC): Eu-Silc is expected to become the EU reference source for comparative statistics on income distribution and social exclusion at European level, particularly in the context of the "Programme of Community action to encourage cooperation between Member States to combat social exclusion" and for producing structural indicators on social cohesion for the annual spring report to the European Council. The survey is carried out yearly, and provides both cross-sectional and longitudinal information. A rotational sample design is used. The use of 4 rotational groups allows to follow households up to four years. Household and individual characteristics are collected at the time of the interview, expenses refer to the last 12 months, while income reference period is usually the previous calendar year.
Other data characteristics: Data is defined not significant when sample size is between 20 and 49 units.The current data differ from the previous ones following the update of the reference populations according to census results.The released data for 2008 were revised in 2018 after a correction of the carryover universe coefficients.The main source of income has been updated compared to the previous data and has been calculated on income that includes among the components the value of meal vouchers, the value of non-monetary fringe benefits (with the exception of the company car already previously considered), self-consumption (goods produced and consumed by the family) and supplementary pensions.
