SRCV : Statistics on Income and Living Conditions - 2021
Data description
The European Union Statistics on Income and Living Conditions (EU-SILC) is an annual instrument aiming at collecting timely and comparable cross-sectional and longitudinal multidimensional microdata on income, poverty, social exclusion and living conditions. This instrument is anchored in the European Statistical System (ESS). The SRCV survey (Statistiques sur les ressources et conditions de vie) is the French component of EU-color-rgb(23,25,28)SILC.color-rgb(23,25,28) In addition to the annual questionnaire, are collected thematic module variables every three year, six year or ad-hoc new ponctual needs modules.
The EU-SILC instrument provides two types of data:
-
Cross-sectional data pertaining to a given time or a certain time period with variables on income, poverty, social exclusion and other living conditions
-
Longitudinal data pertaining to individual-level changes over time, observed periodically over four year rotation scheme
Social exclusion and housing condition information is collected mainly at household level while labour, education and health information is obtained at individual level for persons aged 16 and over. The core of the instrument, income at very detailed component level, is collected according to the type of income, at the household or individual level. Income amounts are generally not requested, as the survey is enriched with social and fiscal administrative sources after collection.
Statistical unit
Person living in ordinary housing
Statistical population
Data refers to all private households and individuals living in "ordinary" dwellings in the metropolitan France at the time of data collection.
The scope of the SILC survey is all individuals in a household occupying, at the time of the survey, a so-called "ordinary" dwelling whose residence is located in metropolitan France.
Thus, populations living in communities (hospitals, schools, religious communities, etc.) are not included in the scope of the survey.
Reference area
France métropolitaine
The reference year for incomes is N-1.
Comparability - geographical
The sample size of the EU-SILC survey, around 25,000 respondents in France metropolitan, and the number of regions, 13, 9 of which have fewer than 800 respondents, make it impossible to calculate reliable poverty indicators for each region. This is why INSEE has developed a small area estimation method, which will provide micro-data (weights) for each region, allowing the calculation of poverty rates at regional level.
The calculation of regional indicators, using the NUTS2 level split of the DB040 variable__, is strongly discouraged on data prior to 2022.__
Comparability - over time and CC2. Length of comparable time series for U
A significant series break took place in 2020 following the redesign of the system the year before the implementation of the IESS Regulation.
Source data
The French data are taken from the statistics on income and living conditions (SILC): the majority of the data are taken from the SILC survey. The amounts for income and social security benefits are then obtained by matching with administrative data (taken from tax and social security sources).
Data compilation
In 2020, the FR-SILC survey was redesigned, in order to comply with the IESS regulation.
The whole statistical processing and editing chain has been rewritten (from SAS to R). The new weighting and imputation procedures are described.

Sample size
The sample size of the SRCV survey is approximately 14,000 respondent households in France, i.e. 25,000 individuals over the age of 16
