Living Conditions Survey 2004-2011

Summary

Strengths: The Living Conditions Survey (LCS, in Spanish ECV) belongs to the evermore complete set of harmonised statistical operations for European Union countries, following EU agreements (http://www.ine.es/en/daco/daco42/condivi/reg_condivi_en.htm). ECV provides the European Commission with a first-class statistical instrument for poverty and inequality studies, a follow up of social cohesion within the relevant territory, the study of population needs and the impact of social and economic policies on households and people, as well as the design of new policies. The ECV is an annual survey directed at households and was preceded by the European Community Household Panel (ECHP) carried out during he 1994-2001 period. Both surveys have similar characteristics and objectives and the EUHP contributes valuable experience to the new survey. Although data relate both to cross-sectional and longitudinal dimension, priority is given to the high quality cross-sectional data, while the longitudinal component goes back in time to the same people, studies the changes that occur in their lives when conditions and socio-economic policies are changed, and how they react to these changes. There are also several annual ad-hoc modules to approach specific research questions, such as: Intergenerational transmission of poverty (2005, 2011), Social participation (2006), Dwellings conditions, equipments and problems (2007), Over-indebtedness and financial exclusion (2008), Material deprivation (2009), Ability to take decisions (2010) Weaknesses: The survey does not cover all aspects to measure living conditions. Some of the income collected by the survey is under-reported compared with administrative data.

Coverage

Coverage Years of collection, reference years, and sample sizes
Data collection is ongoing since 2004. It is an annual survey with a rotational-group design. The sample is comprised of four independent sub-samples, each of which is a four-year panel. Each year, the sample is rotated in one of the panels. The initial sample size used was around 16,000 dwellings in each wave, weighted differently according to the household and individual samples. The income reference period is the previous calendar year.

First year of collection
2004

Stratification if applicable
In each Autonomous Community, first-stage units are stratified by the size of the municipality to which the census section belongs.

Base used for sampling

Geographical coverage and breakdowns
