There are two different data sources included in the production of Idescat that publish data on income and risk of poverty or social exclusion by 2011.
The purpose of this note is to distinguish between the two sources and report on the specificities of each:
The Statistics on Personal Income Distribution and Poverty Risk is an extension of results published from Idescat on income distribution and poverty risk for Catalonia, from the Survey of Living Conditions (ECV).
The ECV is an annual survey conducted by the INE in order to have statistical information on the distribution of income and social exclusion. The first edition dated from 2004, and is framed in the European project EU-SILC.
The objectives of the Statistics of Personal Income Distribution and Poverty Risk focus on obtaining comparative social indicators on the incidence of risk of poverty or social exclusion and material deprivation.
The ECVHP is a quinquennial survey conducted by the Idescat and the Institute of Regional and Metropolitan Studies of Barcelona, in collaboration with the Council of Barcelona and the Barcelona Metropolitan Area, of which there have been two editions, 2006 and 2011.
The aim of the ECVHP is collecting and analyzing data on income, living conditions, changing lifestyles, the structure and stratification of social classes in the country, the characteristics of the different social groups, and the differences among them.
The Statistics on Income Distribution and Poverty Risk, since its first edition in 2004 and so far, provides information on the distribution of personal income through the net annual income of Catalan households, measures the risk to poverty of the Catalan population, posing a Catalan risk threshold and poverty incidence and measuring the composition of poverty through this threshold. Published data have time series allow for all Catalonia without territorial breakdown.
The ECVHP has incorporated into the 2011 edition two new modules concerning income and poverty data from the Catalan population to the traditional content of the questionnaire, following the methodology of harmonized EU-SILC conducted by Eurostat.
The income and poverty data are obtained from an operation for obtaining own territories most disaggregated data that Catalonia, and combine them with other variables related to the living conditions of the population, but there is no time series.
The ECVHP provides data for smaller territories than Catalonia: Barcelona city, provincial, the seven territorial of Catalonia and the metropolitan of the province of Barcelona, and the Statistic Distribution of Income and Risk of Poverty provides comparable data from the 2004 till 2011 for Catalonia, year after year.
