This number of Quaderns presents the results of two research projects of the program I+D+i financed by the Spanish Ministry of Education for the period 2008 to 2011. The first project is called 'New poverty and social exclusion among youth in Spain' and was supervised by Ph. D. Ignasi Brunet. The second project was developed under the name of 'Poverty, social exclusion and gender inequality in Spain' and was supervised by Ph. D. Ángel Belzunegui. Both projects counted with a group formed by researchers from six Spanish universities from different regions where field work was carried out: Andalucía, Aragón, Cataluña, Comunidad Valenciana, Murcia y País Vasco. The first project has analyzed poverty and youth exclusion in Spain, focusing on the logic that lays behind the social processes of impoverishment and exclusion that effect young people. The second project intended to analyze from a gender perspective the logic of impoverishment processes that affect women, as well as to analyze how women interpret and define poverty.
