The aim of this work is to know attitudes towards immigration, the causal powers over poverty and its relationship with ideological self-positioning in a sample of university students in Bilbao. It is proposed to analyse the relations between these variables, taking as a hypothesis the positive relationship between the centre-right political ideology and greater support for individual causal powers, as well as a more unfavourable and restrictive attitude towards the migrant group. Analyses of bivariate correlations, comparison of averages and binary regression analysis were performed. Significant differences were found in the attitude towards the migrant community and the causal attributes of poverty according to the political ideology of the participants. The dimensions ‘equality principles and policies’ and ‘individualistic powers’ appear as the main independent variables explaining the ideology of participants.
