Growing up in poor families supposes higher social exclusion risk, the effects of which persist over time and suppose adulthood disadvantages, including but not limited to a higher risk of poverty in adult life. The main goals of the study are to establish which elements affect child poverty in Spain and Portugal and to check AROPE indicators (At Risk of Poverty or Social Exclusion) for accuracy and adequacy in comparing European poverty. The study was carried out through AROPE comparative secondary data analysis, a multidimensional poverty measure that allows comparison among European countries in the aftermath of the economic crisis (2005–2013). Principal data were taken from Income and Living Condi- tions (EU-SILC, EUROSTAT) and European System of integrated Social Protection Statistics (ESSPROS, EUROSTAT). On one side, AROPE and components (poverty rate, severe material deprivation and households with very low work intensity) are analysed in two populations (younger than 16 years old and dependent children households) in Por- tugal and in Spain to identify differences. On the other, convergences and divergences between the two countries are analysed, finding different child poverty conditional factors as well as different impacts. In Spain, the main predictor is unemployment, while in Portugal, it is the level of poverty in the population. Additionally, we show that the investment and efficacy of social protection polices, through expenditure and social transfers, have a deep impact upon child poverty rate reduction across Europe. Potential mismatches in country comparison subsequent to AROPE construction components are & Eduardo Dı ´az Herra ´iz Eduardo.Diaz@uclm.es Inmaculada Herranz Aguayo Inmaculada.Herranz@uclm.es 1 Faculty of Social Sciences, University of Castilla-La Mancha, Avenida Real Fa ´brica de Seda, S/n, 45600 Talavera de la Reina, Spain 2 Higher School of Social Work of Porto, Instituto Superior de Servic ¸o Social do Porto (ISSSP), Av.
