In rich countries, immigrant children are more likely to be poor than native children. But why are these poverty rates so different between countries? In this report from the Institute for Research on Poverty, the authors tend to bring an answer to this question. In their cross-country comparison, they point out the essential role social transfers are playing against poverty. Immigrant poverty is a barrier to integration but the use of these transfers does not have to discourage immigrant integration. A good combination of labour market policies and social benefits can then, according to the authors, give better results in the fight against poverty.
