The chapter provides a description of the Survey of Adult Skills and the differences between migrants and natives in terms of their literacy and numeracy proficiency levels. A discussion follows on the extent to which language and foreign qualifications explain part of such differences. Moreover, the chapter analyses the labour market outcomes (employment, incidence of overqualification and wages) of migrants relative to natives and discusses how these differ across migrant groups as well as the role played by literacy proficiency and other relevant factors.
