This research was commissioned by the European Commission to improve understanding of the labour market outcomes of migrant women in the EU, and of the policies that affect these outcomes. Given the European economic and social agendas for growth, equality and social cohesion, this study aims to contribute to understanding migrant women's participation in the European labour force. The empirical results of the study are based primarily on analysis of the anonymised EU Labour Force Survey. Labour force participation, unemployment, involuntary part-time employment, temporary-contract employment, and degree of concentration in low-skill occupations are used in evaluating the labour market outcomes of third-country migrant women relative to native-born women, relative to other EU-born women and relative to third-country migrant men. In-depth analysis of migrant women's labour market outcomes in Spain provides a deeper understanding of the large-scale programs that have regularised the legal statuses of migrant women in those countries. The work-life balance outcomes of third-country migrant women are also examined in depth in order to understand connections of the very low rates of employment of third-country migrant women with young children.
