 Migration is linked to higher female working rates. Since 2013, labour force participation rates of female migrants have been higher than that of non-migrant women, meaning that migrant women are more likely to work than non-migrant women. In 2017, this was 64% for migrant women and 48% for non-migrant women. Further, women migrant workers' contributions to development are significant. For example, they tend to permit a larger portion of their earnings than men do. These remittances are also more likely to be spent on health, education and community development back home. While women migrants are major agents of development, some face gender specific risks and dangers compared to male migrants. For example, migrant women may be more at risk of trafficking. 81% of human trafficking victims worldwide, recorded by the Counter-Trafficking Data Collective in 2018, were female. Some migrant women may also be in riskier jobs. For example, in 2013, 73% of migrant domestic workers worldwide were women and adolescent girls, who are often vulnerable to exploitation.
