The decision to emigrate has historically held differing promises and costs for women and for men. Exploring theories of difference in labor market participation, network formation and the immigrant organising process, on belonging and diaspora, this books looks at two centuries of migration from the perspectives of women and men separately and together. Investigating the subject globally over time, the book incorporates the history of migration in Yemen, Sudan, the Netherlands, France, Belgium, Poland, the Soviet Union, the US, and the UK, an approach that allows for patterns to emerge over time. The book further shows that although there are various points on which migrant men and women differ, and several theories exist to explain these differences.
