Nearly four billion people will live in cities by the end of the decade, a tenfold increase since 1950. Many of them came to cities as part of the largest migration in recent history, an immense and ongoing movement of people around the globe. This migration affects not only the people in motion, but also the urban regions where they land. Meanwhile, many countries have grown increasingly divided over questions of immigration, and the nation-state's role as guarantor of citizenship and belonging has become fractured and unstable. For these reasons, cities have become increasingly central to debates regarding immigration. This course provides an in-depth study, region by region, of the rising importance of urban policy and governance in migration in studies. In addition to focusing on different regional trends, we will also investigate how cities are influencing intersectional areas of policy-making, such as climate, health care, education, housing, and employment. And we will explore the new role for cities in international policy-making around migration and mobility as a result of bilateral agreements such as the UN Global Compact for Migration and the UN Global Compact for Refugees, and various multilateral agreements. This course is taught simultaneously at the New School, at SciencesPo Paris, and at Concordia University Montréal. Instructors are Professor Colleen Thouez, Professor Thomas Lacroix, and Professor Mireille Paquet.
