Why do some countries welcome new arrivals from abroad while other nations are less hospitable? Politics of immigration control starts at the local level, Jeannette Money asserts. Drawing on detailed evidence from Britain, France, and Australia, and more briefly from the United States, she demonstrates that local support for and opposition to immigration is contingent upon economic conditions, as well as the number of foreigners entering the country and their access to the resources of the welfare state. Whether these local pressures are translated into policies of openness or closure at the national level depends on whether the local constituencies are critical to maintaining or gaining a national electoral majority.
