The concept of models of immigrant integration (e.g., French assimilation, Dutch and British multiculturalism) has had a vibrant career in comparative research on Western Europe, accounting for and explaining many national differences. This concept, however, is problematic because it suffers from normative and theoretical misconceptions. Through a comparison of France, Britain, and the Netherlands, this article discusses key problems affecting the use of national integration models in the literature and proposes ways to overcome them. It argues that models should not be considered as homogeneous and stable cultural entities—and even less as independent variables—but as complex structures of reference on the basis of which a multiplicity of conceptions of identity, equality, and inclusion are developed by a wide range of social agents in each national context.
