This article investigates residential segregation at the intraurban level of migrants in two Italian cities, Rome and Milan, considering religion as a point of reference in light of its pivotal role in terms of identity references for many migrants. The article focuses in particular on Muslim migrants-due to both the magnitude of their presence and complex issues related to their settlement in Italian cities. The analysis shows a low level of intraurban residential segregation of Muslim migrants in both cities, with some relevant differences related to national subgroups (e.g., a higher concentration for people coming from Bangladesh and Pakistan), so that religion seems not yet to be a main driver of residential choice for Muslim migrants. In light of both the low level of segregation of Muslim migrants and some features of Italian urban policies on migration and religion, we argue that residential concentration can currently play a beneficial role in terms of the insertion of migrants in Italian cities and fulfillment of some of their needs (e.g., availability of minority places of worship). Introduction: Migrations, Religion, and The City During the last decades, issues related to international migrations to European countries have gained increasing centrality in the academic and public debate, as well as in the policy agenda. This is even truer for countries-such as Turkey, Greece, and Italy-that, due to their location, are gateways to Europe and have been recently affected by major migration flows related to geopolitical issues in Africa and the Middle East. Against this backdrop, many international organizations, public authorities, and research institutions have focused their attention on ways to foster social cohesion and migrants' integration at the urban scale (see, for instance, OECD 2018). In many cases, these policies (e.g., housing diversification programs) and analyses leading to their promotion (e.g., analysis on residential segregation of migrants) have taken as a point of reference ethnicity or socioeconomic features (e.g., income). In contrast, religion has almost never been taken into account, even if it is often a crucial pillar for migrants in shaping their identity formation and self-definition in host countries (Mitchell 2004; Peach 2002).
