Forty per cent of Europeans refuse to have Roma as their neighbours, while 80 per cent of these do not even have direct contact with them. Using these statistics as a point of departure, this study analyzes how attitudes toward Roma are constructed. It proposes to investigate this process in two similar environments but where local integration policies directed toward Roma differ, resulting in disparate forms of intergroup contact. The analysis is premised on two theoretical assumptions: that the integration of migrants is a local public policy issue and that intergroup contact frames attitudes between majority and minority groups. From semi-structured interviews in the French municipalities of La Courneuve and Ivry-sur-Seine, four theories are empirically tested: the contact theory, the halo effect, the impact of local immigrant integration policies and media influence. This study demonstrates that the implementation of municipal policies in favour of Roma integration can improve their living conditions and thus deconstruct prejudices attributable to their precarious situation. In addition, it illustrates how the media activate, maintain or solidify the way Roma are perceived.
