The comparative sociology of the structure, dynamics, and experience of urban relegation in the United States and the European Union during the past three decades reveals the emergence of a new regime of marginality. This regime generates forms of poverty that are neither residual, nor cyclical or transitional, but inscribed in the future of contemporary societies insofar as they are fed by the ongoing fragmentation of the wage labour relationship, the functional disconnection of dispossessed neighbourhoods from the national and global (...) economies, and the reconfiguration of the welfare state in the polarizing city. Based on a methodical comparison between the black American ghetto and the French working-class banlieue at century's turn, this article spotlights three distinctive spatial properties of `advanced marginality' — territorial fixation and stigmatization, spatial alienation and the dissolution of `place', and the loss of a hinterland — and draws out their implications for the formation of the `precariat' in postindustrial societies.
