“…In Europe and North America, systemic microspatial marginal areas are usually located in the centres of major metropolitan areas (Coulton et al, 1996;Wacquant, 1996a;Marcuse, 1997a). Although systemic micromarginality is often attributed to factors that are internal to poor urban communities as exemplified by the "culture of poverty" debate, it is the systemic external forces, including "social gatekeeper" agencies, that seem to be more responsible for the phenomenon (Roscigno and Bruce, 1995;Micheli, 1996;Tosi, 1996;Wacquant, 1993Wacquant, , 1996aMarcuse, 1997a). Systemic microspatial marginality is revealed in those areas in which there is a convergence of many of the stereotypical factors of vulnerability.…”
