This is a useful resource – Tom Slater’s ‘An International Bibliography on Territorial Stigmatization‘.

The work on this develops from Loïc Wacquant’s Urban Outcasts, and earlier references, with the suggestion that “the exploration of contemporary urban poverty must start with the powerful territorial stigma attached to residency in the bounded and segregated spaces of ‘advanced marginality’” (Hancock and Mooney 2013, 52).

There is some useful and politically important work here, though I’m still unclear why ‘territorial’ was used as the key geographical term here, as opposed to regional, locational, spatial, place, etc.
