Carceral geography may at first appear rather ‘niche’. Although prisons and criminal justice systems are integral parts of governance and techniques of governmentality, the geographical study of the prison and other confined or closed spaces is still relatively novel. That said, carceral geography has already made substantial progress, has already established useful and fruitful dialogues with cognate disciplines of criminology and prison sociology, and is attuned to issues of contemporary import such as hyperincarceration and the advance of the punitive state. This volume has sought to provide an overview of that progress and of the scholarship which has so far defined carceral geography, in light of the areas of convergence with work in other disciplines.
