Reflecting unprecedented prison expansion, the scale of prisoner reentry has reached new heights. Although the movement of individuals from prison to community is not new, a focus on the phenomenon of reentry at this time sheds light on the consequences of America's shifting sentencing policies, the changes in parole supervision, and the concentrated impact of removal and return of prisoners on disadvantaged communities. The profile of the current reentry cohort shows that prisoners are less prepared for reintegration and less connected to community-based social structures. Linkages between prisoner reentry and the related social policy domains of health policy, family and child welfare policy, workforce participation, civic participation, and racial disparities are examined to show the potential for more systematic reintegration policies. The article concludes with discussion of the implications of a reentry perspective for the development of new strategies for prisoner reintegration.
