Book excerpt: Current estimates indicate that approximately 2.2 million people are incarcerated in federal, state, and local correctional facilities across the United States. There are another 5 million under community correctional supervision. Many of these individuals fall into the classification of special needs or special populations (e.g., women, juveniles, substance abusers, mentally ill, aging, chronically or terminally ill offenders). Medical care and treatment costs represent the largest portion of correctional budgets, and estimates suggest that these costs will continue to rise. In the community, probation and parole officers are responsible for helping special needs offenders find appropriate treatment resources. Therefore, it is important to understand the needs of these special populations and how to effectively care for and address their individual concerns. The Routledge Handbook of Offenders with Special Needs is an in-depth examination of offenders with special needs, such as those who are learning-challenged, developmentally disabled, and mentally ill, as well as substance abusers, sex offenders, women, juveniles, and chronically and terminally ill offenders. Areas that previously have been unexamined (or examined in a limited way) are explored. For example, this text carefully examines the treatment of gay, lesbian, bisexual, and transgender offenders, and racial and gender disparities in health care delivery, as well as pregnancy and parenthood behind bars, homelessness, and the incarceration of veterans and immigrants. In addition, the book presents legal and management issues related to the treatment and rehabilitation of special populations in prisons/jails and the community, including police-citizen interactions, diversion through specialty courts, obstacles and challenges related to reentry and reintegration, and the need for the development and implementation of evidence-based criminal justice policies and practices. This is a key collection for students taking courses in prisons, penology, criminal justice, criminology, and related areas of study, and an essential resource for academics and practitioners working with offenders with special needs.
