Intended to be an instructive, yet sobering, introduction to the complex and disturbing nature of the juvenile justice system, this article details the "numbers," including selected percentages, ratios, and dollar amounts, that are relevant to developing a better understanding of the juvenile justice system. General statistics about juvenile and adult correctional systems in the United States are compared with similar data for U.S. public schools (e.g., prevalence of learning and behavior disabilities among school-aged children and those who are incarcerated). Lastly, the benefits of providing educational services for incarcerated juveniles, along with statistics related to recidivism and potential costs to our society, are included.
