Overcrowding in prisons and jails is the most serious problem facing the criminal justice system today. The National Institute of Justice established the construction information exchange to provide for less costly ways to increase the number of correction facilities. Programs that have proved successful in South Carolina and a few other States are discussed. Details such as planning, feasibility, staff requirement, referrals, incentives, and wages of South Carolina's program are provided. Other States with similar programs are Texas, Florida, and Arkansas.
