State profiles on youth in adult courts were compiled for each of the 50 states, the District of Columbia, and the Federal District Courts. This volume contains profiles for the North Central states of Illinois, Indiana, Iowa, Michigan, Minnesota, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. The first part of each state profile describes the process by which youths are referred to adult courts and what can happen to them after conviction. Included in this part are descriptions of (1) the court organization, (2) the pertinent statutory provisions in the state code, (3) the relevant cases tried in the state supreme court and the federal courts since 1950, and (4) the correctional placement options for juveniles convicted in adult courts. This information was obtained through a search of the statutes and case law and through telephone interviews with court and correctional officials. The second part of the profile presents data collected from every county in the state on the frequency of referral of youths to adult courts through each of the mechanisms permitted by state law. In addition, demographic information, offense characteristics, and the judgments and sentences received by these youths are described for the most populous counties and counties referring five or more juveniles to adult courts in 1978.
