THE PRIMARY PURPOSE OF THE SURVEY WAS TO OBTAIN DATA ON THE ORGANIZATION, JURISDICTION, FUNDING, STAFFING, AND CASELOAD OF PROBATION AND PAROLE AGENCIES TO UPDATE THE DIRECTORY OF CRIMINAL JUSTICE AGENCIES ('CRIMINAL JUSTICE AGENCIES IN REGIONS 1-10'; 10 VOLUMES, NCJ-19730-38 AND NCJ-15151). THE REPORT CONTAINS TABLES SHOWING THE NUMBER OF PROBATION AND PAROLE AGENCIES BY FUNCTION, BY EMPLOYMENT SIZE, BY NUMBER OF CLIENTS UNDER SUPERVISION, AND BY SOURCE OF FUNDING. OTHER TABLES PRESENT THE NUMBER OF EMPLOYEES BY TYPE AND THE NUMBER OF CLIENTS BY SEX, AGE (ADULT OR JUVENILE), AND OFFENSE TYPE (FELONY OR MISDEMEANOR FOR ADULTS; STATUS OFFENSE OR DELINQUENT ACT FOR JUVENILES). DATA ARE ALSO PRESENTED ON THE NUMBER OF PRESENTENCE INVESTIGATIONS CONDUCTED BY PROBATION AND PAROLE AGENCIES DURING 1976. MOST TABLES DISPLAY DATA FOR INDIVIDUAL STATES AND THE AGGREGATE OF COUNTY AND MUNICIPAL AGENCIES WITHIN THE STATE. THE REPORT ALSO CONTAINS A PROFILE OF THE PROBATION AND PAROLE SYSTEM IN EACH STATE, DESCRIBING EACH AGENCY'S LEGAL AUTHORIZATION, ORGANIZATION, PERSONNEL, AND FUNDING SOURCE (FEDERAL, STATE, OR LOCAL). DEFINITIONS OF THE TERMS USED IN THE REPORT AND A COPY OF THE DATA COLLECTION QUESTIONNAIRE ARE ALSO INCLUDED. (AUTHOR ABSTRACT)
