DATA ON ADMISSIONS IS PRESENTED FOR THE FIVE YEAR PERIOD OF 1970 TO 1975. STATISTICS ON RESIDENTS ARE BASED ON INMATES IN RESIDENCE DURING THE WEEK OF APRIL 15, 1975. DEPARTURE STATISTICS ARE BASED ON ALL THOSE DEPARTING FROM CORRECTIONAL INSTITUTIONS OVER THE 1970-1975 PERIOD. BECAUSE BOTH ADMISSIONS AND DEPARTURE DATA DESCRIBE A FIVE-YEAR PERIOD, IT IS REPORTED IN TWO CATEGORIES: THE PERIOD FROM 1970-73 AND 1974-75. IT IS REPORTED IN THIS MANNER SO THAT THE READER MAY COMPARE THE TWO FIGURES TO ASSESS DIFFERENCES AND TRENDS. THE DATA CONCERNING RESIDENTS IN CORRECTIONAL INSTITUTIONS IN APRIL 1975 WAS SYSTEMATICALLY GATHERED BY A MASTER PLAN REPRESENTATIVE IN EACH INSTITUTION WHO REPORTED WHICH OFFENDERS WERE PARTICIPATING IN VARIOUS PROGRAMS AND ACTIVITIES. IT WAS FELT THAT THE PERIOD SURVEYED (THE WEEK OF APRIL 15, 1975) OFFERED A REPRESENTATIVE PICTURE OF INSTITUTIONAL ACTIVITIES AND PROGRAMS. TYPES OF DATA INCLUDED IN THE PROFILE OF ADMISSIONS INCLUDES MOST SERIOUS OFFENSE, COUNTY OF RESIDENCE, RACE, SENTENCE TYPE, AGE, AND EDUCATION. DATA ON RESIDENTS INCLUDES AGE, OFFENSE, SENTENCE TYPE, EDUCATION, RACE, HISTORY OF DRUG OR ALCOHOL ABUSE, AND PARTICIPATION IN VARIOUS CORRECTIONAL PROGRAMS. THE PROFILE OF DEPARTURES PRESENTS INFORMATION ON THE MOST SERIOUS OFFENSE, THE HISTORY OF PREVIOUS INCARCERATION, THE MAXIMUM YEARS ON BASE SENTENCE, AND THE LENGTH OF STAY OF COMMITMENTS FROM THE COMMUNITY.
