A STUDY WAS MADE TO LOCATE THE ADULTS IN SIOUX CITY, IOWA, WHO HAD NOT COMPLETED HIGH SCHOOL AND TO RELATE THEIR EDUCATIONAL INTERESTS TO THE PROGRAMING OF ADULT EDUCATION ACTIVITIES. THE POPULATION WAS IDENTIFIED THROUGH THE JUNE, 1964 SCHOOL CENSUS PROCEDURES AND CONSISTED OF 4,714 SCHOOL DROPOUTS BETWEEN THE AGES OF 21 AND 64. INFORMATION WAS OBTAINED THROUGH INTERVIEWS. WOMEN EXPRESSED LESS SATISFACTION WITH THEIR JOBS THAN DID MEN, AND BOTH OCCUPIED THEIR LEISURE TIME IN ACTIVE PURSUITS. ECONOMIC BARRIERS AND EDUCATIONAL SHORTAGES WERE THE MAJOR SOURCES OF DIFFICULTY ENCOUNTERED. THE MAJOR MOTIVATION FOR ADULT EDUCATION PARTICIPATION WAS TO IMPROVE EMPLOYMENT OPPORTUNITIES. THE RESPONDENTS UNDER 40 WERE MORE WILLING TO ENROLL IN EDUCATIONAL ACTIVITIES THAN WERE OLDER RESPONDENTS AND SHOWED A GREATER INTEREST IN BASIC ELEMENTARY AND SECONDARY PROGRAMS. THE RESULTS INDICATE THAT REGULAR SCHOOL CENSUS PROCEDURES HAVE DEFINITE POTENTIAL FOR SURVEYING VARIOUS POPULATIONS SERVED BY THE DEPARTMENT OF ADULT EDUCATION OF THE SIOUX CITY PUBLIC SCHOOLS.
