This articls aims to analyse interrelationships among boy's social origin, school achievement, educational attainment and delinquency, based on the result of the research project entitled “Comparative Study on Adolescent Delinquency in Industrial Societies” planned by Jackson Toby, an American sociologist.
The project aims to compare subcultural delinquency in several sccieties in relation to the attitude of young people, and their sccial origin and educational attainment.
Problem; In this interrelationships among adolescent delinquency are treated as a dependent variable, differential attitude toward education (educational attainment, school achievement) as intervening vasiables and boys' sccio-economic background as an independent variable.
Procedure; 6172 boys born in 1942 selected from graduating classes of 30 public junior high schools in Tokyo were traced back to their attitude toward J. H. S. education, educational career and delinquent acts recorded by the police.
I. Of the 6172 J. H. S. graduates, 415 boys were arrested by police by the time they reached 20 years of age. Rate of delinquency was 6. 7%.
II. Rate of delinquency i) by sccial class ii) by educational attainment and iii) by school achievement in J.H.S. are shown in Tables 1, 2, and 3. i) Larger per cent of boys from bluecollar families than from white collar families have records of delinquency. ii) Higher the educational attainment of boys the less likely they have delinquent records. iii) The lower the school achievement of boys in J. H. S., the more likely they have delinquent records.
III. Figures 1, 2, and 3 show the interrelationships i) between sccial origin (S. O) and educational attainment (E. A) and delinquency (D)., ii) betweend S. O and school achievement (S. A) and D., iii) between E. A S. A and D. i) Difference of delinquent rate (d. r) by E.A within the same S.0 is larger then by S. O within same E. A. ii) Difference of d.r. by S. A within same S. O is larger than by S. O within same S. A. iii) Difference of d.r. by S.A within same E. A is larger than by E. A. within same S. A.
IV. Figures 4 indicates associations of each pair in terms of coefficient. S. O-D: 0.10, E. A-D: O. 17, and S. A-D: O. 22, S. O -E.A: 0.45, S. O-S. A: 0.23 and E A-S. A: 0.55.
