Delinquency Careers in Two Birth Cohorts - Classic Criminology Study

In this review of Delinquency Careers in Two Birth Cohorts, the reviewer finds a rigorous historical study best suited to scholars and students of crime and social development; the single biggest reason to read it is its status as a foundational longitudinal cohort analysis that traces delinquency across an entire birth group. The book continues the work begun in Delinquency in a Birth Cohort (1972) and explains methodology, origins, and the University of Pennsylvania project that followed a 1945 cohort of 9,945 boys, offering readers a clear account of early cohort research in American criminology.

Key Features

• Foundational cohort: Documents the first major U.S. birth cohort study initiated at the University of Pennsylvania and explains its intellectual origins and aims.
• Large sample: Focuses on the 1945 cohort of 9,945 boys, giving readers a sense of scale and the practical challenges of long-term follow up.
• Research lineage: Traces inspiration from earlier Norwegian work and Professor Thorsten Sellin, placing the study in international scholarly context.
• Funding and methodology context: Describes the role of a National Institute of Mental Health grant and how external support shaped the study's scope and design.
• Authoritative contributors: Brings together established scholars Paul E. Tracy, Marvin E. Wolfgang, and Robert M. Figlio, whose combined perspectives clarify criminological approaches of the era.

Who It's For

Delinquency Careers in Two Birth Cohorts is aimed at academics, graduate students, and researchers in criminology and social science history who need a close look at early longitudinal methods and cohort findings. It will be particularly useful for those studying juvenile delinquency, life-course criminology, or the institutional history of crime research.

Readers seeking a modern textbook with contemporary data or practitioners wanting prescriptive policy guidance should look elsewhere; this book is primarily historical and methodological rather than a manual of current interventions.

Pros & Cons

Pros

• Provides an in-depth historical account of the first U.S. birth cohort study, valuable for context in historical criminology.
