Mixtures of Participation and Frequency During Criminal Careers Over the Life Span

Abstract | Word Stems | Keywords | Association | Citation | Similar Titles



Abstract:

A key point of contention in criminal career research lies in the interpretation of the age-crime curve. For Gottfredson and Hirschi, the decline in the age-crime curve in early adulthood reflects decreasing individual offending frequency (λ) after the peak. Blumstein et al. claim that the decline in the aggregate age-crime curve can also be attributable to the termination of criminal careers, and the average value of λ could stay constant (or increase with age) for those offenders who remain active after that peak. Using data from the Criminal Career and Life Course Study - including information on criminal convictions over 60 years of almost 5,000 persons convicted in the Netherlands - and applying a Two-Part Growth Model that explicitly distinguishes between participation and frequency, we previously assessed the participation/frequency debate (Petras, Nieubeerta, & Piquero, 2008) Building upon this prior work, we will now explore the extent to which different subpopulations are present in the development of participation and/or frequency. According to Gottfredson & Hirschi, we would expect to find different developments in frequency, but not in participation, given a sample of convicted individuals. According to a life-course perspective, we would expect to find heterogeneity in both participation and frequency.
