This study extends research on cohort effects and crime by considering how bifurcated population dynamics and institutional constraints explain variation in homicide rates across racial groups in the United States. Drawing upon the extensive research on racial residential segregation and institutional segmentation, we theorize how the criminogenic influences of cohort characteristics elucidated in prior work will be greater for Black cohorts than for White cohorts. We assess our hypothesis by estimating Age-Period-Cohort Characteristic models with data for the total population and separately for the Black and White populations over the 1975–2014 period. The results reveal persistent effects of relative cohort size and nonmarital births on Black cohort-specific homicide rates but null effects among the White population. These effects follow Black birth cohorts across the life course, leading to higher rates of both homicide arrest and homicide victimization.

Victims play a central role in criminal case processing, but research suggests many victims do not report crimes to police or cooperate in a police investigation. This study extends the literature on victim cooperation by examining the effect of incident-level variables and neighborhood characteristics on victim cooperation in nonfatal shooting incidents. The sample includes 1,054 nonfatal shooting victims from two Midwestern cities. Results using binary logistic regression suggest that incident and victim characteristics are significantly associated with cooperation, but race conditions the effect of injury severity and motive on cooperation. The willingness to cooperate among Whites is contingent on injury severity while non-White victims do not become markedly more cooperative when confronted with serious injury. Race also moderates the relationship between crime motive and cooperation. This work demonstrates the need to incorporate nonfatal firearm violence into studies of victim cooperation and gun crime more broadly.
