This study seeks to contribute to research on the patterning and stability of code of the street beliefs. We describe trajectories of street code beliefs from late childhood to emerging adulthood and investigate social factors that influence membership in and distinguish between trajectories.

Using six waves of panel data from the Family and Community Health Study, group-based trajectory models were estimated to describe developmental patterns of street code beliefs from age 10 to 26. Correlates of street code beliefs, including racial discrimination, parenting practices, and neighborhood crime, were used to predict trajectory membership.

Analyses identified five distinct trajectories of street code beliefs. Four trajectories were largely stable across the study period; however, one group, comprised of 12 percent of the sample, dramatically declined in beliefs. Being male and experiencing racial discrimination significantly distinguish between all of the trajectories. Parental monitoring and perceptions of neighborhood crime differentiate between the declining trajectory and the stable trajectories.

Findings provide insights into the developmental patterns and correlates, of street code beliefs. Results suggest beliefs are malleable but remain largely stable and underscore the need for more nuanced, longitudinal approaches to the code of the street.
