Although the relationship between neighborhood characteristics and collective efficacy is well established in urban populations with community samples, it is unclear if this relationship holds in rural areas. The current study fills this gap by assessing the perceptions of adolescents from nonurban areas to examine the relationships between neighborhood characteristics and collective efficacy in areas with lower population density. Our sample comprised 402 late adolescents attending a Midwestern university (average age 19.1 years). Consistent with previous studies using urban neighborhoods, we found that higher concentrated disadvantage was related to lower levels of social cohesion, regardless of population density. However, neither residential stability nor concentrated immigration was predictive of social cohesion. None of the neighborhood characteristics significantly predicted social control, after controlling for population density. (Contains 1 table.)
