Commercial density, residential concentration, and crime: Land use patterns and violence in neighborhood context

Drawing on Jacobs's (1961) and Taylor's (1988) discussions of the social control implications of mixed land use, the authors explore the link between commercial and residential density and violent crime in urban neighborhoods. Using crime, census, and tax parcel data for Columbus, Ohio, the authors find evidence of a curvilinear association between commercial and residential density and both homicide and aggravated assault, consistent with Jacobs's expectations. At low levels, increasing commercial and residential density is positively associated with homicide and aggravated assault. Beyond a threshold, however, increasing commercial and residential density serves to reduce the likelihood of both outcomes. In contrast, the association between commercial and residential density and robbery rates is positive and linear. The implications of these findings for understanding the sources of informal social control in urban neighborhoods are discussed.
