What is the association of eviction with firearm violence in Chicago, Illinois, and how does eviction moderate the association between collective efficacy and firearm violence?In this cross-sectional study of 13 916 Chicago residents, a 1% increase in the census tract eviction rate was associated with 2.66 additional shootings within 1000 feet of the individual’s home. Eviction was also a significant moderator of collective efficacy—a community’s belief in their ability to achieve a shared goal—augmenting associations of low collective efficacy with firearm violence.These findings suggest that eviction is a possible structural disadvantage associated with firearm violence in Chicago.
