Neighborhood Heat Exposure and Urban Gun Violence


This study will assess whether variations in daily temperature generate different effects on gun violence risk in cities and neighborhoods that experience heat more severely.




This project seeks to inform prevention efforts by identifying factors that influence the association between daily temperature and gun violence.


Use data on daily temperatures, social/physical environment variables, and fatal/non-fatal gun violence incidents from a large sample (n > 100) of U.S. cities, to explore the modifiers of heat effects (1) between cities and (2) within cities.


Exposure to urban heat is increasing with climate change, and disproportionately affects urban communities that experience greater social deprivation. This work will determine whether the effects of daily temperature on urban gun violence are most severe in cities and neighborhoods with the greatest heat exposure.
