Firearm homicide and suicide deaths for 2014 were examined in Harris County, Texas, for spatial variation and socio-economic correlates. Higher firearm homicide rates were found closer to central Houston than firearm suicide rates. Local hot spots were identified for both types but overlapped at only two locations. A Poisson–Gamma–Exposure regression model showed the homicide rate was associated with higher percentages of persons who are Black, aged 15 to 29 years, and living in poverty whereas the suicide rate was associated with a higher percentage of persons of non-Hispanic White ethnicity. Firearm policies that reduce homicides may also reduce suicides.

调查了德克萨斯州哈里斯县2014年枪支凶杀和自杀死亡的空间变异性和社会经济相关性。发现靠近休斯顿市中心的枪械凶杀率高于枪械自杀率。两种类型都发现了局部热点，但仅在两个位置重叠。Poisson-Gamma-Exposure回归模型显示，凶杀率与年龄在15至29岁，生活在贫困中的黑人比例较高有关，而自杀率与非西班牙裔白人中较高的比例有关种族。减少凶杀的枪支政策也可能减少自杀。
