The most severe outcome of intimate partner violence (IPV) is IPV-related homicide. Access to affordable housing may both facilitate exit from abusive relationships and reduce financial stress in intimate relationships, potentially preventing IPV-related homicide. We examined the association of the availability of rental housing through the Low-Income Housing Tax Credit (LIHTC) program, a federal program providing tax incentives to support the development of affordable housing, with IPV-related homicide and assessed whether this association differed by eviction rates at the state-level. We used 2005-2016 National Violent Death Reporting System, LIHTC Property, and Eviction Lab data for 13 states and compared the rate of IPV-related homicide in state-years with ≥30 to state-years with <30 LIHTC units per 100,000 population, overall and stratified by eviction rates. We conducted analyses in fall 2020. Adjusting for potential state-level confounders, the rate of IPV-related homicide in state-years with ≥30 LIHTC units per 100,000 population was lower than in state-years with <30 LIHTC units per 100,000 population (RR = 0.89, 95% CI 0.81, 0.98). The reduction in the rate of IPV-related homicide was slightly larger in state-years with higher eviction rates (≥3500 evictions per 100,000 renter population; RR = 0.83, 95% CI 0.74, 0.93) compared to state-years with lower eviction rates (<3500 evictions per 100,000 renter population; RR = 0.91, 95% CI 0.81, 1.03). Overall, at the state-level, increased availability of affordable housing through the LIHTC program was associated with lower rates of IPV-related homicide. Increasing the availability of affordable housing may be one tool for preventing IPV-related homicide.
亲密伴侣暴力（IPV）最严重的后果是与 IPV 相关的杀人。获得负担得起的住房不仅可以促进人们脱离虐待关系，还可以减轻亲密关系中的经济压力，从而有可能防止与 IPV 相关的杀人事件。我们研究了通过低收入住房税收抵免（LIHTC）计划获得出租住房的情况，该计划是一项为支持经济适用房开发提供税收优惠的联邦计划，与与 IPV 相关的杀人事件之间的关联，并评估了这种关联是否因州一级的驱逐率而异。我们使用了 2005-2016 年全国暴力死亡报告系统、LIHTC 物业和驱逐实验室的数据，对 13 个州进行了比较，并将州年与每 10 万人中至少有 30 个 LIHTC 单位的州年与每 10 万人中少于 30 个 LIHTC 单位的州年进行了比较。我们在 2020 年秋季进行了分析。在调整了潜在的州一级混杂因素后，每 10 万人中至少有 30 个 LIHTC 单位的州年的与 IPV 相关的杀人率低于每 10 万人中少于 30 个 LIHTC 单位的州年（RR=0.89，95%CI 0.81，0.98）。在驱逐率较高的州年（每 10 万租户中有 3500 次以上的驱逐；RR=0.83，95%CI 0.74，0.93），与驱逐率较低的州年（每 10 万租户中有 3500 次以下的驱逐；RR=0.91，95%CI 0.81，1.03）相比，与 IPV 相关的杀人率降低幅度略大。总的来说，在州一级，通过 LIHTC 计划增加经济适用房的供应与较低的与 IPV 相关的杀人率有关。增加经济适用房的供应可能是预防与 IPV 相关的杀人事件的一种手段。
