This article investigates how community vulnerability influences motor vehicle crash (MVC) fatality rates across urban, suburban, and rural areas. Using county-level Social Vulnerability Index (SVI) data and crash fatalities from the NHTSA’s Fatality Analysis Reporting System (2018–2022), the analysis reveals that each one-decile increase in overall community vulnerability corresponds to approximately 12 % higher MVC fatality rates in urban areas, 11 % in suburban areas, and 3 % in rural areas. The study also dissects the SVI into thematic domains—findings show that in urban settings, the “minority status” theme is the strongest predictor of total MVC fatalities, whereas “socioeconomic status” dominates in suburban and rural contexts.

The study highlights that vulnerability-associated risks are notably greater in pedestrian fatalities compared to occupant fatalities, indicating inadequate pedestrian infrastructure in more disadvantaged communities. These results underscore the importance of tailored interventions: in urban areas, emphasis should be placed on equity-informed design and infrastructure upgrades that address pedestrian safety; in suburban and rural environments, programs focusing on reducing socioeconomic disparities (e.g., through access to safer roads, enforcement, and emergency response) may be more effective. Overall, the findings advocate for geographically nuanced strategies to reduce MVC fatalities and promote traffic safety equity.
