Socioeconomic inequality is a critical challenge our society faces, as its mitigation enhances group cohesion, social mobility, and long-term economic growth. Traffic crashes may be viewed as a domain that is marginally affected by socioeconomic inequality. Prior studies, however, have reported more fatalities and injuries in poorer neighborhoods. This leads to research questions about socioeconomic disparities, particularly on Virginia roads. To address the research question, this study analyzed large-scale panel data in two phases. The panel data for Phase 1 focused on county level analysis. The data consisted of 1,064 observations between 2013 and 2020 and used four heterogeneous big data sources: Virginia crash data, Virginia traffic vehicle miles traveled data, the American Community Survey, and County Health Rankings and Roadmaps.

The analysis of this project’s empirical results indicates:
