CSDE Affiliate Dafeng Xu (Evans School of Public Policy and Governance) recently published a research article in the Journal of Planning Education and Research titled, “Social Networks and Transportation Efficiency: Ethnic Concentration and Carpool Commutes Among Hispanic Workers in the United States.” Hispanic workers are more likely than non-Hispanic white workers to carpool, a commuting mode that is more affordable but also more time-consuming than driving alone. Using 2019 five-year American Community Survey data, Xu finds that Hispanic commuters are more likely to carpool in areas with larger Hispanic populations. Ethnic concentration is also linked to efficiency: although carpoolers still have longer commutes than solo drivers, this added time cost shrinks across all socioeconomic groups as the local Hispanic share rises. The findings suggest that policymakers can improve commuting efficiency by supporting community-based programs that promote carpooling in minority neighborhoods.
