Bikeability Disparities in Orange County, California: Intersection of Place and Demographics

Abstract

Active transportation modes such as walking and biking are gaining popularity for their extensive health and environmental benefits, yet scholars know little about how place-based accessibility varies by area sociodemographic composition. This study is among the first to examine sociodemographic disparities (by both race and socioeconomic status) in bikeability while allowing for heterogeneity in disparities. Consideration of bikeability disparities is particularly critical within the framework of urban planning concepts that promote equitable accessibility and reduced dependency on automobiles, such as the 15-minute city. Geographically Weighted Regressions examined associations between census tract-level bikeability (using an index that combines five components), socioeconomic status, and percentage non-White residents (controlling for age of structures in tracts). Findings showed that the strength and directionality of associations between bikeability and race/socioeconomic status varied throughout the county, providing targeted information on where greater concentrations of low socioeconomic status and non-White residents were associated with lower bikeability.
