Sociodemographic disparities in e-cigarette retail environment: Vape stores and census tract characteristics in Orange County, CA

Research shows disproportionate availability of tobacco retailers in disadvantaged neighborhoods, but little is known about the neighborhood correlates of e-cigarette specialty retailers (i.e., "vape stores"). We compiled addresses for all vape stores in Orange County (OC) (n = 174), CA, using a systematic internet search. Using American Community Survey data, we investigated the spatial structure and census tract correlates of vape store count. 23.4% of census tracts had at least one vape store, and those areas had higher percentage Hispanic population. Multivariate zero-inflated Poisson regressions revealed a higher incidence rate of vape stores in tracts with larger proportions of Hispanics, lower population density, and greater tobacco retailer density, net of other sociodemographic factors and zoning. These results suggest nicotine control initiatives in the age of e-cigarettes must consider the locational strategies of e-cigarette retailers, which are more common in Hispanic communities and areas already marked by tobacco retail activity.
