Abstract: This paper presents geo-spatial information concerning access to grocery stores in Dallas County, Texas. A map shows the spatial distribution of neighbourhoods classified according to the number of grocery stores within a one-mile radius. Neighbourhood-level data from the Texas Health and Human Services Commission and US Census reveal distinct demographic characteristics in areas with many versus few grocery stores. No-grocery-store neighbourhoods are predominantly low-income and concentrated in southern Dallas, and African-American neighbourhoods have significantly fewer grocery stores. Disparities in access to nutritious food suggest the possibility of a breakdown in food security, afflicting as many as 400,000 low-income residents. The demographic correlates of grocery store access are analysed in light of economic and behavioural theories of consumer decisions about what to eat and firms| choices of where to locate stores.
