Selective Daily Mobility Bias in the Community Food Environment: Case Study of Greater Hartford, Connecticut
In this paper, we aim to confirm the existence of the selective daily mobility bias (SDMB) by systematically exploring the large-scale GPS-based restaurant-visit patterns in the Greater Harford region, Connecticut. Our primary results demonstrate that (1) most restaurant customers originate from areas outside of the census tract where the restaurant is located, and (2) restaurants located in socially vulnerable areas attract more customers in total, more customers from local areas, and more customers from other socially vulnerable areas. These results confirm the relevance of the SDMB to the community food environment, and suggest ways that the SDMB can be moderated by an uneven socio-economic landscape.
