This study presents a conservative image-based w…

• Population-level measures of perceived food access reveal barriers beyond geographic proximity

  Teresa Groton, Benjamin rachunok · 14 septembre 2026

  Food access is multidimensional, but population-level measurement still relies heavily on geography because perceived dimensions of access are difficult to measure at scale. Here, we use 25,125 Google Maps reviews from 49 grocery stores in Raleigh, North Carolina, to measure five dimensions of food …
