USDA Economic Research Service, Food Access Research Atlas (2019), population-weighted · Census ACS 2024 context

The USDA Food Access Research Atlas evaluates every census tract in Iowa against the same rule used nationwide: a tract is low-access when many residents live more than one mile from a supermarket in urban areas, or more than ten miles in rural areas. Across 99 counties and 3.2M residents, Iowa's population-weighted low-access share is 20.0%.

A tract becomes a food desert only when its low-access residents are also low-income. That applies to 85 tracts in Iowa, home to roughly 173K low-income, low-access residents. SNAP participation across the state averages 8.8% of households, and 5.4% of households have no vehicle, the transport gap that turns distance into a real barrier. The county table below is sorted with the highest low-access share first, so the top rows are where distance, income, and vehicle gaps most consistently overlap.
