Low access = living more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket. Food deserts add a low-income condition (USDA LILA, 1-and-10-mile measure).

Johnson County's low-access share sits near the national share, at 8.6% per the USDA Atlas. 6 of the county's 24 census tracts are flagged low-access, covering roughly 11,215 residents who live far from a supermarket. 3 of those also meet the low-income condition that defines a food desert, home to roughly 3,091 low-income residents.

How the USDA defines low-access and food-desert tracts

The USDA measures food access by distance to the nearest supermarket. A census tract is "low-access" when a meaningful share of residents live more than one mile from a supermarket in urban areas, or more than ten miles in rural areas. A tract becomes a "food desert" only when it is both low-access and low-income, because distance is far harder to overcome for households without a car or a cushion in the budget. Counts on this page are aggregated from the tract level, where the federal data is actually published, so a single county figure can hide neighbourhoods that are much better or much worse served than the average. Distance also does not capture everything that shapes whether a family eats well: the presence of a full-service grocer rather than a convenience store, public transit, food pantries, and the price and quality of what is on the shelf all matter beyond the radius the Atlas can draw.

How Johnson County compares nationally

Johnson County lands in the middle of the national distribution: a 8.6% low-access share that beats 17% of the 3,133 U.S. counties with USDA data (rank #2,597).
