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).
By the USDA's measure, Poweshiek County fares better than most: just 6.1% of residents live in a low-access tract, below the national share. Still, 1 of the county's 5 tracts meet that threshold, covering about 1,158 people who live far from a supermarket, and none of them meet the low-income condition that would additionally classify them as food deserts.
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 Poweshiek County compares nationally
Food access in Poweshiek County compares favorably nationally: its 6.1% low-access share is lower than the vast majority of the 3,133 U.S. counties with USDA data, higher than only 12% of them (rank #2,760).

What the food-access data shows for Poweshiek County
below the national share
A further 1 tract is low-access but not low-income, bringing the total low-access tract count to 1.
An estimated 1,158 residents, roughly 6.1% of the county's 2010 population, live in one of these low-access areas.
