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, Union County fares better than most: just 1.9% of residents live in a low-access tract, below the national share. Still, 0 of the county's 4 tracts meet that threshold, covering about 364 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 Union County compares nationally
Food access in Union County compares favorably nationally: its 1.9% low-access share is lower than the vast majority of the 3,133 U.S. counties with USDA data, higher than only 5% of them (rank #2,968).

What the food-access data shows for Union County
below the national share
An estimated 364 residents, roughly 1.9% of the county's 2010 population, live in one of these low-access areas.
Of those, 138 are also low-income, the group most exposed to genuine food hardship, since limited transportation compounds a limited budget.
The remaining 4 tracts (100.0%) meet the USDA's adequate-access threshold.
None of Union County's tracts meet the USDA low-access threshold, so the county is not flagged for a food-access gap in the 2019 Atlas.
