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).

USDA data puts St. Clair County's low-access share at 35.7%, above the national share. 23 of the county's 49 census tracts are classified low-access, meaning residents there live far from a supermarket, an area covering about 58,182 people. 7 of those also meet the low-income condition that defines a food desert, home to roughly 19,967 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 St. Clair County compares nationally

Relative to the 3,133 U.S. counties with USDA food-access data, St. Clair County's 35.7% low-access share is elevated, higher than 82% of them and ranked #564 most-affected nationwide.

What the food-access data shows for St. Clair County

above the national share

7 of St. Clair County's 49 census tracts are USDA-designated food deserts, low-income areas where many residents also live far from a supermarket, about 14.3% of all its tracts.

A further 16 tracts are low-access but not low-income, bringing the total low-access tract count to 23.

An estimated 58,182 residents, roughly 35.7% of the county's 2010 population, live in one of these low-access areas.

Of those, 19,967 are also low-income, the group most exposed to genuine food hardship, since limited transportation compounds a limited budget.

The remaining 26 tracts (53.1%) meet the USDA's adequate-access threshold.
