Food Deserts in America: Why Access to Healthy Food Is Still a Crisis

A food desert is defined by the USDA as a low-income area where a substantial portion of residents lives more than one mile from a supermarket in an urban area, or more than 10 miles in a rural area. By this measure, approximately 23.5 million Americans — including 6.5 million children — live in food deserts. They have jobs. They have money. They simply cannot access nutritious food at reasonable cost because the infrastructure that makes food access possible does not exist in their communities.

The food desert is not a natural phenomenon. It is the product of specific economic, policy, and historical decisions — about where to build grocery stores, where to invest in transportation infrastructure, and whose communities are considered commercially viable by the retail food industry. Understanding food deserts requires understanding those decisions and who made them.

What Life in a Food Desert Actually Looks Like

In a food desert, the landscape of food retail is typically characterised by: dollar stores selling heavily processed, shelf-stable foods; fast food restaurants; convenience stores with minimal fresh produce; and liquor stores. Fresh vegetables, fruit, whole grains, and quality protein are either unavailable or available only at prices that make them economically inaccessible to low-income residents.

The practical experience of food desert living for a family without a car — a significant portion of low-income urban households — involves bus journeys of 45 minutes to an hour each way to reach a supermarket, carrying groceries on public transport, and making purchase decisions shaped not by nutritional preference but by what can be carried, how quickly it will spoil, and how much it costs. Convenience and dollar stores fill the gap, providing calories at low prices but nutritional value that is systematically insufficient for long-term health.

The health consequences are visible in the chronic disease data. Communities that have been food deserts for decades show elevated rates of type 2 diabetes, cardiovascular disease, obesity, and hypertension — conditions that are preventable with adequate nutrition but that become management rather than prevention challenges when nutritious food is absent.

Where Food Deserts Exist and Why

Food deserts are not randomly distributed. They are concentrated in:

• Low-income urban neighbourhoods, particularly in predominantly Black and Latino communities
• Rural areas with dispersed populations and limited retail infrastructure
• Native American reservations and tribal lands
• Formerly industrial communities where economic decline has eliminated retail infrastructure

The pattern reflects retail industry economics: grocery stores require a customer base with sufficient purchasing power to justify the investment. In low-income communities, thin margins, theft concerns, and insurance costs historically led major grocery chains to disinvest or not invest in the first place. The resulting absence of grocery retail is not a market failure in the neutral sense — it is a rational response to a market structure that systematically undervalues low-income communities.

The racial dimension is not incidental. Historical residential segregation — enforced through redlining, restrictive covenants, and discriminatory mortgage policies — created the geographic concentration of poverty that underlies food desert geography. The food desert is, among other things, a consequence of housing discrimination.

The Dollar Store Problem

Dollar stores have expanded dramatically in low-income American communities over the past two decades. Dollar General and Family Dollar together operate over 35,000 stores, many of which are in communities without supermarkets. While these stores provide affordable shelf-stable food and household products, research consistently shows that their expansion correlates with reduced fresh food availability — in some cases, dollar stores have actively blocked the entry of grocery stores by purchasing sites and offering leases that include restrictions on food retail competition.

Communities that have tried to attract full-service grocery stores frequently report that the presence of multiple dollar stores reduces the economic viability of the proposed grocery operation — creating a feedback loop that entrenches the food desert.

Community Solutions: What Works

• Community gardens and urban farms — producing fresh produce in communities where retail access is limited
• Mobile farmers markets — bringing fresh produce directly into food desert neighbourhoods on regular schedules
• Community-owned grocery cooperatives — food retail owned by and accountable to the community rather than external investors
• SNAP incentive programmes — doubling SNAP purchasing power at farmers markets, making fresh produce economically accessible
• Food recovery and redistribution — capturing surplus food from restaurants, supermarkets, and producers and redirecting it to community distribution points in food deserts

Food recovery — capturing surplus and imperfect food before it becomes waste — is one of the most effective and scalable responses to food access inequality. Our post on zero-waste cooking and how recovered food feeds communities explains how this approach works in practice at A Better Life Foundation.

And understanding the food desert crisis is incomplete without understanding the deeper connection between food access, poverty, and community health. Our post on how nutritious meals break the cycle of poverty examines why food access is a precondition for every other dimension of upward mobility.
