292 million Americans lived in food swamps by 2023
Across two decades and 292 million lives, the American food landscape has shifted not toward emptiness but toward imbalance — fast food proliferating where grocery stores once stood, leaving communities not without food, but without good food. A study spanning 2003 to 2023 reveals that food swamps, neighborhoods overwhelmed by quick-service outlets and starved of fresh groceries, now define nearly nine in ten U.S. census tracts. The burden settles most heavily on rural residents and those without cars, for whom a supermarket ten miles away might as well be a hundred. What the data ask of us now is not diagnosis but will.
- Food swamps have quietly swallowed the American map, expanding from 80% to nearly 89% of neighborhoods over twenty years while 292 million people live surrounded by fast food and little else.
- Food deserts — long the focus of public health concern — barely moved across the entire study period, exposing a harder truth: the crisis is not absence of food retailers, but their overwhelming imbalance toward the unhealthy.
- Rural communities and transit-dependent residents face the sharpest edges of this inequality, where distance without a car becomes an insurmountable wall between a family and a fresh vegetable.
- A brief pandemic dip in food swamps proved illusory — once the acute crisis passed, the underlying drift toward fast-food dominance resumed as if uninterrupted.
- Researchers and public health advocates are now calling for grocery expansion in underserved areas, transit-linked shuttle services, limits on unhealthy outlet proliferation, and serious investigation into whether digital delivery can fill the widening gap.
Over the past twenty years, the American food landscape has undergone a quiet but consequential transformation. A new analysis covering 2003 to 2023 documents it precisely: the share of U.S. census tracts classified as food swamps — neighborhoods where fast-food outlets and quick-service restaurants vastly outnumber grocery stores — climbed from 80 percent to nearly 89 percent. Food deserts, areas with no healthy food retailers at all, barely changed.
By 2023, roughly 292 million Americans lived in food swamps, compared to just 14 million in food deserts. The disparity reveals something counterintuitive: the problem is not primarily the absence of food retailers, but their composition. Grocery stores grow more slowly than fast-food chains, burdened by higher costs and logistical complexity. Warehouse clubs that stock fresh produce often require memberships and locate far from residential areas, adding yet another layer of barrier.
The burden falls hardest on those with the fewest alternatives. Rural residents and people dependent on public transit consistently faced worse access throughout the study period. When researchers measured access by travel time rather than distance alone, the inequalities sharpened — a rural resident might live ten miles from a supermarket with no way to reach it, while an urban bus rider finds a dozen restaurants but no grocery store within a practical journey.
The COVID-19 pandemic briefly interrupted the trend as both healthy and unhealthy retailers closed, but the underlying pattern resumed once the acute crisis passed. Geographically, food deserts concentrated across the North and Great Plains, while food swamps remained widespread everywhere.
The researchers acknowledge limitations — all full-service restaurants were classified as unhealthy due to unavailable menu data, and the study could not capture online grocery delivery's growing role. But the findings point clearly toward action: expanding grocery access in rural and underserved urban areas, developing transit-linked grocery shuttles, evaluating policies that limit unhealthy outlet growth, and investigating whether digital delivery can meaningfully close the gap. The question, the authors suggest, is no longer whether the problem exists — but whether the will to reverse it does.
Over the past two decades, the American food landscape has undergone a quiet but consequential shift. Where grocery stores once anchored neighborhoods, fast-food restaurants and takeout joints have proliferated. A new analysis spanning 2003 to 2023 documents this transformation with precision: the share of U.S. census tracts classified as food swamps—neighborhoods where restaurants and quick-service outlets vastly outnumber grocery stores—climbed from 80 percent to nearly 89 percent. Meanwhile, food deserts, the barren zones with no healthy food retailers at all, barely budged, declining by less than one percentage point over the entire twenty-year period.
The numbers translate to real geography and real people. By 2023, approximately 292 million Americans lived in food swamps. Only 14 million inhabited food deserts. The disparity reveals something counterintuitive: the problem is not primarily the absence of food retailers, but their composition. Unhealthy options have simply outpaced healthy ones. Researchers from the American Journal of Public Health, who conducted the study, attribute this partly to economics. Grocery stores and full-service markets grow more slowly than fast-food chains, hampered by higher operating costs and logistical complexity. Warehouse clubs and department stores that stock fresh produce often locate far from residential neighborhoods and require paid memberships, creating additional barriers.
The burden falls heaviest on those with the fewest alternatives. Rural communities consistently faced worse access to healthy food throughout the study period. So did people dependent on public transportation. When researchers measured accessibility not just by distance but by travel time—how long it takes to reach a grocery store by bus, train, or ferry—the disparities sharpened. A rural resident might live within ten miles of a supermarket but have no practical way to reach it without a car. An urban transit rider might find a dozen restaurants within a twenty-minute bus ride but no grocery store. These structural inequalities compound over time, shaping what people eat and, consequently, their health.
The COVID-19 pandemic briefly interrupted the trend. From 2020 to 2023, the number of food swamps actually declined slightly as both healthy and unhealthy food retailers shuttered. Food deserts ticked upward during this period. But the pandemic's disruption proved temporary. The underlying pattern—the steady encroachment of fast food, the stagnation of grocery access—resumed its course once the acute crisis passed.
Geographically, the problem concentrates in particular regions. By 2023, food deserts were most prevalent across the North and Great Plains, while the mid-Atlantic and West Coast showed lower rates. Food swamps, by contrast, remained widespread everywhere. The researchers acknowledge important limitations in their analysis. They classified all full-service restaurants as unhealthy retailers because detailed menu data was unavailable, though some restaurants certainly serve nutritious meals. The study measured store locations, not actual shopping behavior, food quality, or affordability. It could not fully account for the rise of online grocery delivery, which may reshape access in ways the data cannot yet capture.
The findings point toward policy interventions. Public health agencies and policymakers should prioritize expanding grocery stores in rural areas and underserved urban neighborhoods. Grocery shuttle services, coordinated with public transit systems, could bridge the gap for people without cars. Policies that actively limit the proliferation of unhealthy food outlets deserve evaluation. Researchers should investigate whether digital grocery delivery can meaningfully improve access for those with limited options. The question is no longer whether the problem exists—the data make that clear—but whether the political will and resources exist to reverse it.

Unhealthy food outlets grow more slowly than healthy ones due to financial and logistical challenges, and warehouse clubs often require paid memberships and locate far from residential areas— American Journal of Public Health study authors

Why does it matter that food swamps grew while deserts stayed flat? Aren't both bad?
They're bad in different ways. A food desert is obvious—you have nowhere to buy healthy food. A food swamp is subtler. You're surrounded by food, just not the kind that keeps you well. It's easier to blame someone for poor choices when they're drowning in cheap fast food than when they have no choice at all.
The study mentions the pandemic disrupted things. Did COVID actually help?
Briefly, yes—but only because restaurants closed. When both healthy and unhealthy outlets shut down, the ratio shifted. But that's not a solution. Once things reopened, the old pattern reasserted itself. The pandemic just paused the problem; it didn't solve it.
You mentioned warehouse clubs require memberships. That seems like a small thing.
It's not small if you're poor. A membership fee is a barrier. But more than that, those stores are built for people with cars and disposable income. They're not designed for the neighborhoods where people need them most.
What about delivery apps? Can they fix this?
That's the open question. Delivery might help some people, but it requires a smartphone, a bank account, and internet access. It also costs more. For someone in a rural area with no car and limited income, an app doesn't solve the fundamental problem: there's no grocery store nearby to deliver from.
The study says rural areas got worse. Why?
Rural areas have always had fewer retailers. But over twenty years, the gap widened because fast-food chains expanded into small towns while grocery stores consolidated and closed. A chain restaurant is cheaper to operate in a small market than a full grocery store. Economics favors fast food.
