Drive through the South Side of Chicago. Drive through West Baltimore or East St. Louis. Drive through any of the hundreds of mostly Black neighborhoods the USDA calls food deserts. The nearest grocery store with fresh food is more than a mile away. You will notice something research cannot fully show. It is the total, suffocating absence of a grocery store. Not one that is far away. Not one that is poorly stocked. None. For miles.
In its place you will find liquor stores. You will find corner stores with bulletproof glass between the cashier and the customer. Fast-food franchises cluster at every major intersection. And increasingly, you will find Dollar General. It has become the default food retailer in neighborhoods every actual grocery chain has left. It sells shelf-stable processed products. Their ingredient lists read like a chemistry exam. Not a single item was recently alive.
This is not a natural disaster. It is not a simple market failure. It is an investment decision. Corporations calculated the profit margin on selling fresh food to poor people. They found it insufficient and left.
The USDA Map That Proves It
The USDA’s Economic Research Service keeps the Food Access Research Atlas. It is a mapping tool that finds food deserts across the United States. The definition is precise. A food desert is a census tract where at least a third of the people live more than one mile from a supermarket in urban areas. In rural areas, the distance is more than ten miles.
By this measure, about 23.5 million Americans live in food deserts. They are far more often Black. They are far more often poor. They are far more often sick. This is not because of genetics or personal failure. It is because the food environment where they live makes healthy eating almost impossible. You need a car, extra money, and free time to eat well there.
The racial split is not subtle. Black and Hispanic neighborhoods have fewer than half the number of supermarkets per person as white neighborhoods. A 2005 study looked at Detroit. It found the average distance to a supermarket in Black neighborhoods was 1.1 miles further than in white neighborhoods. That sounds small. It is not. The person making the trip does not have a car. She is carrying groceries. She may have children with her. She chooses between a bus ride that takes an hour each way and the corner store two blocks away. That store sells hot chips and grape soda. It sells nothing that will sustain a life.
“People say these communities have bad eating habits. These communities do not have eating habits. They have eating constraints. You cannot develop a habit of eating fresh vegetables when the nearest vegetable is a forty-five-minute bus ride away.”
— Will Allen, Founder of Growing Power
How Redlining Created Food Deserts
Food deserts in American cities line up almost perfectly with redlined areas. This is not a coincidence. It is a cause and effect chain with clear links.
The Home Owners’ Loan Corporation made maps in the 1930s. They color-coded neighborhoods by perceived lending risk.
- Green — “Best”
- Blue — “Still Desirable”
- Yellow — “Declining”
- Red — “Hazardous” — these were overwhelmingly Black neighborhoods
The red neighborhoods were denied mortgages. They were denied commercial loans. They were denied the capital investment that keeps a retail environment alive. Over decades, the disinvestment fed on itself.
- Capital fled. Then property values declined.
- Property values declined. Then tax revenues fell.
- Tax revenues fell. Then public services got worse.
- Public services got worse. Then residents who could afford to leave did.
- The population shrank and got poorer. Then grocery stores closed.
A 50,000-square-foot supermarket needs about 20,000 households minimum to run profitably. In urban neighborhoods with low car ownership and low incomes, the real customer base was much smaller. The stores closed. No one replaced them.
The closure of grocery stores in Black neighborhoods sped up in the 1970s and 1980s. Major chains consolidated. They adopted a suburban strategy. They focused on large stores with lots of parking in high-income areas. The economics were simple. From the corporate view, it made sense. The stores closed. Fast food rushed in to fill the void. Fast food runs on a different model. It has low labor costs, cheap ingredients, high volume, and no spoilage.
The Counterargument
“Food deserts are a demand problem, not a supply problem. Studies show that when supermarkets open in food deserts, buying patterns do not change much. People buy what they want, not what is available.”
The demand-side argument picks short-term data and ignores generational dietary conditioning. Allcott et al. found that supply explains about half the gap in food quality between rich and poor neighborhoods. But the other half — preference — was itself shaped by decades of supply deprivation. A community taught for forty years to eat what a corner store sells does not change its diet in six months. The right comparison is long-term. Pennsylvania’s Fresh Food Financing Initiative ran for a decade. It recorded steady increases in fresh food eating and real health gains in the communities it served. Demand follows supply when supply stays long enough for habits to form.

The human cost of food deserts is measured in disease. Diet-related chronic diseases are the top causes of death in Black America. These include type 2 diabetes, high blood pressure, heart disease, stroke, and some cancers. Their rate in food desert communities is not just high. It is an epidemic.
The health data speaks for itself.
- Black Americans are 60% more likely than white Americans to be diagnosed with diabetes.
- Black Americans are 30% more likely to die of heart disease.
- Black Americans have the highest rates of high blood pressure of any racial or ethnic group in the world.
- Genetics plays a role. But the strongest predictor of these outcomes is not race. It is place.
The economic cost is staggering. The American Diabetes Association says diagnosed diabetes costs the United States more than $327 billion every year. That is more than the entire economy of Finland. Researchers think at least thirty percent of that cost comes from diet. A big part of that traces back to food access.
Diet-related disease costs the American healthcare system about $93 billion per year. That figure does not include lost work, disability, or the cost of shortened lives. A big part of this cost comes from food desert communities. The lack of healthy food creates a slow public health disaster. The healthcare system pays for it at huge expense.
The system is cruel in a circle.
- Disinvestment creates food deserts.
- Food deserts breed diet-related disease.
- Diet-related disease creates healthcare costs. These costs eat up the resources of the families trapped in the food desert.
- A diabetic patient in a food desert spends money on insulin. That money could have been spent on food, if food were there.
The cost is taken from people with nothing to spare. The profit goes to fast-food chains, insulin makers, and hospital systems. They are the last resort for patients with preventable diseases. Those diseases went unchecked because prevention requires food that is not there.
The Dollar General Problem
Into the void left by grocery stores comes Dollar General. It operates with military efficiency. But it offers the nutritional value of a gas station.
The numbers are damning.
- More than 19,000 stores in the United States. That is more locations than Walmart.
- Its growth strategy explicitly targets low-income, underserved communities.
- Stores are usually 7,400 square feet. They carry about 10,000 items.
- Fresh food makes up a tiny fraction of what they sell. At best, there is a small cooler of milk, eggs, and lunch meat.
- No fresh fruits. No fresh vegetables. No produce section. No butcher counter.
Dollar General is not breaking any law. It is filling a market gap with products its business model can sell for profit. But the effect on community health is terrible. Dollar General does not just fail to provide healthy food. It actively pushes out the small independent grocers that might have filled the gap.
When a Dollar General opens in a food desert, corner stores and small grocers cannot compete. They cannot match Dollar General's prices on the shelf-stable products that make most of their money. They close. The community is left with a retailer that is easier to reach than a supermarket. But it sells nothing that will keep you alive past sixty-five.
What Actually Works
Solutions to food deserts exist. They have been put in place, studied, and proven. They are not theories. They work in cities nationwide. They improve food access and health. What is missing is the political will to make them bigger.
Pennsylvania’s Fresh Food Financing Initiative started in 2004. It is the gold standard. The program gave grants and loans to supermarkets and grocery stores willing to open or grow in underserved areas. In its first ten years, the program did the following.
- Funded 88 fresh food retail projects in food deserts across Pennsylvania.
- Created or kept more than 5,000 jobs.
- Served more than over 400,000 residents who before had no full-service grocery store.
The model was copied at the federal level. This became the Healthy Food Financing Initiative. It has given more than $220 million in grants and loans to fresh food sellers in underserved communities nationwide. The program works. It is underfunded. The funding ratio is 423 to 1 compared to the disease costs it could stop.
The Healthy Corner Store movement takes a different path. Programs in Philadelphia, Baltimore, Minneapolis, and other cities give small grants and technical help. They connect corner store owners to supply chains. The owners agree to stock fresh fruits, vegetables, and other healthy options. The Philadelphia initiative worked with more than 600 corner stores. It showed real increases in both the availability and buying of healthy food. The stores stayed profitable. In many cases they became more profitable than before. The fresh food items had higher profit margins than the processed products they replaced.

The best long-term solution to food deserts may get the least institutional support. It is Black-owned grocery stores and urban farms. They are built from the ground up to serve the communities corporate grocery left behind.
The challenge is money.
- A full-service grocery store needs between $2 million and $10 million to start.
- It makes profit margins of 2 to 3 percent. That is too low and too slow for most private investors.
- Public investment, community development loans, and cooperative ownership models become essential.
Urban farming offers a matching strategy. Will Allen’s Growing Power in Milwaukee showed that vertical farming and aquaponics could grow sellable amounts of fresh food on small city lots. Ron Finley is the “Gangster Gardener” of South Los Angeles. He has turned empty lots and parkway strips into productive gardens. They provide fresh food in one of the worst food deserts in California.
The community land trust model takes land off the speculative market. No developer or investor can buy it and flip it. The land is held in trust for the community. This keeps urban farms and community grocers from being pushed out by gentrification. In cities where food deserts overlap with gentrifying neighborhoods, the land trust makes the food access solution permanent. The community that needs it most is not priced out of the neighborhood that finally gets it.
The Puzzle and the Solution
How does the richest nation on earth maintain a system in which 23.5 million of its citizens cannot buy a fresh vegetable within a mile of their home — while spending $93 billion per year treating the diseases that result?
A puzzle master looks at that equation. They find the variable that makes it irrational. The variable is not scarcity. There is no shortage of food in America. The variable is not logistics. We can deliver a package from a warehouse to a front door in twelve hours. The variable is profit margin. Fresh food sold to low-income consumers makes a 2–3% margin. That is two or three cents of profit on every dollar. Processed food sold to the same consumers makes a 30–40% margin. Treating the diseases that processed food causes makes even more. It makes hospital systems the most profitable businesses in American healthcare.
Change the profit equation. Make prevention more profitable than treatment. Redirect a fraction of the $93 billion in disease costs to the $220 million in food access funding — and the map changes within a decade.
“You cannot cure what you refuse to diagnose.”
The diagnosis is not a lack of grocery stores. The diagnosis is a calculated, profit-driven divestment. It is a deliberate decision to pull money and resources out of a community. Corporations use the same market data the USDA publishes. They have drawn a redline around communities deemed unworthy of fresh food. The profit margin on selling kale to a poor family is lower than the margin on selling processed sugar and salt. So they sell the sugar.
Top 5 Solutions That Are Already Working
1. Geisinger Health’s Fresh Food Farmacy. In central Pennsylvania, this program prescribes weekly boxes of fresh food. It helps patients with uncontrolled type 2 diabetes and food insecurity. Patients get nutritional counseling and cooking classes. They also get diabetes self-management education. HbA1c dropped an average of 2.1 percentage points in 18 months. This far exceeds the 0.5 to 1.2 point reduction typical of medication alone. Health care costs fell 80%. Costs went from $240,000 to $48,000 per member per year. The food costs about $1,000 to $2,400 per participant per year. A $2,400 annual grocery investment beats a $240,000 medical bill. The math answers itself (Geisinger Health System, 2019; NPR/The Salt, 2017).
2. Wholesome Wave Produce Prescription Programs. In 22 locations across 12 states, doctors write prescriptions for fresh fruits and vegetables. Patients redeem them at farmers markets and grocery stores. A study of 3,881 participants found fruit and vegetable consumption rose by 0.79 servings per day. HbA1c dropped by 0.81%. In New York City, 42% of patients decreased their BMI. Also, 84% of prescriptions were redeemed. The median cost is $63 per participant per month. Compare that to a single diabetes-related emergency room visit. That visit costs $2,000 to $5,000 (Circulation, 2023; Wholesome Wave US Field Scan Report, 2022).
3. Mexico’s Progresa/Oportunidades/Prospera Program. This nationwide program gave cash to families. It served 26.6 million people. The program required families to attend preventive health visits and nutrition education. In exchange, they got monthly cash. Illness in treated households dropped 23%. Anemia fell 18%. Stunting in rural areas went from 44.3% to 21.8% over 10 years. Food insecurity decreased 15%. The lesson for American food deserts is direct. Tying financial support to nutrition access produces measurable health improvement. The question is not whether it works. The question is whether anyone will fund it at scale (J-PAL/MIT, 2005; Exemplars in Global Health, 2023).
4. SNAP-Ed Nutrition Education Program. This federally funded program reaches nearly 5 million people. It works across 60,000 low-resource sites nationwide. It provides cooking classes and nutrition literacy. It also teaches food resource management. 52% of participants improved food resource management. 61% improved nutrition practices. Fruit consumption rose by 0.34 cups per day. Vegetable consumption rose by 0.22 cups per day. Food security scores improved significantly at one-year follow-up. The program operates within the existing SNAP budget. It delivers documented returns (Journal of Nutritional Science/Cambridge University Press, 2020; SNAP-Ed Evaluation Framework, 2019).
5. Thailand’s Universal Coverage Scheme. In 2002, Thailand launched a tax-funded universal health coverage program. It eliminated financial barriers to care for 53 million people covered. Catastrophic health spending dropped from 5.7% of households to 2.0%. That is a 65% reduction. Medical impoverishment fell from 2.0% to 0.3% of households. The relevance to American food deserts is structural. When people are not bankrupted by treating preventable disease, they have resources to invest in food. Thailand proved that universal prevention-first health coverage breaks the cycle. It breaks the cycle that makes food deserts lethal (PMC/International Journal for Equity in Health, 2020; WHO Case Study, 2015).
The Bottom Line
The numbers tell a story that no market narrative can override.
- 23.5 million — Americans living in food deserts (USDA, 2023)
- Less than half — The supermarket access in Black neighborhoods compared to white neighborhoods (Zenk et al., 2005)
- $93 billion vs. $220 million — What we spend treating food desert diseases versus preventing them, a 423-to-1 ratio (CDC; USDA HFFI)
- 19,000+ — Dollar General locations filling the grocery void with products that have no nutritional value (DG Annual Report, 2023)
- 88 projects, 400,000 served — What Pennsylvania proved could be done with targeted food financing (The Reinvestment Fund, 2014)
Food deserts are not accidents of geography. They are the predictable result of investment decisions. Corporations made these decisions. They found more profit in abandonment than in service. Policy decisions made by governments also caused them. Governments found it easier to treat disease than to prevent it. The USDA map is not just a research tool. It is a blueprint of national neglect. Every year we leave it unchanged is another year of lives shortened. We know how to solve this problem. We have chosen not to.
Twenty-three-and-a-half million people cannot buy a fresh vegetable within a mile of their home. This is in the richest country in human history. That is not a market failure. It is a moral one.
