1. Understanding the Definition of Food Deserts
A food desert is an area, primarily low-income, where many residents lack easy access to affordable and nutritious food, especially fresh fruits and vegetables. It forces residents to depend on processed foods from convenience stores or fast-food outlets, according to the U.S. Department of Agriculture (USDA). These areas are often characterized by a lack of supermarkets and grocery stores offering healthy options.
Food deserts are frequently called “low-income, low-access” areas. The USDA defines a census tract as “low-income” if its poverty rate is 20% or higher, or if its median family income is 80% or less than the statewide or metropolitan area median. A census tract is considered “low-access” if at least 500 people or 33% of the population reside more than one mile from a supermarket or large grocery store in urban areas, or more than 10 miles in rural areas.
2. What is the Difference Between Food Deserts and Food Swamps?
While both terms describe areas with unhealthy food environments, they differ in their focus: food deserts lack access to healthy food, while food swamps are inundated with unhealthy options. Food swamps are areas where fast food outlets, convenience stores, and other vendors of unhealthy food are overly concentrated. Understanding the distinction between these terms is crucial for developing targeted interventions to improve community food environments.
3. Examining the Core Reasons: Why Do Food Deserts Exist?
Food deserts are not natural phenomena; they are the result of systemic racial and economic inequalities. Many food justice advocates argue that the term “food apartheid” is more accurate, as these areas lack access to reasonably priced groceries due to racist policies and practices.
3.1. Historical Context of Racist Policies
Discriminatory housing policies, such as redlining, have historically marginalized communities of color, limiting their access to resources and opportunities, including healthy food options. These policies have created segregated neighborhoods with limited economic development and fewer grocery stores. The legacy of redlining continues to affect food access in many urban areas today, according to the National Resources Defense Council (NRDC).
3.2. Subsidies Favoring Unhealthy Foods
Government subsidies disproportionately support the production of meat and dairy, making these foods more affordable than fresh fruits and vegetables. According to the Food and Agriculture Organization of the United Nations, this incentivizes the overconsumption of animal-based foods, which contributes to health problems and environmental degradation, while fresh produce remains relatively expensive and inaccessible for low-income communities. The organization Food & Water Watch notes that less than 1% of agricultural subsidies go to fresh fruits and vegetables.
3.3. Lack of Investment in Low-Income Communities
Major food retailers are often reluctant to open stores in underserved communities, and they may even move existing stores to wealthier areas, a practice known as “supermarket redlining”. This lack of investment leaves residents with limited options for buying affordable, healthy food. Studies by PolicyLink have revealed that attracting grocery stores to low-income areas requires targeted incentives and community engagement.
4. Unpacking the Causes of Food Deserts in Urban Areas
Food deserts in urban areas result from various interconnected factors, many rooted in historical and ongoing discrimination against marginalized communities. Understanding these causes is essential for developing effective strategies to address food insecurity.
4.1. Scarcity of Food Retailers
Many major food retailers hesitate to establish stores in underserved communities, and they often relocate existing stores to wealthier areas, a practice known as “supermarket redlining.” This trend leaves residents with limited options for purchasing affordable food.
4.2. High Unemployment Rates
Lack of investment in these communities makes it difficult for many residents to find jobs. Residents of food deserts are more likely to be unemployed, further exacerbating poverty and limiting their ability to afford transportation and nutritious food. According to the Economic Policy Institute, targeted job creation programs and workforce development initiatives are crucial for addressing unemployment in these areas.
4.3. Prevalence of Abandoned or Vacant Properties
Food deserts often have higher rates of abandoned or vacant homes than other areas. These empty houses negatively impact the local economy, discouraging food retailers from opening stores in the area. Research indicates that boarded-up vacant homes disproportionately affect predominantly Black neighborhoods, further limiting access to nutritious food.
4.4. Limited Access to Transportation
Inadequate access to transportation is a major factor contributing to food insecurity. Residents who do not own a car, cannot afford public transport, or have mobility issues face significant challenges in traveling to the nearest supermarket or large grocery store. The Transportation Research Board emphasizes the need for improved public transportation and alternative transportation options in underserved communities.
4.5. Pervasive Low Income
Areas with high rates of poverty are more likely to be food deserts. In underserved communities, the cost of healthy food is a significant barrier, making fresh fruits and vegetables seem out of reach for low-income individuals who may feel that fast food and convenience store options are their only choices.
4.6. Population Density and Distribution
Areas facing food insecurity are generally less populated than other areas. As people live further apart, the distance to a food store increases. For some, the nearest supermarket may be more than 20 miles away, posing a significant challenge to accessing healthy food.
5. What are the Effects of Food Deserts?
Access to nutritious food is a basic human need, and unequal access to it has far-reaching consequences, including poor diets, hunger, and health issues.
5.1. Poor Dietary Habits
For many households in low-income, low-access communities, fresh fruits and vegetables are a luxury. Often, the easiest and only option is to consume cheap foods high in fat, salt, and sugar, which lack essential nutrients. The World Health Organization (WHO) has published guidelines emphasizing the importance of a balanced diet rich in fruits, vegetables, and whole grains for overall health and well-being.
5.2. Persistent Hunger
Food insecurity means that millions of people do not know where their next meal will come from. In food-insecure households, adults, particularly women, often skip meals to make their limited food supply last longer, ensuring that children do not go hungry.
5.3. Escalating Health Concerns
Diet and health are closely linked, and residents of food deserts are prone to developing obesity, type 2 diabetes, and other chronic health conditions. Food insecurity can also impact mental health, causing anxiety, depression, and feelings of shame. Studies published in the American Journal of Public Health have highlighted the correlation between food insecurity and mental health issues.
6. Food Deserts: A Statistical Overview
Quantifying the precise number of food deserts is challenging, as it depends on the metrics used. USDA data indicates that, as of 2015, 9,245 of the 72,864 census tracts in the U.S. (12.7%) were classified as low-income and low-access.
6.1. Number of Americans Living in Food Deserts
The USDA estimates that 18.8 million people in the U.S. (approximately 6% of the population) live in low-income tracts more than one mile from a supermarket in urban areas, or more than 10 miles in rural areas. When considering those in low-income census tracts who must travel more than half a mile to reach the closest supermarket, this figure rises to 53.6 million people (about 17% of the population).
6.2. Geographic Concentration of Food Deserts
As of 2015, Mississippi had the highest concentration of food deserts in the U.S., with 31% of its census tracts classified as low-income and low-access. New Mexico followed at 27%, and Arkansas at 26%. However, food insecurity extends far beyond these three states and is present in numerous places across the country, including Chicago, Los Angeles, and New York City.
7. Examples of Food Deserts in Major Cities
Examining specific examples of food deserts in major cities highlights the pervasive nature of this issue and the unique challenges faced by different communities.
7.1. Chicago, Illinois
Many of Chicago’s food deserts are located in South Deering, West Pullman, Pullman, and New City. The total number of supermarkets across the city increased between 2007 and 2014, but this did little to solve food insecurity. Neighborhoods that are predominantly Black have the most limited access to food.
7.2. Los Angeles, California
In the Antelope Valley and South LA, one-third of census tracts are considered not only food deserts but also “food assistance deserts,” according to a 2021 study. These areas lack both reasonable access to supermarkets and local food assistance providers.
Olympia Auset, the founder of SÜPRMARKT, is working to end food insecurity in South LA by providing low-cost, organic produce.
7.3. New York City, New York
Between 2018 and 2020, food insecurity affected an estimated 1.2 million New York City residents. Many of the city’s food deserts are in Black and low-income neighborhoods in East and Central Harlem and North and Central Brooklyn.
8. Potential Solutions for Addressing Food Deserts
Addressing food insecurity requires a multi-faceted approach that includes community-based initiatives, policy changes, and economic empowerment.
8.1. Farmers’ Markets, Mobile Markets, and Roadside Vendors
Farmers’ markets, mobile markets, and roadside vendors can provide communities with the opportunity to purchase fresh, high-quality seasonal fruits and vegetables grown by local farmers. In some neighborhoods, mobile farmers’ markets are delivering food to elderly customers who cannot travel.
8.2. Community Gardens
Urban spaces can be transformed into community gardens, allowing residents and volunteers to grow inexpensive, nutritious, organic vegetables for their families and wider communities. These green spaces can also help people to gain valuable skills and knowledge while building connections with their community and with the food they eat.
8.3. Federal Resources for Low-Income Households
Federal resources can help lift people out of poverty by providing financial support to households and investing in local communities. The Supplemental Nutrition Assistance Program (SNAP), commonly known as food stamps, helps those who are eligible to pay for food. Data from the Center on Budget and Policy Priorities shows that SNAP is effective in reducing poverty and food insecurity.
8.4. Government Policies
Having historically contributed to the problem, government policies must now play a key role in ending food insecurity and building a food system that provides everyone with equal access to fresh fruits, vegetables, and other healthy foods. Proposed solutions include adopting a human rights approach, making financial support more easily accessible to people, and creating more job opportunities.
8.5. Non-Governmental Food Assistance Programs
Without the help of food assistance programs run by charities, non-profit organizations, and local businesses, many families would go hungry. While food pantries and food kitchens are necessary for meeting people’s immediate needs, they are not a long-term solution to the wider problem of food insecurity.
8.6. Surplus Food Sharing
Millions of households struggle to access nutritious food, yet 30 to 40 percent of the food supply in the U.S. goes to waste. Surplus food sharing allows perfectly edible unwanted groceries that are at risk of ending up in landfills to be distributed to families who need them. A number of apps and websites provide a platform for businesses and individuals to share their leftover food with others.
8.7. Grocery Delivery Services
Online food shopping provides a way for people in urban neighborhoods who cannot easily get to a supermarket or large grocery store to buy healthy, inexpensive food and have it delivered to their doorstep. However, home delivery can mean added cost and is not always available in rural areas.
9. Success Stories of Food Desert Transformation
Highlighting successful initiatives that have transformed food deserts into thriving food environments can inspire hope and provide a roadmap for future efforts.
9.1. The Rise of Community Supported Agriculture (CSA)
Community Supported Agriculture (CSA) programs connect local farmers directly with consumers, providing access to fresh, seasonal produce while supporting local agriculture. CSAs have proven effective in improving food access and promoting healthier eating habits in underserved communities.
9.2. Urban Farming Initiatives
Urban farming initiatives transform vacant lots and rooftops into productive agricultural spaces, providing fresh produce and educational opportunities for community residents. These initiatives enhance food security and foster community engagement.
9.3. Policy Changes and Incentives
Policy changes, such as tax incentives for grocery stores to open in underserved areas, can attract retailers and improve food access. These policy interventions create a more equitable food environment and support economic development in marginalized communities.
