A food desert is a neighborhood without access to healthy food. Why does this matter? Living in a food desert can lead to higher levels of obesity and other diet-related illnesses such as diabetes and heart disease1.
Walk Score helps you make more informed decisions about where to live, like finding an apartment within walking distance of a grocery store.
Many cities are making access to healthy food part of their general plans. For example, Washington D.C.’s sustainability plan sets a goal of having 75% of residents within a 5 minute walk of healthy food.
But how many people can walk to a grocery store in 5 minutes?
Today, we’re announcing a new ranking of the best and worst U.S. cities for access to food based on our database of local places and our Travel Time API and ChoiceMaps technology.
The Best Cities for Food Access
Our ranking measures access to healthy food by calculating the percent of people in a city who can walk to a grocery store in 5 minutes. The ranking below includes U.S. cities with more than 500,000 residents.

To calculate the percent of residents in a city with access to healthy food we use a variety of data sources and technologies. Our population data and city boundaries come from the U.S. Census. Our list of grocery stores comes from a mix of Google, Localeze, and places added via the Walk Score website. We calculated millions of walking routes for this ranking with our Travel Time API.
Our goal is to only include grocery stores that sell produce. We filter out convenience stores with a combination of algorithmic filters and crowdsourcing. That said, it’s harder than it sounds to get a clean list of grocery stores. If you see a convenience store miscategorized as a grocery store, please click the “Edit place” link and help us improve our data quality.
Our rankings are proximity based and do not include the cost of food. Some studies have shown that shoppers select supermarkets based on price as well as proximity2. For example, people with lower incomes may travel farther to shop at a cheaper grocery store.
Unlike other food desert maps, our maps are dynamic and updated in real-time as our database of underlying grocery stores changes.
Walk Score data is being used by a growing number of cities and planning districts. ”The City of San Jose is using Walk Score data to start tracking performance metrics for our general plan such as how many people can walk to fresh food and parks,” said Joseph Horwedel, Deputy City Manager of San Jose.
Walk Score offers data in spreadsheet or shapefile format for every address in the U.S., Canada, and Australia. We have also aggregated our data for every city and ZIP code in the U.S.
Planners, researchers, and analysts are using Walk Score in a variety of ways:
