Around the U.S. and in Oregon, people and organizations traditionally involved with separate elements of the food system are coming together to tackle challenges related to health, environment, and the economy, as part of the “community food systems” movement. Bringing people and organizations together to evaluate and change aspects of the food system requires developing a common understanding of issues and shared goals. The Community Food Systems Indicators provide an integrated dataset that supports these efforts.
People need access to healthy and affordable food. Access can be measured in many different ways; the USDA creates the low-income and low-access measure (LI/LA) by census tract, using income and distance to supermarkets. This information is used by governments, community planners, public health officials, and researchers to plan programs and target resources that increase access and improve diets and health.
While supermarkets are the primary way many people access food, the number of farmers markets has increased, which can provide important access to some food items. Nutrition and public health researchers have suggested that farmers markets and other direct-to-consumer venues can increase healthy food access in rural communities (see “For more information,” Johnson et al.). We examined 2018 data for Oregon to see if farmers markets currently fill some of the gaps left by supermarkets.
Maybe. Many parts of Oregon do not have a farmers market. There are 12 LI/LA areas with a farmers market and most of these are in urban areas (see Table 1). Farmers markets are organized for a variety of reasons and meet multiple needs, such as the Lents International Farmers Market in Portland that was founded to improve food access.
We can also visually examine the distribution of low income and low access to supermarket census tracts with the known locations of some of the farmers markets across the state (see Figure 1).
Efforts to expand access to fresh, healthy foods are important statwide. Farmers markets may offer one opportunity to increase access, especially in areas with the lowest access to supermarkets. Other factors to consider include the suitability of the area for local food production and the density, ability to travel, and spending capacity of the area’s population.
What else matters?
This analysis uses data from the USDA ERS Food Access Research Atlas to visualize low-income census tracts with low access to supermarkets* and how, in 2018, these overlap with the distribution of farmers markets that are members of the Oregon Farmers Markets Association (OFMA). Not all farmers markets are members of OFMA. The Rural Communities Explorer website uses a different data source, the USDA’s Farmers Markets directory, which lists an additional 65 markets, or 168 in total. However, many of these markets are no longer open. We use the OFMA list to focus on markets that are currently in operation.
Census tracts are designated as low income and low access (LI/LA) following these definitions:
– Proportion of the population based on poverty rate or median household income compared to the state or metropolitan area
– Households that are more than ½ mile from the nearest supermarket and have no access to a vehicle; or
– Households that live more than 20 miles from the nearest supermarket regardless of vehicle access
About 14% of Oregon’s census tracts are considered LI/LA under this definition, while 30% of Oregon’s census tracts are considered LI/LA under another definition*.
