Food Access Maps

Food insecurity is a complex issue. That's why GIS mapping can help visualize the issue of food insecurity across Jefferson County and the Denver Metro region. Through this series of interactive maps, you can visualize areas that lack adequate access to healthy, affordable food or have a high concentration of fast food options. You can also see the locations of important local resources, such as Community Supported Agriculture programs and food pantries, and their proximity to high needs areas.

Explore the interactive maps below and use the data for your own work.  

100 Miles from Jeffco

This interact100 Miles from Jeffco Food Access Map Opens in new windowive map is a simple visualization showing linear distance and the driving distance along road networks from the geographic center of Jefferson County. This map was generated in response to a discussion at the Food Policy Council about “buy local” policies and what geographic areas, and therefore local food sources, would be considered within 100 miles of Jefferson County.

At-Risk Index (ACS 2015-2019)

This map depicts an At-Risk index based on these socioeconomic At-Risk Index Map Opens in new windowindicators:

  • Median household income
  • Percentage households below poverty
  • Median value of owner-occupied housing units
  • Percentage of housing units that are owner occupied
  • Percentage of adults 25 years and older with complete high school
  • Percentage of adults 25 years and older with complete college
  • Percentage of persons 16 and older in management, business, science, arts occupations
  • Percentage Unemployed

Each of these indicators is compared to the state average. Any indicator falling below the state average (or above in the case of poverty) is considered at risk for that factor and given a value of 1. Each area on the map represents a Census block group and each of the indicators given a value of 1 are added together to get an At-Risk Rank for each area from 0-8. A rank of 0 means there are no At-Risk indicators. A rank of 8 means all At-Risk indicators are present. Areas ranked from 6-8 are considered High Needs areas warranting additional engagement with the local community.

Bondadosa Grocery Delivery

Abarrotes Bondadosa (Bondadosa) is a grocery delivery service with the mBondadosa Grocery Delivery Services Opens in new windowission of increasing fruit and vegetable access for communities across the Denver Metro region. Bondasosa wanted to look at areas in which they could expand their services, particularly into Jefferson County. In knowing the zip codes where their current customers reside, they wanted to investigate whether the areas we have identified as high need, as well as several other demographic characteristics, would help them determine where to look next. This interactive map allows them to view high needs areas, median household income, concentrations of single-parent families, Hispanic and Latino populations and elder populations.

Food Deserts, Food Swamps and High Needs Areas in Jefferson County

Jefferson County Public Health has been identifying High Needs areas in the County for the past five years.  More recently there has been a desire to show the intersection between high needs areas, High Needs Food Access Areas in Jeffco Opens in new windowareas with limited access to grocery stores (food deserts) and areas with an overabundance of fast food options (food swamps). While the USDA provides some data about where food deserts exist the geographic scale makes it difficult to identify neighborhoods where resources may be lacking. This story map describes our process for identifying areas of high needs, food deserts and food swamps; how our methodology differs from the USDA; and how these all intersect.

Food Retail, Food Deserts, Food Swamps (2021)

The Jefferson County Food Policy Council has been using this information to identify Food Retail, Food Deserts, Food Swamps 2021 Map Opens in new windowpotential areas where residents are struggling to access healthy food. Members connect with individuals and organizations to “ground truth” or verify that the data is accurate and identify partners to collaborate with in designing programs and policies to increase food security and ensure access to healthy, nutritious and affordable foods. Stay tuned for updates as the work progresses.

This map depicts the food retails landscape and includes the locations of the following types of food retail:

  • Convenience Stores
  • Restaurants - Fast Casual (fast food, high calorie, low quality, less healthy)
  • Restaurants - Full Service
  • Grocery Stores - Small (may or may not provide fresh meat, fruits and vegetables, dairy, and other unprocessed healthy food options)
  • Grocery Stores - Full Service
  • Also included in this map is a depiction of the density of fast-casual restaurants representing “food swamps.” Areas with a high density of fast-casual food options and an absence of a full-service grocery store may indicate lack of access to healthy food options, and abnormally high access to unhealthy food options.

Additionally, the map shows 1-mile, 2-mile, 5-mile, 10-mile, and 20-mile service areas around full-service grocery stores. Within urban areas, living within 1-mile of a full-service grocery store is generally considered to provide reasonable access to a grocery store and healthy food options. In rural areas living within 10-miles of a full-service grocery store is generally considered to provide reasonable access to a grocery store and healthy food options. Areas outside the 1-mile urban and 10-mile rural service areas are generally considered to be food deserts. The other service areas are provided for context and to represent thresholds that were previously considered reasonable access (2-miles urban and 20-miles rural). The 5-mile service areas may be used to discuss research indicating that most grocery store customers use grocery stores around 5-miles of where they live, regardless of closer options or options further way that may be more culturally desirable.

GoFarm Opportunity Index, Market Matrix and Snap Matrix

GoFarm is a nonprofit organization with a mission to increase the supply of and access to aGoFarm Food Access Maps for Jefferson County Opens in new windowffordable, healthy and local food in Colorado. In 2017, GoFarm worked with students at the Colorado School of Mines to develop a Market Matrix and SNAP Matrix to help identify potential locations for Community Support Agriculture (CSA) delivery. In 2018, Jefferson County Public Health helped update those matrices and developed an additional Opportunity Index that incorporated aspects of both with some additional factors to help identify areas throughout Jefferson County that could benefit from local food sources, such as CSAs.

Hunger Free Golden's Community Needs Assessment gis map

Jefferson County Public Health and Five Points Geoplanning provided GIS and mapping support for the Golden Community Food Assessment, working with Sophie Oppenheimer, the City of Golden, and Hunger Free Golden. Demographic and location data was collected and mapped to visualize the following in and around Golden: at-risk (high-needs) areas, concentrations of SNAP (also known as food stamps) recipients, poverty, median household income, unemployment, local free/reduced price food options, conventional food retailers, public transportation routes, survey locations and respondent home areas. The purpose of this effort is to better understand the barriers to food access in the Golden community; to identify the resources and opportunities that exist to provide affordable and accessible healthy food to the Golden community; and to identify potential solutions for reducing hunger and food insecurity.
