Questions We Asked ...
➢ Do some neighborhoods have overabundance of
undesirable food sources relative to the presence of
desirable sources in Cleveland?
➢ Are neighborhoods in food swamps correlated with
demographic characteristics such as race and income?
➢ What can we learn about food access, food justice and
related policies from this analysis?

Methods We Used ...
➢ Create a database of food sources
➢ Create a database of homes
➢ Organize demographic data for homes
➢ Spatial analysis using GIS to measure proximity and access
○ Network analysis was used instead of linear distances
➢ Compare results across block groups
➢ Explore policy implications of findings

Conclusions ...
➢ Low-income and low-access characteristics are
correlated with obesity, diabetes, some cancers, mental
illness, heart disease, high cholesterol, and mortality
rates (CDC).
➢ Policy efforts need to be spatially calibrated to improve
access to healthy food and advance food justice.
