Percentages represent percentage of census tracts with a characteristic. Chi-squared test used for to test for lack of independence between unhealthy food quartiles and categorical census tract characteristics while ANOVA was used to test for equivalence of means for population aged 40 years of age and older between quartiles of unhealthy food access. Census tract characteristics were acquired from the 2010 Decennial Census.
