^aCalculated as relative ratios to quantify the difference in the mean count of fast food restaurants in 2010 compared with 2000 for each neighborhood income tertile within each majority racial/ethnic school subgroup.

^bAvailability was defined as the number of chain and non-chain fast food restaurants within 0.75 mile service area of school.

^cMedian annual household income, classified into tertiles (based on U.S. Census 2000 data).^36–37

^d>50% of the student body in each racial/ethnic classification (based on data from the California Department of Education, 2010).³⁴

^eUrban or non-urban (rural, suburban, second city) households in the census tract (based on data from Nielsen PRIZM urbanization measures, 2013).³⁸

^fSample sizes for non-urban areas for these groups were insufficient to generate stable estimates, thus estimates were excluded or not available.
