SES = socioeconomic status, N = number, SE = Standard Error; IQR = Inter-Quartile Range; 1 Several schools are combined, therefore the number of school grades will be greater than the total number of schools; 2 Minimum nutrition foods served ‘never’; 3 Food availability is % of schools that serve foods more than ‘never’; composite measures are for serving any of the quick or slow foods and include missing data in totals.
