^aEmpirical percentiles were calculated separately for the density of parks, playgrounds, and sports facilities for all schools in NYC. These percentiles were summed, and a new composite percentile was created, representing the overall relative school rank. Tertiles were created based on the distribution of school composite percentiles

^bParticipation in the National School Lunch Program acts as a proxy for household poverty. Students are considered “high poverty” if they are eligible for reduced-price/free meals, meaning their household income is within federally defined poverty limits [34]. Students are considered “low poverty” if they are not known to be eligible
