  1. NEWS-Y Neighborhood Walkability Scale – Youth, GIS Geographic Information Systems, Th. theoretical. N for some variables is reduced due to missing data. Missing values: Residential density (0.2%), Land use mix – diversity (0%), Land use mix - access (0%), Street connectivity (1.7%), Walking facilities (1.1%), Aesthetics (0.6%), Pedestrian/automobile traffic safety (1.5%), Crime (1.7%), Parking difficult in local shopping areas (0.4%), No major barriers (0%), Hilly streets (0%), Composite subjective index of activity-friendliness (2.1%), Composite subjective index of non-sedentariness (3.4%), Composite objective index of activity-friendliness – 2 km buffer (0%). 0.6% of missing data on Net residential density, Street intersection density, Cul-de-sac density and Number of parks – 500 m and 1 km buffers. No missing data on the remaining GIS variables. Composite objective indices of non-sedentariness not computed as no objective environmental correlates of sedentary time were found
