  1. GIS Geographic Information Systems, MVPA Moderate to-vigorous physical activity, SED Sedentary time
  2. Note: Higher scores for potential correlates indicate hypothetically greater support for physical activity or sedentary behaviour, except otherwise indicated; 1: Higher score reflects more rules restricting screen-time; 2: Higher score reflects higher perceived crime, see Table S1 for further details regarding scoring
