Note: n = sample, % = proportion. There were 400 students interviewed from 20 high schools (so 20 students per school). Out of 400 youth samples, 382 students were 11–17 years old, 14 students were 18 years old, and 4 students were 19 or 21 years old. There were 492 adults interviewed near those 20 high schools (24–25 adults per school). For neighborhood, poorer/richer areas are with higher/lower subdistrict-level poverty rates. The measures of density and proximity were the same for youth/students and adult samples. Density was measured by the total number of adverts within 400 m of each school. For density, basic descriptive = mean 9.75, standard deviation 7.97, and range 0–24.
