The sampling was performed to avoid overlap between schools and neighbourhoods. When there was a sampled neighbourhood overlapping with a sampled school, the neighbourhood was excluded and replaced by another neighbourhood through random sampling. Food stores include convenient stores, small markets, and supermarkets (the same below).
