Households were drawn from the Register of Quarters maintained by the Census and Statistics Department by systematic replicated sampling. The percentage of quarters successfully enumerated (including those without children aged 14 and below) was 73.3%. A total of 7393 land-based non-institutionalized children aged 14 and below in Hong Kong were enumerated, excluding those with non-Cantonese speaking parents and those living in area segments in non-built-up area. The sample represented 884 300 children of the target population.
