Geographic variation
Aboriginal children were less likely to live in major cities than non-Aboriginal children (41.4% vs. 72.3%, p<0.001) (Table 1, Fig. 1A). No Aboriginal children included in the entire study cohort lived in the least disadvantaged areas compared to 19.5% of non-Aboriginal children (p=0.0028) (Table 1). There was a higher proportion of Aboriginal children from middle SES compared to non-Aboriginal children (75.9% vs. 60.1%, p=0.028). Rates of residence within the most disadvantaged areas were similar between the groups (20.7% vs. 19.7%) (Table 1).
