About these numbers
The NZ Health Survey interviews about 13,000 adults and the parents of about 4,000 children each year. Figures are the share of adults (15+) or children (0–14), with 95% confidence intervals.
Area deprivation uses the NZ Deprivation Index: quintile 1 is the least deprived fifth of neighbourhoods, quintile 5 the most deprived.
Changes over time can reflect changes in the survey as well as in health. The 2019/20 and 2020/21 surveys were disrupted by COVID-19.
