Definitions
Unadjusted results: reflect the actual percentage (or mean) for the specified population in each time period. It is important to note that differences in the population structure may explain some of the variations between DHBs.
Data calculation/treatment
All results presented in this data are weighted so that they are representative of the total population of adults 15+.
The dataset includes unadjusted prevalence figures for most indicators, estimated number of people, and 95% confidence intervals.
Indicators are provided by age group, gender, ethnic group (total response ethnicity, ie where people who belong to more than one ethnic group are counted once in each of the ethnic groups they identify with) and neighbourhood deprivation (area-based measure of socioeconomic position or deprivation).
Sample sizes for small regions are not sufficient to produce reliable estimates for single years. However, reliable regional level statistics can be produced by pooling annual data to improve the range and statistical quality of analyses that can be undertaken at that level. Pooling annual NZHS data sets can also improve the statistical precision of estimates for Māori and ethnic minorities (including Pacific and Asian ethnic groups).
Limitations of the data
Values with high error margins are not shown in the chart(s) above.
Exclusions
Not included in the survey were: people living in institutions (such as for long-term hospital care, hospital- and dementia-level care in aged-care facilities, and in prisons), the homeless, short-term visitors and tourists.
