This is the percentage of the population affected (that is, the unadjusted prevalence in the specified population).
Estimated numbers are rounded to the nearest 1,000 people.

Notes:
Adjusted proportion ratios are used to compare the results for different population subgroups. An adjusted ratio above 1 shows that the indicator is more likely, and an adjusted ratio below 1 shows the indicator is less likely, in the group of interest (e.g. Māori) than the reference group (e.g. non-Māori), after adjusting for demographic variables that could influence the association.
Kaupapa Māori consistent data analysis planning was supported by Māori and Pasifika advisors at Health New Zealand. In alignment with Kaupapa Māori research and Te Tiriti ō Waitangi principles, comparisons were made between ethnic groupings in order to identify ethnic inequities.
Equity-based ethnicity is only used for comparisons and is another form of total response. Unlike total response, which compares one ethnic group with everyone else in the sample, equity-based ethnicities compare Māori to non-Māori and non-Pacific. The same comparison group is used for Pacific peoples.

| Pacific Equity | |||
| Pacific vs non-Pacific & non-Māori | 0.99 | ( 0.9 - 1.09 ) | Age, Sex |
| Men: Pacific vs non-Pacific & non-Māori | - | - | Age |
| Women: Pacific vs non-Pacific & non-Māori | 1 | ( 0.91 - 1.09 ) | Age |
| Māori | |||
| Māori vs non-Māori | 1.04 | ( 1 - 1.07 ) | Age, Sex |
| Men: Māori vs non-Māori | 1.04 | ( 0.98 - 1.1 ) | Age |
| Women: Māori vs non-Māori | 1.03 | ( 0.99 - 1.07 ) | Age |

| Neighbourhood deprivation | |||
| Most deprived vs least deprived | 1 | ( 0.95 - 1.05 ) | Age, Sex, Ethnicity |
| Men: Most deprived vs least deprived | 0.99 | ( 0.92 - 1.07 ) | Age, Ethnicity |
| Women: Most deprived vs least deprived | 1 | ( 0.94 - 1.06 ) | Age, Ethnicity |
For example, an adjusted ratio of 1.50 for Māori vs non-Māori means that the indicator is 1.5 times more likely in Māori than non-Māori, after adjusting for differences in demographic variables such as sex and age.
A highlighted value indicates that the adjusted ratio is statistically significant ( p value < .05).
