#### Description

Percentage of Aboriginal and Torres Strait Islander adults (18+) reporting high level psychological distress by age group: 18–24, 25–34, 35–44, 45–54, 55 and over

#### Data source

Australian Bureau of Statistics (ABS) National Aboriginal and Torres Strait Islander Health Survey, 2018–19 (see ABS 2019a, 2019b)

#### Region types reported

Australian Statistical Geography Standard (ASGS) 2016 Main Structure regions: State/territory, Australia

ASGS 2016 Indigenous structure regions: Indigenous Regions (IREGs)

#### Suppression rules

Data have been suppressed if the denominator for the percentage was less than 100, due to concerns about the reliability of percentages based on small denominators. Data have been flagged as use with caution if the margin of error was between 10 and 15 percentage points.

Data have been suppressed if the margin of error was above 15 percentage points, or where a margin of error could not be reliably calculated (see ‘Notes’).

#### Notes

Data are based on AIHW analysis of ABS microdata (ABS 2019a).

Denominator for the percentages includes Indigenous Australians aged 18 and over.

Age-specific percentages of Indigenous Australians aged 18 and over with high levels of psychological distress are reported in selected regions: state/territory, remoteness (5 areas), and national level.

Data have been randomly adjusted by the ABS to protect confidentiality. No reliance should be placed on small numbers.

A margin of error (MOE) was calculated for each percentage at the 95% confidence level. At the 95% confidence level, the MOE indicates that the probability that the estimated percentage would differ by less than the specified margin of error from the true population value (the percentage obtained if data about the whole population were available) is about 95%. Percentages with a margin of error greater than 10 percentage points have been flagged as interpret with caution and/or suppressed (see ‘Suppression rules’). In some cases, the relative standard error of the percentage, used to derive the MOE, was suppressed in the ABS source data due to reliability and/or confidentiality concerns (ABS 2019c). In these cases, the ABS considers the associated percentages too unreliable for general use. Accordingly, when the MOE could not be calculated, the percentage in the Regional overview has been suppressed.
