None of this is hidden. The ABS published every caveat below on the same website as the headline, in the methodology attached to the release. The point of this piece is that the headline travels and the methodology does not, and on this beat the difference matters: prevalence figures get used to argue about scheme size.
The headline numbers
| Measure | 2022 | 2018 |
|---|---|---|
| People with disability | 5.5 million, 21.4% | 17.7% |
| Profound or severe disability | 7.9% | |
| Aged 0 to 64 with disability | 15.0% | |
| Aged 65 and over with disability | 52.3% | |
| Carers | 3.0 million, 11.9% | 10.8% |
Prevalence is similar for males (21.0%) and females (21.8%)
, and the share of
Australians aged 65 and over rose to 17.1% of Australians were aged 65 years and over (up
from 15.9% in 2018)
. Some of the prevalence rise is that ageing, since disability is
strongly age-related: 15.0 per cent of people under 65 against 52.3 per cent of those over
it. Ageing alone does not obviously carry 3.7 percentage points in four years.
What changed in how the survey was run
The methodology is direct about the comparison. It says
Most data in the 2022 SDAC is considered to be comparable with previous Surveys of
Disability, Ageing and Carers
, and immediately after,
However, comparisons should be made with caution
. Three changes sit behind that
sentence.
The survey went online for the first time.
Respondents to the SDAC household component had the option of completing the questions via
online questionnaire without the presence of an ABS interviewer
, and
This was made available to SDAC respondents for the first time in 2022 and 41.0% of
respondents completed the survey this way
. The ABS notes the consequence plainly:
These respondents were not able to ask clarifying questions of an ABS interviewer as they
would have been able to do in previous SDAC collections
.
The disability confirmation sequence changed.
While there was little change to the questions used to screen household members for
disability the question sequencing and method for confirming disability during an
individual's personal interview has changed
. Crucially, and this is the part that stops
the story being a simple debunk:
The disability status definition and disability types used to identify disability have not
changed
.
The carer questions were redesigned to find more carers.
There has been some change to questions that identify carers during household screening
with the intent of maximising primary carer identification early in the interview
, and
the questions confirming primary carer status
also have sequencing and structural changes
. The carer share rose from 10.8 to 11.9
per cent over the same period.
And one population moved between components.
In the 2022 SDAC disability group homes with less than six residents were included in the
cared-accommodation component. This is a change from the 2018 SDAC where they were included
in the household component
.
What this does and does not mean
Our view, on the ABS's own account: the 21.4 per cent is the best national estimate available and should be used, and it should not be reported as a clean four-year trend against 17.7 without saying that the measuring instrument changed in between. The definition did not move, which rules out the simplest explanation. A mode shift affecting 41 per cent of respondents, a changed confirmation sequence, and carer questions explicitly redesigned to identify more carers are the kind of changes that move self-reported prevalence, and the ABS flagged them rather than burying them.
What we cannot do, and will not pretend to, is decompose the rise. Nothing in the summary release or the methodology quantifies how much of the 3.7 points is ageing, how much is instrument, and how much is a real change in the population. That decomposition would need the ABS to publish it or a researcher to model it, and neither is on the page.
The other problem: this is a 2022 picture
The release page states a reference period of 2022, a release date of 4 July 2024, and a next release of Unknown. It is the tenth survey in a series that runs 1981, 1988, 1993, 1998, 2003, 2009, 2012, 2015, 2018 and 2022. The gaps have been three to four years, and the publication lag on this edition was two years from reference period to release.
So policy arguments made today about how many Australians have disability are being made on a survey taken four years ago, published two years ago, with no announced successor. That is a fact about the evidence base rather than a criticism of the statisticians, and it is worth stating whenever the 21.4 per cent is quoted at a hearing.
How we did this
Read from the ABS Survey of Disability, Ageing and Carers summary of findings for 2022 and its attached methodology page, both read on 29 August 2026. Every figure and every quoted phrase is the ABS's own; we have calculated nothing. The 2018 comparators are the ABS's, taken from the same summary page where it states the change itself. We have not decomposed the rise, estimated any component of it, or attributed it to any single cause, because the sources do not support that and we say so in the article. We have not contacted the ABS. No individual or organisation is named beyond the ABS as publisher, and the opinion offered is labelled as ours and rests on the ABS material quoted above it.
