The 2026 Census: what changes and when it reaches .id tools 

New topics, changed questions and the phased release timeline from 2027

 The 2026 Census was held on 11 August 2026. It adds new topics, changes some existing questions and will be released in stages from 2027, so your .id tools will update in stages too. This article covers what changes from 2021 and when to expect the data, so you can plan reporting and strategy work around it. 

What's new and what changes

  • Sexual orientation and gender are two new topics, asked of people aged 16 and over. These questions were not asked in 2021 or earlier Censuses. Informed Decisions will put these new topics on the community profile, subject to ABS confirmation on data quality and available geographies.
  • The sex question has been reframed as “Sex recorded at birth” - it is an existing question with its third response option enhanced. Most likely Male and Female will be the only outputs, the same as currently. Many topics break down by Male and Female and this is expected to continue.
  • Ancestry expands to up to four responses per person, from two at the 2021 Census. Ancestry is already a multi-response topic, so totals already double-count people who give more than one response. With more responses allowed, some categories may record higher counts in 2026 simply because people have more boxes, so take care comparing 2021 and 2026 ancestry figures. The size of this effect is not yet known, but in 2021, about 70% of people nominated only one Ancestry, so the magnitude will not be a doubling of total responses.

When the data are released

The ABS will release 2026 Census data in three phases, and the exact dates are not yet confirmed:

  • a first release around June 2027, covering most topics, including age, households, housing, birthplace, language, religion and education (approximately 75% of the Census topics).
  • a second release around October 2027, covering employment, qualifications, industry, occupation and journey to work.
  • a third release from early 2028, covering distance to work, homelessness counts and the SEIFA indexes.

Treat any specific first-release day you see circulating as unconfirmed. The only date the ABS has given is June 2027, and we will update this article as the ABS firms up the plan. ABS are likely to have a firm release date by around March/April 2027 and we will update our timings then.

When it reaches .id tools

Census data is added to .id tools as soon as possible after each ABS release, so expect 2026 data to start appearing from mid-2027 and to arrive in stages that follow the ABS phases. Because the releases are phased, some topics on your site will show 2026 data while others still show 2021 data, until the later releases land. We expect to update topic-by-topic, with the most widely used topics such as age structure and household type online first, but all within a few weeks after each release.

Frequently asked questions

Q: Will my custom areas survive the 2026 Census?

A: Yes. Custom areas continue once established, so you don't need to re-request them for the new Census. New Census is a good time to adjust your geographies if you need to, so speak to ID if you would like to alter these. Particularly in growth areas where new suburbs may be large enough to profile for the first time. Standard areas such as SA2s will be automatically updated where the ABS has changed them.

Q: When do I need to tell .id about changes to our areas or Communities of Interest?

A: By mid-2027, before the first release arrives, but the earlier the better. If we can implement these changes based on 2021 data and earlier there will be no delay once the 2026 data are released. Your Client Lead is the right contact, or support@id.com.au if you are not sure who that is.

Q: Can .id tell me how to answer a Census question?

A: No. We are not the ABS and don't advise on completing Census forms. The ABS Census hotline is the right place for questions about the form itself.

Q: Will my historical figures change after the Census?

A: Some will. The ABS revises Estimated Resident Population for the previous five years after each Census, and small-area figures that have drifted between Censuses are reconciled once the new Census data is in. Revised Estimated Resident Population - which is not Census data but is based on it - is expected to be released by late July 2027. So there will be a period of close to a month when there is a mismatch between the Census counts of population and the older ERP showing for 2026.

Historical Census data itself doesn’t change, but if you have requested any changes to geographic areas these past years will be adjusted as well to match the new boundaries.
