Frequently Asked Questions


Frequently Asked Questions


I've been chosen to be in the Post Census Review – what is this?
This is an important national survey that is conducted after every Census. This survey helps us determine how many people were counted more than once, or were missed in the Census, and is used to improve estimates of Australia’s population. It is vital that we get these numbers right to improve planning for Australia’s future, including where schools, hospitals and other services are needed.

How is the information from this survey used and why is it important?
Your participation in this survey is an opportunity to make a real difference. Results are used by governments, researchers and community groups to better understand the number of people living in all areas of Australia.

Decisions like where schools, hospitals and other services are needed, setting electoral boundaries and how public funds are spent can be made by analysing data from this survey. The information you provide will help to shape policies and services which improve the lives of all Australians.

Why was my household selected?
You may recall that you were selected to participate in the 2020 Census Test. The Post Census Review immediately follows each Census and it is important that we also test this survey. You need to participate in this survey whether or not you completed the test of the Census.
Where the Census aims to collect information from every person in Australia on Census night, this survey uses a scientific sampling process to collect information from a small part of the population to build a picture of Australia as a whole. All households have a chance of being selected for this survey.

Once a household has been selected, another household cannot be substituted in its place, as changing the random selection could mean some parts of the community are under or over represented.

It is important that all selected households complete the survey in order to make sure the results represent the whole community. This means that decisions made about services provided by government, local councils and community groups are made using the most accurate information.

How do I complete the survey?
The survey is conducted over the phone and usually takes less than 10 minutes. We ask a few quick questions to check that we have the correct Census information and that the numbers are accurate.

If you are ready to complete the survey on the spot, simply contact our team on 1800 143 967, Monday to Friday 9am to 8pm AEDT and Saturday to Sunday 11am to 5pm AEDT.

Alternatively you can register online to arrange a call back from one of our team to complete the survey at a time that is convenient for you.

If we don't hear anything from you before the due date (as shown on the letter you received), one of our interviewers will contact you to set up an appointment to complete the survey with you.

Who in my household will be required to participate?
This survey collects general information about each person in the household, including visitors. Anyone in your household, aged 15 years or over, can complete the survey on behalf of all the household members and visitors. This should be someone who is best placed to answer these kinds of questions for everyone in the household.

What kinds of questions will you ask?
This survey collects general information about your household and includes questions about age, sex and relationships within the household. The survey also asks:

  • whether each person in the household was included on a Census form, and if so, at what address
  • whether each person in the household could have been included on a Census form at other addresses
  • where each person in the household was staying on Census night.

How do I know the person contacting me is from the ABS?
If your household has been selected to participate in this survey, you will have received a letter and flyer informing you of your selection.

For any personal visits, our staff will always identify themselves, show you their official ABS photo identification and clearly explain the information they are seeking and how this will be used.

If you have left your contact details, you may receive calls from numbers that you are not familiar with, including mobile phone or “unknown” numbers. This is because many of our Interviewers are teleworkers and use ABS authorised mobile phones and office phones, connected to our highly secure networks, to conduct interviews over the phone.

Remember -The ABS will NEVER ask you to provide or confirm your bank details.

If you are concerned, call us on 1800 143 967 and we will confirm your selection in the survey and the identity of the Interviewer who is contacting you.

What happens if no one in my household speaks English?
Where possible, we can arrange for an ABS interviewer who is fluent in the language of the householder to conduct the survey over the phone. You can call us on 1800 143 967 to arrange an Interviewer. If there is someone in the household who can translate, and the respondent agrees, they can help the interviewer. Anyone aged 15 years or over can complete the survey on behalf of all household members and visitors.

Will I be paid for my time?
No. There is no provision within the Census and Statistics Act 1905 to reimburse people for the cost of providing statistical information. In line with other national statistical organisations throughout the world, individuals, businesses and other organisations are asked to supply information for statistical purposes without compensation. It is only with the support of people like you that we can continue to produce the statistics that inform Australia's important decisions.

How will you keep my information safe, secure, and confidential?
We take the security of the information you provide to us very seriously. Your information remains strictly confidential to the ABS and is not shared with other agencies. We use the information you provide to calculate statistics, which are released in ways that do not allow for the identification of individuals or households. Like the Census test, data collected from the PCR test will not be released.

All ABS employees have signed a legally enforceable Undertaking of Fidelity and Security in which they agree to keep any information, including personal information which they may deal with in the course of their work, private and confidential. This agreement applies to ABS employees for the rest of their lives, even if they leave the ABS. The penalty for breaching this is two years jail, a $26,640 fine, or both.

We comply with the Australian Privacy Principles. If you believe we have breached these principles, please see the information on how to lodge a complaint about privacy matters, contained within our privacy policy.

Will the information I provide be combined with other data?
The information you provide will be combined with the information from other respondents to produce vital statistics about Australian households.

The purpose of the Post Census Review is to match a respondent’s information to their Census information to understand how many people were missed, or counted twice in the Census. Doing this provides a check on the quality of the Census and improves our population data. It is vital that we get population numbers right to improve planning for Australia’s future, including where schools, hospitals and other services are needed.

How can I provide feedback about my experience in the Post Census Review?
If you have participated in this survey, or any of our other surveys, we want to hear about your experience. We value your feedback and will use it to improve how we work with our survey participants.

You can use our feedback form to provide us with feedback. For this survey, please select the option "Participation in an ABS Household Survey".
