Microdata and TableBuilder: Permanent migrants in Australia

This product provides information about the release of microdata from the Australian Census and Migrants Integrated Dataset (ACMID) in TableBuilder and DataLab.

Microdata are the most detailed information available from a Census or administrative data collection process and are generally the responses to confidentialised/de-identified individual questions on questionnaires or forms. They also include derived data from answers to two or more questions.

The Australian Census and Migrants Integrated Dataset (ACMID) contains data on people who were granted a permanent Skilled, Family, Humanitarian or Other Permanent visa and arrived in Australia between 1 January 2000 and Census night. These datasets link data from the Census of Population and Housing (Census) with the Department of Home Affairs (Home Affairs) Settlement Database.

The Census is conducted every five years to measure the number of people and dwellings in Australia on Census night. The Census also provides information on the key characteristics of people and dwellings for small geographic areas and small population groups.

You can use this data in:

• TableBuilder - online tool for creating tables and graphs.
• DataLab - analyse detailed microdata.

Compare data services to see what's right for you. Information on how to apply for access can be found in TableBuilder and DataLab.

Further information about these products, and other information to assist users in understanding and accessing microdata in general, is available from the Microdata and TableBuilder Entry Page.

Customised tables are available on a fee-for-service basis. Enquiries should be submitted via an Information consultancy form. 

The ABS Privacy Policy outlines how the ABS handles any personal information that you provide to us.
 

The ACMID contains several data items that allow people to select more than one answer. As respondents can select multiple responses, care must be taken interpreting counts and totals.

• The Ancestry variable allows respondents to report up to two ancestries on their Census form. Refer to Understanding and using Ancestry data for information on how to use this data item.
• From 2021 the Long-term health condition variable allows people to report multiple long-term health conditions. Refer to the 2021 Census Dictionary for information on how to use this data item.

Most data items included in the microdata include a 'Not applicable' category. The classification value of the 'Not applicable' category, where relevant, are shown in the data item lists in the Data downloads section.

Data items relating to a person’s visa characteristics include:

• the visa class of a person's entry into Australia
• their country of citizenship
• whether the visa was granted onshore or offshore (available in 2011 and 2016 only)
• whether the person was the primary or secondary applicant for the visa.

In the 2021 ACMID visa transition data items were added. These data items relate to the visa history data from the Department of Home Affairs for each linked person record.

In DataLab, a separate file is available to facilitate analysis of people's visa grant history and visa transitions.

Information or data from the Australian Bureau of Statistics must be acknowledged responsibly whenever it is used. Citing, or referencing is important for several reasons, including acknowledging that one has used the ideas, words or data of others. Accurately citing sources used also allows others to find and use the original information.

The data in TableBuilder is subject to a confidentiality process before release. This confidentiality process is undertaken to avoid releasing information that may allow the identification of particular individuals, families, households, dwellings or businesses.

Processes used in TableBuilder to confidentialise records include the following:

• perturbation of data
• table suppression.

See confidentiality in the TableBuilder user guide for more details.

The TableBuilder product is a single-level file that counts persons and has data items as collected at the Census of Population and Housing.

A complete list of data items included on each ACMID product is provided in the Data downloads section. For the 2011 ACMID product, see 2011 ACMID TableBuilder file structure.

Topics include general demographic and geography characteristics, employment, income and unpaid work, education and qualifications, cultural and language diversity, migration characteristics, as well as permanent visa characteristics.

All data items are created at person level. This includes data items relating to the dwelling, family and household of the person linked in the dataset. For ease of use, these data items have been divided into Person, Dwelling, Household, Family and Spouse Related groupings.
 

The DataLab is an analysis solution available for users to run complex statistical analyses.

Controls in the DataLab have been put in place to protect the identification of individuals and organisations. These controls include environmental protections, data de-identification and confidentialisation, access safeguards and output clearance.

Information about accessing and using the DataLab are available via the DataLab information and Using your workspace pages.

Using DataLab responsibly and Responsible use of ABS microdata explain your obligations as a user of ABS microdata products.

The DataLab allows real time access to microdata files through a portal to a secure ABS environment. Using detailed microdata in DataLab allows users to run advanced statistical analyses using recent analytical software.

All unit record data remains in DataLab, and all output from DataLab sessions must be approved by an ABS officer before it is released. Further information is available via Input and output clearance.

For information about the data items available on the detailed microdata files, see the Data Item Lists in Data downloads.

Data produced using the detailed microdata files in the DataLab will not necessarily match published data or data obtained through the TableBuilder product, both of which are perturbed prior to release to ensure confidentiality is maintained. Due to the procedures used for confidentialising the data produced via the DataLab, perturbation is not required.
