A complete list of data items included on the ACLD-SSRI file is provided in an Excel spreadsheet that can be accessed from the Downloads tab.

All data items are created at the person level. This includes data items relating to the family and household of the person selected in the sample. For ease of use, these data items have been divided into Person, Dwelling, Household, Family, Spouse Related, and Male and Female parent related groupings.

Users intending to subscribe to the TableBuilder product or use the microdata product in the ABS Data Laboratory should ensure the data they require, and the level of detail required, are available and applicable for the intended use.

The ACLD has been updated since its initial release to add several new data items along with improved derivations for select data items. For the 12 February 2016 update certain data items were more finely disaggregated to expand analytical possibilities. For example, religious affiliation was expanded to the three digit level and year of arrival in Australia in single years. In addition to new Census variables, such as Socio-Economic Indexes of Areas (SEIFA) and dwelling location, three new data items were added from the Department of Social Services' (DSS) Settlement Database that have been previously made available on the Australian Census Migrants Integrated Dataset (ACMID) TableBuilder file. To further enhance the file, a new weight replaced the previous weight to better account for net overseas migration between 2006 and 2011.

The Social Security and Related Information (SSRI) data provided by DSS was added to the file in August 2017, creating the ACLD-SSRI, and includes demographic information (such as Age, Sex, Country of Birth, Partner Status, Marital Status, and Indigenous Indicator), location information and Benefit flags for both the individual and partners, where available. Where data was available, details of an individual’s current partner as of the SSRI extract period was included. This includes the details of any benefits the partner was receiving as well as location and demographic details of the partner. Note that demographic, location and partner information from the SSRI dataset may be different to that reported in the linked Census record.

Benefits have been split into current and suspended flags for each of the benefits as an individual may be claiming multiple benefits. An individual is considered suspended where they are temporarily ineligible for benefits due to not meeting one of the income, assets, or activity tests or suspended pending provision of additional documents. Numeric derived fields for the number of benefits an individual is receiving have also been included. Supplementary benefits, such as Rent Assistance, have not been included in this data. Monetary values related to benefit payments have not been included in the dataset.

Due to small numbers of people on particular payments, some benefits have been grouped.


Overseas visitors were excluded from the 2006 ACLD sample. The ACLD and ACLD-SSRI, however, do include visitors from within Australia in 2006 and/or 2011. These are people who were enumerated away from their usual residence on Census Night. Family information cannot be derived for these persons and as such all family, spouse, and male and female parent related data items are not applicable for visitors.

All dwelling related data items, however, have been made applicable to visitors. This information relates to their dwelling of enumeration on Census Night, not usual residence.

Most household data items are not applicable to visitors, however for four data items, visitors have been included in order to align to standard Census derivations of that data item. These comprise:

    • Total Household Income as stated (weekly) of household in which person was enumerated.
    • Total Household Income (weekly) of household in which person was enumerated.
    • Household Income Derivation Indicator of household in which person was enumerated.
    • Household Composition of household in which person was enumerated.

Any applicable household information for a visitor relates to their place of enumeration, not usual residence.

Where a data item is also applicable to visitors, the usual address indicator data item for the relevant Census year can be used to restrict the table to usual residents only.

The cell comments available in the data item list provide precise information on who is, and is not, applicable for each data item.


The Census household form provides the opportunity to list up to three persons who were temporarily absent from the dwelling on Census Night. A limited amount of information is collected for these persons and it is used to better derive the family and household characteristics of the dwelling. In deriving family and household related data items for the ACLD and ACLD-SSRI, information on persons temporarily absent was included where relevant and available. Details are provided in cell comments in the data items list.


Most data items in the ACLD-SSRI include a 'not applicable' category. The definition of the 'not applicable' category, where relevant, can be found in the Census Dictionary Glossary and A guide to Australian government payments.


'Not stated' categories occur when no response has been provided for a data item. All Census data items contain 'not stated' categories except for age, sex, marital status and usual address, as this information is imputed for these items.

Other Census products commonly use the symbol '&' to denote a code value of 'not stated'. In the ACLD-SSRI, the symbol 'X' or '97' has been used. The codes are listed in the data items list.
