FILE STRUCTURE

The ACLD-SSRI product in both TableBuilder and DataLab is a single-level file that counts persons and has data items for 2006 and 2011.

In TableBuilder, data items have first been separated by year of collection. Each data item for the person in 2006 has a corresponding item in 2011. In addition, data items that provide longitudinal information derived from both years, such as the consistency in reporting of certain data items between 2006 and 2011, is in a folder labelled 'Longitudinal' (see also Using the ACLD-SSRI in TableBuilder). In addition to Census variables, there are three data items relating to migrants that have been made available via the Settlement Database (SDB) from the Department of Social Services and 44 data items relating to social security payments that have been made available via the Social Security and Related Information (SSRI) dataset from the Department of Social Services. These data items are only available for 2011.

For each year, data items are further divided into the following groups:

Geography - geographic classifications on both a usual residence and place of enumeration basis.
Person - person-level characteristics, covering demographic, culture and language, education, employment and unpaid work topics.
Dwelling Related - derived from the characteristics of the dwelling in which the person was enumerated - e.g. type of dwelling.
Household Related - derived from the characteristics of the household in which the person lives, provided the person was counted at home on Census Night - e.g. total weekly household income.
Family Related - derived from the characteristics of the family in which the person lives, provided the person was counted at home on Census Night - e.g. age of youngest child in family.
Male Parent - derived from information about the person's male parent, provided the parent was counted in the same family on Census Night - e.g. labour force status of male parent.
Female Parent - derived from information about the person's female parent, provided the parent was counted in the same family on Census Night - e.g. labour force status of female parent.
Spouse/Partner - derived from information about the person's spouse/partner, provided the spouse/partner was counted in the same family on Census Night - e.g. highest educational attainment of spouse/partner.

Where available, migrants data were provided for the spouse/partner, male parent and/or female parent, and SSRI data for the spouse/partner.


UNLINKED RECORDS

The ACLD-SSRI file contains all records from the ACLD 2006 Census sample, both those that were linked to a 2011 Census record and those that were not. Records that were linked have information for 2006 and 2011. Records that were not linked have information for 2006 only. This may assist in exploring the differences in linkage rate between the 2006 Census sample and 2011 Census records for different sub-groups.

SDB and SSRI records which were not linked to ACLD records are not included in the linked dataset.

Excluding Unlinked Records in TableBuilder


When using the weighted summation option in TableBuilder, no results will be returned for unlinked records in 2011 as weights were not applied to these records. Results will be returned if analysis is performed on unweighted data only. If desired, this category can be excluded from tables by ensuring that the 'unlinked record' category is deselected before each data item is added to the table. Such a table would produce a sample count corresponding to the equivalent table run with weights. Refer to the TableBuilder, User Guide (cat. no. 1406.0.55.005) for more information on how to select data items for tables.




If the 'unlinked record' category is present on a data item that has already been added to a table, it can be removed by selecting this category within the relevant data item and then pressing the 'Remove from Table' button.



Note that removing any category, such as the 'unlinked record' category, from a table where data has already been generated will clear all data, meaning the table will need to be rerun.

Also note that the 'unlinked record' flag only refers to not achieving a link from a 2006 Census record to a 2011 Census record, without reference to the SDB or SSRI linking processes.
