USING THE BASIC CONFIDENTIALISED UNIT RECORD FILE (CURF)
ABOUT THE DATA ITEMS
The full classification structures for all Basic CURF data items can be found in the Census Dictionary, 2016 (cat. no. 2901.0).
Many of the classifications in the Basic CURF have been collapsed and the full listings of the Basic CURF classifications are detailed in the Data items lists in the Downloads tab.
Dwelling, Family and Person IDs
|Each record level are given an identifier:
- Dwelling (Household) - ABSHID
- Family - ABSFID
- Person - ABSPID
To enable users to link records, the following Identifiers are available across levels:
- ABSFID and the related ABSHID on each Family record
- ABSPID and the related ABSFID and ABSHID on each Person record.
Dwelling Indicator for Persons
The DWIP (Dwelling Indicator for Persons) variable was introduced in 2006 as a way of enabling users of the microdata files to more easily distinguish between those people enumerated in private dwellings and those enumerated in non-private dwellings (without the need to link to the household file). This variable was applied in 2011 and is included in 2016 as well.
The DWIP variable applies to all persons enumerated in an occupied private dwelling or non-private dwelling. Categories are:
1 Enumerated in an occupied private dwelling
2 Enumerated in a non-private dwelling.
As migratory, off-shore and shipping areas were not included in the sample, there is no `Not applicable' category for this variable.
The Basic CURF contains information on the geographic area of selected dwellings. For 2016, geographic areas in the Basic CURF are based on the Australian Statistical Geography Standard (ASGS).
To ensure that the information on the file is not likely to enable identification of a person or household, all areas will be defined using a minimum population size of 250,000 persons (except for the Northern Territory which has a total population of 228,833 persons) from the full Census. Records will be randomly ordered within a region to further reduce the likelihood of individual identification.
All regions can be aggregated to the state level as in the 2011 files.
Geographic regions will be formed from Statistical Area Level 4 and form the basis of the following data items:
- AREAENUM (Area of enumeration);
- REGUCP (Region of usual residence on Census night);
- REGU1P (Region of usual residence 1 year ago); and
- REGU5P (Region of usual residence 5 years ago) data items.
A full list of regions is included in the Data Item List.
