OTHER STANDARD RELEASES
Sets of 28 tables, selected from tables contained in National Health Survey: Summary of Results, Australia 2001 (cat. no. 4364.0), but compiled for individual states and the ACT are available in EXCEL spreadsheet format from this web site.
Also available are 23 tables, based on published tables, compiled by broad categories from the ASGC Remoteness classification. A similar set of tables but compiled to categories from the Accessibility and Remoteness Index of Australia (ARIA) is available through ABS@ Health.
A set of detailed tables presenting additional Indigenous results from the 2001 NHS(I) will be progressively made available via this web site.
ACCESS TO MICRODATA
In considering the release of microdata, the ABS is governed by its legislative obligation not to release information in a manner that is likely to enable the identification of a particular person or organisation. Under this obligation, the ABS is concerned to protect against two main types of risk; spontaneous recognition and matching against other data sources. In order to ensure the confidentiality of respondents the ABS usually removes some items from the microdata it makes available, and reduces the level of detail shown for some other items. However in this process the ABS is conscious of the need to find an appropriate balance between ensuring confidentiality while maximising the usefulness of the data set to users of the data.
In the past, ABS has released confidentialised data files on floppy disc or CD ROM. To better meet needs for access to microdata the ABS has introduced new arrangements whereby users of the data are granted monitored access to a confidentialised data file; access may be remote or on-site at ABS offices. This arrangement enables greater security around access to, and use of the file, and hence enables more detailed information to be made available than can be released on CD ROM.
For the 2001 NHS, two confidentialised unit record files will be made available from late March 2003:
These files contain all 26,863 records from the survey, but some data items have been removed, and the level of detail for some others has been reduced to protect the confidentiality of survey respondents. In addition to the inclusion of State and Territory identifiers, the RADL file contains more detailed information than the CD ROM file across a selection of demographic and health data items. For further details, including a full list of the data items they contain, see Information Paper: National Health Survey, 2001: Confidentialised Unit Record File, which is available from the ABS web site. The price of the files is $8,000.
A more detailed 2001 NHS(G) file is under consideration for release through RADL mid-2003. Also under consideration for release is a RADL file containing confidentialised unit record information from the 2001 NHS(I). Further information concerning these releases will be posted on the ABS web site at the appropriate times.
Release of all confidentialised unit record information is subject to the approval of the Australian Statistician, and is contingent upon purchasers of the files, and all persons using the files thereafter, signing undertakings to abide by the legislative restrictions on use and such other conditions of sale as may be determined by the Australian Statistician. These include use of the data for statistical purposes only, not attempting to identify particular persons or organisations and not attempting to match the information with any other unit level list of persons or organisations. Full details of the conditions of sale and use, together with application and undertaking forms, are contained in the Information Paper: National Health Survey, 2001: Confidentialised Unit Record File.
In addition to products outlined above, a range of special data services are available on request, on a fee for service basis. Subject to sampling and confidentiality constraints, tables can be compiled to individual specifications, and other data and analytical services are available. For people wishing to request special tables, a list of all output data items available from the survey can be accessed through this web site. For further information, contact the Health Section of the ABS in Canberra.
For clients interested in further information or special data services available from the 2001 NHS Indigenous data, please contact Client Services in the ABS Darwin Office on 1800 633 216. Clients should be aware that, given the relatively small sample size of the 2001 NHS "total Indigenous sample", the geographic breakdown of the Indigenous information is limited. Data are not available for States or Territories.
