Data quality | |
Data quality statement summary: | 1. The quality of data about Indigeneity varies substantially between jurisdictions and data sources. Caution should be exercised when interpreting these data. It is recommended that these data be viewed in close conjunction with information about the data quality.

Institutional environment: | The AIHW is an Australian Government statutory authority accountable to Parliament and operates under the provisions of the Australian Institute of Health and Welfare Act 1987. The AIHW provides expert analysis of data on health, housing and community services. More information about the AIHW is available on the AIHW website.

Timeliness: | CSTDA NMDS 2007–08 and 2008–09
|
Accessibility: | The AIHW provides a variety of products that draw upon the CSTDA NMDS. Published products available on the AIHW website are:

Interpretability: | Information to assist in interpretation of the performance indicator is contained in the NDA performance indicator glossary, which accompanies these Data Quality Statements. Supporting information on the quality and use of the CSTDA NMDS are published annually in ‘Disability support services’ available in hard copy or on the AIHW website (<www.aihw.gov.au>). |
Relevance: | Data from several different sources, each referencing different time periods, are used to produce performance indicator (f). Data used are from the CSTDA NMDS 2007–08 and 2008–2009, SDAC 2003, Indigenous Projected Population June 2007 and June 2008, and Census 2006. This may reduce the overall quality of the estimates. Some particular issues are listed in the Relevance section of the Data Quality Statement for performance indicator (c). Additionally,
To facilitate comparability of data, specialist psychiatric disability services in Victoria, Queensland and Western Australia are excluded from the NDA performance indicators. That is, the data excludes those who only receive specialist psychiatric disability services, but does not exclude those people with a psychiatric condition who receive other specialist disability services. In addition, the predominant service models vary across jurisdictions, and this may affect comparability of data. For example, differences across the states and territories in the predominant model of accommodation support lead to differences in the number of people accessing those services. Caution is recommended in the use or interpretation of performance at the service type level. There is a risk when service type level data is interpreted in isolation as various service types are complementary and the emphasis on different services reflects jurisdictional policy directions. For more information, see Disability support services 2007–08 and Disability support services 2008–09 (forthcoming). |
Accuracy: | A potential source of error in the CSTDA NMDS is people for whom Indigenous status is not stated or not collected. For 2008–09, the not stated/not collected rate varied across jurisdictions from a low rate of 0.2% for Australian Government agencies, to a high rate of 12.6% for Victorian agencies; the overall rate being 4.6%. For 2007–08, the not stated/not collected rate varied across jurisdictions from a low rate of 0.1% for Australian Government agencies, to a high rate of 12.1% for Victorian agencies; the overall rate being 4.7%. See the accompanying appendix for further details. Not stated or not collected Indigenous status may introduce bias into the results affecting both the accuracy of estimates and the comparability of estimates across jurisdictions. In addition, a coding audit of the Indigenous status data item has not been undertaken, thus the accuracy of the rate of Indigenous identification in the NMDS is not known. For general issues relating to the CSTDA NMDS, refer to the CSTDA NMDS Data Quality Statement.
Estimates of the Indigenous net undercount for all jurisdictions are included below.

Coherence: | For general issues relating to the CSTDA NMDS, refer to the CSTDA NMDS Data Quality Statement.
A combination of data quality issues, as discussed in this and previous sections, has led to this impossible figure.
They may instead have a mild/moderate core activity limitation or limitations in other activities—for example, with working or education. This mismatch is more evident in certain types of services, such as open employment services, which are not necessarily tailored towards people with a severe or profound core activity limitation.
