Infants (<1 year old): 1,000 x (Numerator ÷ Denominator)
Children (0–4 year olds): 100,000 x (Numerator ÷ Denominator)

Calculated separately for each of the two age groups, and for all Australians, Indigenous and non-Indigenous Australians.

Variability bands are to be calculated for single-year rates and aggregate rates by state/territory using the following method for estimating 95% confidence intervals:

Crude rate

Where d=the number of deaths in the relevant age-group.

Presented as:

• number of deaths per 1,000 live births (infant)
• number of deaths per 100,000 population (child).

Rate ratios and rate differences are calculated for comparing Indigenous and non-Indigenous Australians.

• Number of deaths among infants (aged < 1 year).
• Number of deaths among children aged 0–4 years.

• Number of live births; and
• Population aged 0–4 years.

2009-11 — State and territory.

2007-11 — State and territory, by Indigenous status.

2007, 2008, 2009 (resupplied for revision to ABS WA and national Indigenous deaths data), 2010 (supplied for Indigenous status), 2011 — Nationally, by Indigenous status.

Some disaggregations may result in numbers too small for publication. Disaggregation by Indigenous status will be based on data only from jurisdictions for which the quality of Indigenous identification is considered acceptable - NSW, Qld, WA, SA and NT.

Most recent data available for 2013 Council of Australian Governments (COAG) Reform Council (CRC) report:

• 2011 (released Nov 2011)
• 2009-11 (Total population)
• 2007–2011 (Indigenous status).

Because of small numbers of deaths each year data are presented in 3 (total population) or 5-year (Indigenous population) groupings (state and territory only).

Single year data (2011) will be reported for time series analysis (national level only). 

A system error affected the reporting of WA Aboriginal and Torres Strait Islander death registrations for 2007, 2008 and 2009 which affected the WA and national death rates reported for the 2011 and 2012 CRC reprots. These data have been revised for 2013 reporting.

Data by remoteness may be available, pending assessment of data quality.

For further detailed analysis by Indigenous status see the National Indigenous Reform Agreement (NIRA) report.
