^*Represents results with statistically significant increases or decreases at the p < 0.05 level over the period 1998–2006.

^(a) Data exclude 90 registered infant deaths where Indigenous status was not stated over the period 1998–2006 in Queensland, Western Australia, South Australia and the Northern Territory combined.

^(b) Average annual change in rates, rate ratios and rate differences determined using linear regression analysis.

^(c) Per cent change between 1998 and 2006 based on the average annual change over the period.

^(d) Mortality rate for Indigenous infants divided by the mortality rate for non-Indigenous infants.

^(e) Mortality rate for Indigenous infants minus the mortality rate for non-Indigenous infants.
