Standardised mortality ratios (95% confidence interval) of all-cause Indigenous mortality. SMR: standardised mortality ratio. Grey square: 1998-2001, white square: 2002-2005. See Methods for definitions of causes of deaths and remoteness categories. Reference population for calculating standardised mortality ratios: 2001 total Australian population. A standardised mortality ratio equal to 100% means that, compared to the total population, there are no more Indigenous deaths than expected.
