The preliminary estimated resident Indigenous population has a much younger age structure than the non-Indigenous population. At 30 June 2006, there were more Aboriginal and Torres Strait Islander people in younger age groups compared with older age groups and the median age of the Indigenous population (the age where half the population is younger) was 21 years. In contrast, in the non-Indigenous population, there were more people in the older age groups compared with the younger age groups, and the median age was 37 years.
Children aged under 15 years comprised 38% of the total Indigenous population (compared with 19% in the non-Indigenous population); people aged 15-24 years comprised 19% of the Indigenous population (compared with 14%) and people aged 65 years and over represented only 3% (compared with 13%). These different age profiles reflect the higher rates of fertility and deaths occurring at younger ages among the Aboriginal and Torres Strait Islander population.
