The Northern Territory had the highest sex ratio of all the states and territories, followed by Western Australia with 100.5 males per 100 females.

The dependency ratio is the number of children (0-14 years) and aged persons (65 years and over) per 100 persons aged 15-64 years. A reduced value for the dependency ratio indicates that there is a larger population of working age to support the population of non-working age.
The dependency ratio for the Northern Territory at 30 June 2005 was 41.9, compared to 48.6 nationally. The Northern Territory continued to have the second lowest dependency ratio of all the states and territories followed by the Australian Capital Territory (40.5) with the lowest.
