SEX RATIO
  • At June 2017, the sex ratio of Tasmania was 98.0 males per 100 females, down from 99.2 in 2012. The sex ratio was slightly higher in Greater Hobart (99.2) than in the rest of Tasmania (97.1).
  • Risdon Vale, in Hobart's north-eastern suburbs, was the SA2 with the highest sex ratio (128.1 males per 100 females) due in part to the male population of Risdon Prison. The next highest sex ratios were in Derwent Valley (114.7) and Central Highlands (114.6).
  • The lowest sex ratios were in South Launceston (86.3 males per 100 females), Newstead (86.5), an inner suburb of Launceston, and Devonport (87.2) on Tasmania's north coast.

AGE AND SEX DISTRIBUTION
  • The age distribution of Tasmania's population at June 2017 was characterised by a lower proportion of people aged 20 to 44 years (29%) than the Australian population (35%). This in part reflects a net outflow of young adults from Tasmania to pursue education and employment opportunities interstate. Tasmania also had a higher proportion of people aged 45 years and over (47%) than Australia as a whole (40%). This partly reflects a trend of adults in this age group moving into the state.
