AGE AND SEX DISTRIBUTION
  • The following graph (called a 'population pyramid') compares the age/sex structure of the population residing in greater capital cities with the population residing in the rest of Australia. Each dark bar illustrates the percentage contribution of a sex and five-year age group to the total population of capital cities, while each light bar illustrates the percentage contribution to the rest of Australia's population. For example, the graph shows that in June 2016, males aged 0 to 4 years made up 3.4% of the population of the combined capital cities compared with 3.2% of the rest of Australia.
  • A distinctive feature in the age distribution of Australia at June 2016 was the higher representation of people aged 20 to 44 years residing in capital cities. People in this age group represented 38% of the combined capital city population, compared with 30% of the population in the rest of Australia. This reflects the attraction of younger adults to education, employment and other opportunities in capital cities. In contrast, older adults aged 45 years and over made up a smaller proportion of the population in capital cities (37%) than in the rest of Australia (45%).
  • The population pyramid also highlights differences between the sexes. For June 2016, the most notable feature was the higher proportions of females than males in the older age groups. This was evident in both capital cities and in the rest of Australia. The difference was most marked among the population aged 85 years and over, and is attributable to the longer life expectancy of female Australians.
