QUEENSLAND

MEDIAN AGE

• At June 2017, the median age (the age at which half the population is older and half is younger) of Queensland's population was 37.1 years, up from 36.6 years at June 2012. The median age of males in 2017 was 36.4 years compared with 37.9 years for females.

• The median age of the population in Greater Brisbane was 35.3 years at June 2017, up slightly from 35.0 at June 2012, while the median age in the rest of Queensland increased from 38.2 to 39.2 years over the same period.

• The SA2 with the highest median age was Bribie Island (59.6 years) in the Moreton Bay region. This was followed by Cooloola (58.5) in the Wide Bay region, and Redland Islands (56.1) in Brisbane's east.

• The two SA2s with the lowest median ages had predominantly Aboriginal and Torres Strait Islander populations. These were Northern Peninsula (22.4 years) in the far north of the state and Yarrabah (22.7) near Cairns. Other SA2s with comparatively low median ages included St Lucia (23.9) in Greater Brisbane and Douglas (24.6) in Townsville. This reflects large numbers of university students in these areas.
