Darwin had the youngest population of Australian state and territory capital cities in 2023, while Adelaide had the oldest, according to new population data released by the Australian Bureau of Statistics on Thursday.

The statistics show that cities tend to be younger hubs than the regions, while mining, military bases, universities and prisons heavily influence the demographic picture in some areas.
