There were 938 people over the age of 85 living in the RDA Northern Territory in 2016, with largest age group being 25 to 29 year olds.

The Age Structure of the RDA Northern Territory provides key insights into the level of demand for age based services and facilities such as child care. It is also an indicator of the RDA Northern Territory's residential role and function and how it is likely to change in the future.

Five year age groups present a classic age profile of the population. Each age group covers exactly five years, which enables direct comparison between each group.
