Summary
Population figures just published by the
Australian Bureau of Statistics show that the total Estimated Resident
Population of the Northern Territory reached 245,657 at the end of September
2016, an increase of 812 over one year earlier. This represents a growth rate
of 0.3%. The population of 245,657 gives the Territory a 1.0% share of the
national population of 24,220,192.
The graph below illustrates how the
Territory’s population has changed over the last few years. Following strong
increases in 2012 and early 2013, population growth has been limited over the
most recent years.

The bar chart below shows how the
Territory’s population growth rate over the year to 30th September 2016
compares with that of the other States and Territories. Relative to other
jurisdictions, the Territory’s population growth rate is quite low.

What factors are driving population change in the Territory?
Population change in the Territory is the result of several demographic processes. These are:
- births
- deaths
- in-migration from interstate
- out-migration to interstate
- immigration from overseas
- emigration to overseas.
These six factors are often summarised as:
- natural change (births minus deaths)
- net interstate migration (in-migration from interstate minus out-migration to interstate)
- net overseas migration (immigration minus emigration).
The diagram below shows how these factors of population change affected population growth over the year to 30th September 2016. Processes which remove people from the Territory are shown in red; those which add people to the population are shown in green.
Over the year to 30th September 2016 there were 3,950 births and 1,090 deaths to Territory residents, giving natural change of 2,860. There were an estimated 14,651 in-migration moves to the Territory from interstate, while there were 17,455 out-migrations to other parts of Australia. Net interstate migration was -2,804. The Territory’s population experienced immigration of 5,641 from overseas, while emigration to other countries was 4,885. Net overseas migration was 756. Natural change, plus net interstate migration, plus net overseas migration equals total population change, which was 812. Although overall population change was modest, the churn of population (numbers of people being added and removed from the population) was substantial. This is a long-established characteristic of the Territory’s demography.

Factors affecting population change in recent years
Much of the volatility in the
Territory’s population growth over the years is due to fluctuations in
migration, which in part reflects fluctuations in the Territory’s economy. The
graph below shows how natural change, net interstate migration, and net
overseas migration have varied on a quarterly basis in recent years. The slow
growth of the Territory’s population over the last few years is due to net
interstate migration losses and lower levels of net overseas migration.

are quarters of the year; e.g. “Qtr 1 2016” refers to the first quarter of 2016
