Components of population change

The growth of Australia's population is comprised of natural increase (the number of births minus the number of deaths) and net overseas migration (NOM).

The contribution to population growth for the year ended 31 March 2019 was higher from NOM (64.2%) than from natural increase (35.8%).

Natural increase

The preliminary estimate of natural increase for the year ended 31 March 2019 was 139,100 people, a decrease of 2.2%, or 3,200 people, compared with natural increase for the year ended 31 March 2018 (142,300 people).

Births

The preliminary estimate of births for the year ended 31 March 2019 (298,100 births) was lower by 6,900 births from the year ended 31 March 2018 (305,000 births).

Deaths

The preliminary estimate of deaths for the year ended 31 March 2019 (159,000 deaths) was lower by 3,800 deaths from the year ended 31 March 2018 (162,700 deaths).


Net overseas migration

For the year ended 31 March 2019, Australia's preliminary net overseas migration (NOM) estimate was 249,700 people. This was 4.9% (11,700 people) higher than the net overseas migration estimated for the year ended 31 March 2018 (238,000 people).

NOM arrivals increased by 1.4% (7,500 people) between the years ended 31 March 2018 (527,200 people) and 31 March 2019 (534,700 people).

NOM departures decreased by 1.4% (4,200 people) between the years ended 31 March 2018 (289,200 people) and 31 March 2019 (285,100 people).

The preliminary NOM estimate for the March quarter 2019 (86,600 people) was 1.7% (1,500 people) higher than the March quarter 2018 (85,100 people).


States and territories

At the state and territory level, population growth has three main components: natural increase, net overseas migration (NOM) and net interstate migration (NIM).

Although majority of states and territories experienced positive population growth in the year ended 31 March 2019, the proportion that each of these components contributed to population growth varied between the states and territories.

For the year ended 31 March 2019, natural increase was the major contributor to population change in Western Australia. Net interstate migration loss was the largest component of population change in the Northern Territory. NOM was the major contributor to population change in New South Wales, Victoria, Queensland, South Australia, Tasmania and the Australian Capital Territory.

NIM gains occurred in Victoria, Queensland, Tasmania, and the Australian Capital Territory. All other states and territories recorded net interstate migration losses.
