What drives population change?

Births and deaths set natural change. Net migration can reinforce, reduce, or reverse that direction.

Migration contribution Adds to growth

Positive net migration adds to natural growth.

Australia, 2024 projected: natural change +125,003 people, net migration +138,510, WPP adjustment +5, total population change +263,518. Positive net migration adds to natural growth.

Exact reconciliation: WPP includes a +5-person statistical adjustment. Figures are rounded to whole people.
