### Population Growth & Distribution

Z-Score−0.1883σPeriodQ1 2026Position49.4 of 175 qtrsVintage2026-Q4

1Node Definition
Population Growth & Distribution (21410) measures how fast Australia’s population is growing: growth over the year in estimated resident population, in per cent. Higher readings mean faster growth, and more people to house. It is a component of the APN Aggregate Demographic Index™ (21400), at a weight of 0.25.

Known limitations
**Measure change, October 2026.** Until October 2026 this node read the level of the population. A population level rises almost every quarter, so its position measured the date rather than conditions; the node now reads the rate of growth, and the level is shown as context. Estimated resident population is revised at each Census rebasing, and recent quarters are preliminary. The node reads the national total; growth by state is read in the State & Territory Conditions series (21800).
