Estimated resident population by sex and age, quarterly

abs/population-quarterlyby Australian Bureau of Statistics www.abs.gov.auAPI readyCurrent release

Country or region: Australia

The quarterly estimated resident population (ERP) of the Australian Bureau of Statistics by sex and age: one row per sex, age, state or territory and quarter, from the September quarter 1981, for Australia and each state and territory. Ages are single years from 0 to 100 (where 100 covers 100 years and over), five-year groups, 85 years and over, and all ages. Each estimate is the population in persons at the end of its quarter: the March quarter 2026 is the population at 31 March 2026. The ABS's annual changes in the population are left out (they follow from the estimates), and its components of change (births, deaths and migration) are the companion dataset abs/population-components. The Data API is an ABS beta service whose data can trail the ABS website.

Access paths

by_region (ordered by region, age, sex, period): filter region with = or [in].
by_period (ordered by period, region, age, sex): bound period on both sides.
A query that uses none of these is refused with its required filters.

Bind: filter with = or [in] to use the layout ordered by it. Range: filter with [gt], [gte], [lt] or [lte]. Filter: any filter once a layout is chosen.

Codes that explain a null value: missing, suppressed or not applicable values are null with a status field, never zero.
