Estimated resident population by region (ASGS Edition 3), annual

abs/regional-populationby Australian Bureau of Statistics www.abs.gov.auAPI readyCurrent release

Country or region: Australia

The estimated resident population (ERP) of the Australian Bureau of Statistics for every area of the Australian Statistical Geography Standard (ASGS) Edition 3 down to Statistical Area Level 2: one row per area and year from 2001, for Australia, the states and territories, the Greater Capital City Statistical Areas and the rest of each state, the 89 Statistical Areas Level 4, the 340 Level 3 and the 2,454 Level 2 (suburb-sized areas). Each estimate is the population in persons at 30 June of its year, on the 2021 boundaries for every year. Rows of different levels overlap, so do not add them up across levels. Sex, age and the components of change are not in this dataflow (see abs/population-quarterly and abs/population-components for states). The Data API is an ABS beta service whose data can trail the ABS website.

Access paths

by_region (ordered by region, period): filter region with = or [in].
by_type (ordered by region_type, period, region): filter region_type with = or [in].
Fully scannable: a query that uses none of these reads the whole release, and may sort on any field.

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.
Status field	Code	Meaning	Null fields
`obs_status`	`m`	not recorded	`value`
`obs_status`	`n`	not available for publication but included in totals where applicable, unless otherwise indicated	`value`
`obs_status`	`o`	nil or rounded to zero, including null cells	`value`
`obs_status`	`q`	not available	`value`
