Definition

Estimated resident population at the end of the quarter: 31 March, 30 June, 30 September or 31 December.

Available for Australia and its states and territories from the Australian Bureau of Statistics. The reference date differs from the annual 1 January or 1 July dates in population, so the two are not comparable. The ABS states that all data after 30 June 2021 are subject to revision.
