WSROC Region

Estimated Resident Population (ERP)

The official population of WSROC Region as of the 30th June 2016, is 1,573,519.

The Estimated Resident Population is the OFFICIAL WSROC Region population for 2016. For areas within the WSROC Region, the ERP is not an official count but an experimental estimate which is subject to review after the next Census.

Populations are counted and estimated in various ways. The most comprehensive population count available in Australia is derived from the Census of Population and Housing conducted by the Australian Bureau of Statistics every five years. However the Census count is generally an under-estimate of the actual population, due to people missed in the Census and people overseas on Census night. To provide a more accurate population figure which is updated more frequently than every five years, the Australian Bureau of Statistics also produces "Estimated Resident Population" (ERP) numbers for the WSROC Region. Estimates for areas within the WSROC Region are based on aggregates of SA1s derived from population distributions applicable at the 2011 Census. Actual populations may vary slightly where population growth has not been uniform since the previous Census.

See data notes for a detailed explanation of different population types, how they are calculated and when to use each one.
