Greater Perth is Perth's Greater Capital City Statistical Area (GCCSA), a geographical area designed to represent the functional extent of Western Australia's (WA) capital city.
The labour market is sometimes used as a de facto measure of the functional extent of a city since it contains the majority of the commuting population.
[1] GCCSAs were designed to provide a stable and consistent boundary that reflects the functional extent of each of Australia's capital cities.
[1] Greater Perth consists of an area equivalent to the Perth metropolitan region, as defined by the Metropolitan Region Scheme, plus the City of Mandurah and the Pinjarra Level 2 Statistical Area of the Shire of Murray.
In the year to 2013, the density of Greater Perth increased by 10 inhabitants per square kilometre (26/sq mi).
