The 2021 Census captured Perth mid-pandemic. Population growth, changing household sizes, and income divergence between suburbs tell the story.
The 2021 ABS Census was conducted in August 2021, more than a year into the pandemic. For Perth, which experienced one of the lowest case rates of any Australian city during that period, the census captured a relatively normal snapshot — but with some notable shifts.
Population growth in Perth's outer northern and southern corridors continued strongly. , , and all grew substantially between 2016 and 2021. Inner suburbs showed more modest growth, with some established areas actually declining slightly as housing stock stayed constant.
Household incomes diverged. The western corridor suburbs — , , — recorded median weekly household incomes well above the Perth average. Eastern corridor suburbs, while growing, saw slower income growth.
Median age statistics reveal a clear spatial pattern. Established inner and western suburbs skew older (median age 38–45). The growth corridors in the outer north and south skew younger (median age 30–35). This reflects the life-stage of residents: younger families buying their first homes in new estates.
The demographics score in our platform combines median income, median age, household size, and tenure mix (owned vs rented). A balanced demographic profile — moderate income, mixed age, mixed tenure — scores well, rather than simply rewarding high-income areas.
