Cardiff Demographics: Population, Age & Income Profile (QLD)

Population data for Cardiff comes from the ABS 2021 Census, the most recent national census. For the most current suburb-level population data, refer to ABS QuickStats or consult the Queensland state government's population projections. Understanding population trends helps home buyers assess housing demand, infrastructure investment, and neighbourhood character.

The median age for Queensland is 38 years according to the 2021 ABS Census, which serves as a reference point for Cardiff. A younger median age often indicates more families and first home buyers, while older demographics suggest established households and potentially lower turnover. Both have implications for property demand and investment strategy.

The median weekly household income in Queensland is $1,310 per week (ABS 2021 Census). Household income affects serviceability for mortgage lending, rental affordability, and the type of housing stock in demand within a suburb. Higher-income areas typically support stronger property values and faster capital growth. Combine demographic research with a climate risk report from ClimateNest for a complete property assessment.
