Knoxfield
Equivalised household income
Assuming all households were the same size, the 'medium lowest' quartile was the largest income group in Knoxfield in 2021.
While Household Income is a useful measure, it is difficult to tell if changes over time and between geographic areas are due to actual changes in income levels, or due to changes in household size and composition. For example, an increase in lower income households could be due to job losses in key economic sectors, or simply due to decreasing household size as adult children leave home.
Equivalised Household Income puts all households on an equal footing independent of household size and composition to enable a true comparison between areas and over time. It is an indicator of the income resource available to a household of standard size and is the best measure of the changing economic fortunes of households living in Knoxfield.
A detailed explanation of how Equivalised Household Income quartiles are calculated and interpreted is available in specific data notes.
