Individual income quartiles

In the Keilor District, the 'lowest' income quartile was the largest group in 2021, comprising 27% of people aged 15 and over.

the Keilor District's income statistics are an indicator of socio-economic status. With other data sources, such as Household Income, Qualifications and Occupation, they help tell the story of the area's economic opportunities and socio-economic status. Individual income levels are not comparable over time because of the influences of economic change such as wage level fluctuations and inflation. The income quartile method is the most objective method of comparing change in the income profile of a community over time.
