City of Knox

Life-stages - Household income quartiles

In the City of Knox, 41.2% of children aged 0 to 4 years in households with income were in the 'medium highest' quartile.

Households form the common 'economic unit' in our society. The City of Knox's Household Income is one of the most important indicators of socio-economic status. When related to age, this shows the household income of the household in which the individual of that age group was counted.

This helps to reveal the socio-economic opportunities available to people of a particular age group, and the resources available to them. It can answer questions such as whether the wealth of an area is being shared equally among all ages, or particular groups, eg. children or retirees, have access to significantly higher or lower incomes than the general population.

Note that, particularly for children, this does not mean that the person in the age group actually receives the income, just that they are in a household with that income.

The incomes presented on this page are in quartiles, which are defined as four groups containing an equal number of households across Victoria. They may not contain an equal number of persons in each group, and in fact, more people are generally counted in households in the highest income quartile because income is correlated with household size. However, using income quartiles effectively adjusts for inflation, allowing changes in income for the chosen life stage to be benchmarked to the state, the wider population, and shows change over time. A detailed explanation of how Household Income quartiles are calculated and interpreted is available in specific data notes.

Derived from the Census question:

'What is the total of all wages/salaries, government benefits, pensions, allowances and other income the person usually receives?'
