City of Joondalup

Resident workers (Regional) - Individual income quartiles

In the City of Joondalup, the 'medium highest' quartile is the largest group, comprising 26% of regional labour force.

Individual Income is an indicator of socio-economic status, skills and occupations required in a particular industry. With other data sources, such as Qualifications and Occupation, it helps to evaluate the economic opportunities of people in an industry.

Income quartiles are used to condense income categories into manageable units, adjust for the effects of inflation, and allow areas to be compared over time relative to a benchmark. The incomes for the state are split into four equal groups, each containing 25% of the regional resident workers, and the quartiles allow users to compare changes in the local area to changes statewide, or against another benchmark. For more information on how quartiles are calculated please refer to the data notes.

As well as being related to the type of jobs and qualifications required in a particular industry, income levels can be related to the level of part-time employment, Occupation, Qualification and the Age structure of the regional labour force, so the data should be looked at in conjunction with these topics.

The City of Joondalup resident worker region is defined by an area in which a significant percentage of workers travelled into the City of Joondalup to work at the 2011 Census.
