RDA Northern Territory

Individual income quartiles

In the RDA Northern Territory, the 'medium highest' income quartile was the largest group in 2011, comprising 25% of people aged 15 and over.

The RDA Northern Territory'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.

A detailed explanation of how Individual 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?'

Gross amount for persons aged 15 years and over
