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 a specified industry for the state are split into four equal groups, each containing 25% of the workers in that industry, and the quartiles allow users to compare changes in that industry 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, Occupations, Qualifications and the Age structure of the local workers, so the data should be looked at in conjunction with these topics.
Australian Bureau of Statistics (ABS) – Census 2011 and 2016 – by place of work
Please note – The 2016 Census used a new methodology to “impute” a work location to people who didn’t state their workplace address. As a result, 2016 and 2011 place of work data are not normally comparable. To allow comparison between 2011 and 2016, .id has sourced a 2011 dataset from the ABS which was experimentally imputed using the same methodology. To provide this detail, City of Tea Tree Gully in 2011 had to be constructed from a best fit of Work Destination Zones (DZNs). While it may not be an exact match to the LGA or region boundary, it is considered close enough to allow some comparison. Users should treat this time series data with caution, however, and not compare directly with 2011 data from any other source.
