Local workers - Individual income quartiles - All industries
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.
