Each occupation in ANZSCO is defined by its primary tasks. Each occupation’s definition may also include alternate titles for the occupation as well as note specialisations.
Information on industries and sectors is captured using a separate classification system, the Australian and New Zealand Standard Industrial Classification (ANZSIC). ANZSIC is used to classify the activity of organisations undertaking productive activities such as businesses, companies and not-for-profit organisations. It enables information about businesses, including employee data, to be grouped by reference to their industry and supports comparisons between industries.
Some occupations are unique to an industry or sector, for example, shearer is an occupation that is unique to the agriculture sector while miner is unique to the mining industry. Other occupations, such as accountant and human resource manager, are common to multiple industries or sectors. These occupations can only be aligned to a specific industry or sector if there are underlying tasks and skills which are distinct to that industry. Box 1 shows how some occupations in ANZSCO are defined.
Data on the number of people undertaking a particular occupation are only captured at the 6-digit occupation level. Data are not able to be further delineated to show the number of people that are undertaking a specialisation nor an occupation that is included in a catch-all ‘nec’ (not elsewhere classified) category. To ensure that all occupations are represented in the ANZSCO, some which do not meet the threshold for the number of people undertaking them are gathered into catch-all ‘nec’ (not elsewhere classified) categories across the classification.
