ANZSCO is a skill-based classification used to classify all occupations and jobs in the Australian and New Zealand labour markets.
To do this, ANZSCO identifies a set of occupations covering all jobs in the Australian and New Zealand labour markets, defines these occupations according to their attributes and groups them on the basis of their similarity into successively broader categories for statistical and other types of analysis. The individual objects classified in ANZSCO are jobs.
