The Australian and New Zealand Standard Research Classification: Fields of Research allows research and development (R&D) activity to be categorised according to the methodology used in the R&D, rather than the activity of the unit performing the R&D or the purpose of the R&D. The categories in the classification include major fields and related sub-fields of research and emerging areas of study investigated by businesses, universities, tertiary institutions, national research institutions and other organisations. This classification allows the categorisation of fields of research activity within Australia and New Zealand.
