Classifying UK charities’ activities by charitable cause: a new classification system

This article presents a new system for classifying UK charities’ activities according to their charitable purposes. It also outlines our attempts to use keyword search rules to apply these classifications to the various UK charity registers. The classification results and code, which are made freely available online, help to address the limitations of existing classification schemes in the UK context. Depending on the scheme, these include a lack of detail and coverage of important subsectors, a lack of systematic data collection and limits on the number of classifications per charity. We discuss the pros and cons of different approaches and show that the keyword searching method provides a sufficiently accurate and transparent approach. We also present some preliminary results on how commonly each ‘tag’ is matched against UK charities, as well as exploring how the results compare to existing classifications in the register of charities for England and Wales.
