Health indicators are given official codes to aid with identification and interoperability. Many of these codes are based upon different coding principles with some older indicators referencing legacy systems and programmes that were relevant at the onset of data collection, but are no longer in existence today.
Through the preparatory work of data.who.int, and its commitment to data being accessible and understandable, a new, long-term coding approach of Universally Unique Identifiers (UUIDs) is being introduced; producing a long-term, consistent expression for health indicators, with codes ensuring representation is standardized and expressed throughout the entire data journey, within data tables, files, metadata and published assets for sharing and citation.
