What is a Classification?

A classification groups data into meaningful categories. A well constructed classification has categories that are mutually exclusive and exhaustive. Each category of a classification also has a description and a unique code to enable users to identify the category.

Classifications are structured to be hierarchical or flat. Hierarchical classifications range from the broadest, most general categories to the most detailed, specific categories. Flat classifications do not have a hierarchy. Classifications promote data comparability across surveys and they are used in;

  • data collection
  • data processing
  • data presentation
  • data analysis
