Harmonisation and classification zone - ONS: Harmonised concepts and questions
The SQB is working with the ONS Classification and Harmonisation Unit to promote comparability in surveys by providing users with information on harmonised standard questions along with an easy means of tracking their use in major social surveys. The collaboration aims to provide greater visibility of the questions, encouraging their re-use not only to increase comparability across data sources but also to increase efficiencies in survey design by reducing the resources required to develop new surveys.
These web pages will initially focus on the Primary set of harmonised concepts and questions. Later, we will develop content for the Secondary set.
