The sexual identity question is now a national harmonised standard. It is important that the question is asked in a consistent way on all social surveys, for comparability across different sources. In view of this, a user guide has been developed to assist researchers. The evidence from the various stages of the project have been consolidated into one document with the aim of providing guidance to both users of sexual identity statistics and those organisations collecting data on sexual identity. ‘Measuring sexual identity: A guide for researchers’ was published in May 2009.
