The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.
Letter from Karen Dunnell, dated May 2009:
As National Statistician, I have been asked to reply to your recent Parliamentary Question on whether the Office for National Statistics' Sexual Identity Project has concluded; and if the most recent report will be placed in the Library (274079).
The ONS Sexual Identity Project formally concluded on 8 May 2009 with the publication of guidance on measuring sexual identity in social surveys and a report on a pilot survey which was used to inform the addition of the sexual identity question on all ONS social surveys in January 2009.
These reports are available on the National Statistics website at the following addresses:
Measuring Sexual Identity: A guide for researchers:
Developing survey questions on sexual identity: Report on the General Lifestyle (GLF) split-sample pilot:
Copies of these reports will be placed in the House of Commons Library.
In addition, ONS is planning to publish experimental statistics on sexual identity in Autumn 2009 with the aim of first national statistics estimates being available in 2010.
