ONS's Sexual Identity Project aimed to develop questioning that could be used on social surveys and for equality monitoring purposes. It was important that questioning was developed to meet user requirements, was acceptable to respondents and could be administered on a social survey.
Early testing of potential questions on sexual identity was conducted by trials on the National Statistics Omnibus Survey.
The prototype question was tested by:
- cognitive/in-depth interviews; and
- a General Lifestyle Survey (GLF) split sample pilot
The final question was added to the Integrated Household Survey (IHS) in January 2009. The IHS combines most ONS household surveys into one. Data collected in the first year will be used to produce the first baseline estimates of the size and characteristics of the lesbian, gay and bisexual (LGB) populations.
