A study of 8,337 British men found that 6.1% have had a "homosexual experience" and 3.6% had "1+ homosexual partner ever."
HM Treasury and the Department of Trade and Industry completed a survey to help the government analyse the financial implications of the Civil Partnerships Act (such as pensions, inheritance and tax benefits). They concluded that there were 3.6 m gay people in Britain—around 6% of the total population or 1 in 16.66 people.
In an online survey carried out among over 75,000 Yougov panel participants in Britain, 90.9% identified as heterosexual, 5.8% as gay, lesbian or bisexual, 1.3% opted not to give an answer, and 2.1% gave other reasons. Though the panel is not a probability sample, it was recruited to ensure that it closely matched the overall British population on demographic variables such as age, gender, employment status and socio-economic classification. Ethnic minorities were less likely to identify as gay or lesbian than Whites (1.4% vs. 3.5%) but were more likely to say they prefer not to disclose their sexual orientation (7.5% vs 0.9%). More LGB than heterosexual respondents indicated they would be less likely to disclose their true sexual orientation in a face-to-face interview than in a self-administered, online survey.
A representative survey of 238,206 Britons, exclusive to their categories, found 1% identified as gay or lesbian and 0.5% said they were bisexual. A further 0.5% self-identified as "other", and 3% responded as "do not know" or refused to answer. In total this adds up to 5% of people who do not identify as heterosexual, or alternatively 98.5% who do not identify as either gay, lesbian or bisexual. Ben Summerskill, chief executive of the gay equality charity Stonewall stated: "This is the first time that people were asked and data collection happened on doorsteps or over the phone, which may deter people from giving accurate responses - particularly if someone isn't openly gay at home." Stonewall worked with 600 major employers and their experience had shown that these statistics increased when people were regularly asked about sexual orientation as part of general monitoring information.
The Integrated Household Survey, produced by the Office of National Statistics, gives the following figures for the period April 2011 to March 2012:
93.9 per cent of adults identified themselves as Heterosexual/Straight. 1.1 per cent of the surveyed UK population, approximately 545,000 adults, identified themselves as Gay or Lesbian. 0.4 per cent of the surveyed UK population, approximately 220,000 adults, identified themselves as Bisexual. 0.3 per cent identified themselves as "Other". 3.6 per cent of adults stated "Don't know" or refused to answer the question. 0.6 per cent of respondents provided "No response" to the question. 2.7 per cent of 16- to 24-year-olds in the UK identified themselves as Gay, Lesbian or Bisexual compared with 0.4 per cent of 65-year-olds and over.
