Office for National Statisitics - Sexual Orientation, UK: 2017

Paula Guy, Population Statistics Division, Office for National Statistics said:

 "We estimate that 4.2% of people aged 16 to 24 years identify as lesbian, gay or bisexual, a higher proportion than for other older age groups. Around 7 in 10 of the lesbian, gay or bisexual population are single and have never married or registered a civil partnership. This reflects the younger age structure of this population and that legal unions for same-sex couples are relatively new.”
