- The proportion of the UK population aged 16 years and over identifying as heterosexual or straight decreased from 95.3% in 2014 to 94.6% in 2018.
- The proportion identifying as lesbian, gay or bisexual (LGB) increased from 1.6% in 2014 to 2.2% in 2018.
- In 2018, there were an estimated 1.2 million people aged 16 years and over identifying as LGB.
- Men (2.5%) were more likely to identify as LGB than women (2.0%) in 2018.
- Younger people (aged 16 to 24 years) were most likely to identify as LGB in 2018 (4.4%).
- Among English regions, people in London were most likely to identify as LGB (2.8%), with people in the North East the least likely (1.8%).
- More than two-thirds (68.7%) of people who identified as LGB were single (never married or in a civil partnership).
“People in their late teens and early twenties are more likely to identify as lesbian, gay or bisexual (LGB) than older age groups.
“Meanwhile, more than two-thirds of the LGB population are single (never married or entered into a civil partnership). This reflects the younger age structure of this population, the changing attitudes of the general population to marriage and the fact that legal unions have only recently been available for same-sex couples.”

In 2018, an estimated 94.6% of the UK population aged 16 years and over (53.0 million people) identified as heterosexual or straight. This represents a continuation of the decrease seen since 2014, when 95.3% of the population identified themselves as heterosexual or straight (Table 1).
|Heterosexual or straight||95.3||95.2||95.0||95.0||94.6|
|Gay or lesbian||1.1||1.2||1.2||1.3||1.4|
|Do not know or refuse||2.8||2.6||2.5||2.3||2.5|

An estimated 2.2% of the population aged 16 years and over (1.2 million people) identified themselves as lesbian, gay or bisexual (LGB) in 2018; this is comprised of 1.4% identifying as gay or lesbian and 0.9% as bisexual (see Table 1, note 3). The proportion of the population identifying as LGB increased from 1.6% in 2014 to 2.2% in 2018 (Figure 1).
A higher proportion of men than women identify as LGB
In 2018, 2.5% of men identified themselves as LGB, compared with 2.0% of women. More than twice the proportion of men (1.9%) compared with women (0.9%) identified as gay or lesbian (Figure 2). Conversely, a higher proportion of women than men identified as bisexual, at 1.1% and 0.6% respectively. This represents a continuation of a trend that has been observed back to 2014, where a higher proportion of men than women identify as gay or lesbian and a higher proportion of women than men identify as bisexual.

In 2018, people aged 16 to 24 years were more likely to identify as lesbian, gay or bisexual (LGB) than other age groups.
People in each successively older age group were less likely to identify as LGB than those in the preceding younger age group in 2018 (Figure 3). Of the population aged 16 years and over, 20.9% of men and 23.4% of women are aged 65 years and over. However, only 6.7% of men and 7.4% of women who identified as LGB were aged 65 years and over. A possible reason for this pattern is that younger people could be more likely to explore their sexuality combined with more social acceptability of different sexual identities and the ability to express these today.

Lesbian, gay or bisexual population by age and sex, UK, 2018 and UK population by age and sex, 2018
In 2018, the percentage of people who identified as lesbian, gay or bisexual (LGB) was similar for England (2.3%), Wales (2.4%) and Scotland (2.0%).
For Northern Ireland, the percentage of people identifying themselves as LGB in 2018 was 1.2%. The UK average in 2018 was 2.2%, which has increased from 1.6% in 2014 (Figure 4).
People in London are most likely to identify as LGB
In 2018, a higher proportion of people in London (2.8%) identified as LGB than in other regions of England. The North East had the lowest proportion (1.8%).
The higher proportion of people identifying as LGB in London may be explained by the younger age structure of the population. The median age of the population in London was 35.3 years in 2018, compared with 41.8 years in the North East of England.
The East Midlands and West Midlands were the regions that saw the largest change in the proportion of people identifying as LGB over the last four years, with both increasing from 2014 to 2018 (from 1.2% to 2.2% and 1.3% to 2.3% respectively).

Among those identifying as lesbian, gay or bisexual (LGB) in 2018, more than two-thirds (68.7%) were single, meaning that they had never married or entered into a civil partnership. This is double the proportion of those who identified as heterosexual or straight and were single (34.2%). A possible reason for this difference is the younger age structure of the LGB population combined with the increase in the average age of marriage.
Furthermore, legal unions for same-sex couples have only become available recently; civil partnerships were introduced for same-sex couples in the UK in December 2005, and same-sex marriage has been available in England, Wales and Scotland since 2014 and in Northern Ireland from 2020.
More couples are choosing to live together before or instead of marriage. Those with a legal marital status of single may live with a partner of the same or opposite sex. Same-sex cohabiting couples are the most common type of same-sex couple family, accounting for just over half of same-sex families in 2019.
From 2014 to 2018, the proportion of people identifying as LGB who were in same-sex marriages increased from 0.8% to 7.3%, while those in civil partnerships decreased from 12.3% to 6.5% (Figure 6). This suggests that since its introduction in 2014, an increasing number of people who identify as LGB are choosing to enter a same-sex marriage rather than a civil partnership or to convert their civil partnership to a same-sex marriage.

Sexual orientation, UK
Dataset | Released 6 March 2020
Sexual orientation in the UK from 2012 to 2018 by region, sex, age, marital status, ethnicity and National Statistics Socio-economic Classification.
“Sexual orientation” is an umbrella term that encompasses sexual identity, attraction and behaviour. It is a subjective view of oneself and may change over time and in different contexts.
The measurement of sexual identity (PDF, 116KB) has been identified as the component of sexual orientation most closely related to experiences of disadvantage and discrimination. Sexual identity does not necessarily reflect sexual attraction and/or sexual behaviour, which are separate concepts not currently measured by the Annual Population Survey (APS).
Sexual orientation categorised as “other”
The “other” category captures people who do not consider themselves to fit into the heterosexual or straight, gay or lesbian, or bisexual categories. It might also include people who responded “other” for different reasons such as those who did not understand the terminology or who are against categorisation.Nôl i'r tabl cynnwys
Sexual orientation estimates are based on data from the Annual Population Survey (APS), which collects information on self-perceived sexual identity from the household population aged 16 years and over in the UK. The household population excludes people living in communal establishments with the exception of those in NHS housing and students in halls of residence (sampled via the private households of their parents).
The estimates presented within this bulletin and the associated datasets for the reference years 2014 to 2018 have been revised and differ from previous publications. The estimates have been revised for two reasons. The first reason is to incorporate the re-weighting of the Labour Force Survey (LFS) and APS. The re-weighting process occurs periodically to take into account the latest population estimates and projections. The second reason is to incorporate an improvement made to the sexual orientation variables on the LFS and APS.
The improvement was made as a result of the detection of an issue in the data collection process relating specifically to the sexual identity question. This issue resulted in an artificially increased number of “don’t know or refuse” responses to interviews carried out by field interviews using a mobile phone. In the past, the number of these interviews was very small, but over time this has increased to try to improve overall LFS response rates. To adjust for this quality issue, we have removed cases where the interview was carried out by a field interviewer using a mobile phone. After removing these cases, we have re-weighted the responses to take into account the smaller sample size and new 2018 weights.
We have made this adjustment for the years 2014 to 2018. Because the variable used to identify field interviews carried out by mobile phone is not available for the sexual orientation data prior to 2014, estimates for the years 2012 and 2013 have not been revised. A comparable time series of estimates is therefore now available back to 2014.
This applies to estimates for the UK, England, Wales and Scotland only. Because Northern Ireland field interviews are all carried out face to face, sexual orientation data for Northern Ireland are unaffected by this. Estimates for Northern Ireland from 2012 to 2017 differ from previously published figures as they have been revised following the re-weighting of the APS, but they have not been subject to any further changes. As previously, a comparable time series of estimates for Northern Ireland is therefore available back to 2012.
Adjustments to future estimates
A solution has been implemented from January 2020, but because of the wave-based design of the survey this does not fully eliminate the presence of cases affected by this from the sexual orientation estimates until 2022. Therefore, in production of the 2019, 2020 and 2021 estimates, we will continue to apply this same adjustment to each new year of data.
More detailed information on the Sexual Identity question and design of the APS is available in the LFS user guide.
Change of terminology
In 2019 (publication of the 2017 data), the terminology in this release changed from “sexual identity” to “sexual orientation” to align with legislation (Equality Act 2010); please see the Glossary for definitions.
Although the terminology changed, the data source and methodology used to produce the estimates were not changed and remained consistent with previous years.
Sexual orientation and Census 2021
The Office for National Statistics (ONS) has recommended a new voluntary question on sexual orientation for those aged 16 years and over for Census 2021 in England and Wales. The data gathered will make it easier to monitor inequalities under the anti-discrimination duties of the Equality Act 2010. Having an estimate of the size of the lesbian, gay or bisexual (LGB) community will allow charities and local and central government to target services effectively. For more information, see the government white paper that was published in December 2018.
National Records of Scotland (NRS) also plan to introduce a new voluntary question on sexual orientation for Census 2021 in Scotland, information about which is available in the NRS Scotland’s Census 2021 Sexual Orientation Topic Report.Nôl i'r tabl cynnwys
Sexual orientation estimates have a number of uses, both direct and indirect, informing policy decisions at a national level. The estimates are mainly used to provide evidence and to inform the monitoring of the Equality Act 2010, alongside providing estimates of the lesbian, gay or bisexual (LGB) population for service providers.
This bulletin presents the sexual orientation estimates as percentages. Estimates of the population numbers and measures of quality (to show the levels of uncertainty associated with survey estimates) are presented in the datasets. Users are advised to consult the quality measures when interpreting the estimates as some estimates are based on a relatively small sample. As a result, these estimates are subject to uncertainty particularly when making comparisons, such as changes from one year to another. In this bulletin, such comparisons are statistically significant unless otherwise stated. This means that there is likely to have been a real change in the underlying population proportions and that the difference we are observing is unlikely to be a result of chance.
More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the Sexual orientation QMI.Nôl i'r tabl cynnwys
