Size of the LGBT population
Ipsos conducted a survey in 27 countries in 2021
According to Gallup, 4.5% of adults in the U.S. identified as LGBT in 2017. 8.2% among Millennials
Increase to 5.6% in 2020 (Gallup): 15.9% among Generation Z, 9.1% among Millennials
Increase to 7.1% in 2021 (Gallup): 20.8% among Generation Z, 10.5% among Millennials
Increase to 7.2% in 2022 (Gallup): 19.7% among Generation Z, 11.2% among Millennials
Increase to 7.6% in 2023 (Gallup): 22.3% among Generation Z, 9.8% among Millennials
Increase to 9.3% in 2024 (Gallup): 23.1% among Generation Z, 14.2% among Millenials
Official statistics have been released in the UK (2021 Census), Canada (2021 Census), Australia (ABS 2022), and New Zealand (2023 Census)
Older estimates:
Society at a Glance (OECD, 2019) collects several LGBT indicators in developed countries.
Stephens-Davidowitz (NYT, 2013) uses different Internet data sources to estimate that around 5% of American men are gay
Fisher et al. (Demography, 2018) estimate that around 0.48% of all US joint tax filers in 2015 were same-sex couples
According to Flores et al. (Williams Institute, 2022), approximately 0.5% of adults in the United States (1.3 million individuals) identify as transgender
Spizzirri et al. (Scientific Reports, 2021): almost 2% of individuals identify as transgender or non-binary in Brazil
Mishel (JOS, 2020): 20% of women and 10% of men aged 15–45 would comprise the LGB community if it were defined to include those who report gay/lesbian or bisexual identity, any same-sex attraction, or same-sex sex
Additional estimates from Ireland in Ceatha et al. (PRPR, 2023), from Austria in Teufl et al. (PGPH, 2025), from the US in Chandra and Nugent (Handbook, 2025)
Hu and Denier (Demography, 2023) look at how sexual orientation changes over the lifecycle in the UK: 6.6% of respondents changed their reported sexual orientation between 2013 and 2019. And it is not only young people who change their self-reported sexual orientation, so no evidence that it stabilizes in adulthood.
See also Hansen et al. (LGBT Health, 2024) documenting changes in both sexual orientation and gender identity over the life course.
See Silva (S&S, 2025) for a deep discussion on sexual identities, including heterosexuals report same-sex attraction and secondary identities such as bear or butch
See Carroll (Handbook, 2025) for an introduction to the demography of asexuality and aromanticism

Genetics and other causes of sexual orientations
Preliminary studies in the '90s using small samples
Hamer et al. (Science, 1993): high rates of same-sex orientation in the maternal uncles and male cousins of homosexual men. They also isolated a relationship with the Xq28 region on the X chromosome
Hu et al (Nature, 1995) found a similar linkage between sexual orientation and chromosome Xq28 in males (but not in females)
Rahman (N&BR, 2005): fraternal birth order effect on male sexual orientation
Långström et al. (ASB, 2010) use twins in Sweden. Genetic effects explained 34-39% of same-sex sexual behavior in men, 18-19% in women
Ganna et al. (Science, 2019): genetics could eventually account for an upper limit of 8 to 25% of same-sex sexual behavior of the population. However, they only manage to explain 1%. Summary by Mills (Science, 2019)
Ablaza et al. (JSR, 2022) re-examine the fraternal birth-order effect (supported) and the female-fecundity effect (not supported) using admin data from the Netherlands. See related comments and replies (Blanchard, JSR 2022; Semenyna et al., JSR 2022; Kabátek et al., JSR 2022)
Kabátek and Blanchard (ASB, 2024): older brothers increased the odds of homosexuality in both men and women in the UK, and older sisters increased the odds in men. Neither older brothers or older sisters affected the odds of bisexuality or asexuality in men or in women
Labor market
Meta-analysis by Klawitter (Industrial Relations, 2015): most studies show that gay men earn less and lesbians earn more than their heterosexual counterparts. See also Ozeren (Procedia, 2014), Drydakis (IZA WoL, 2019; JPopulEcon, 2021; Elgar, 2023), Waite et al. (PLOS ONE, 2019), Weichselbaumer (Handbook, 2022), Martínez (LATAM, 2025), Engin et al.

See Badgett et al. (JEP, 2021); Jepsen and Jepsen (Labour Economics, 2021) for a general discussion on wage gaps in the US over time
Martell and Hansen (RSE, 2017) emphasize the differenze between sexual orientation and sexual behavior proxies
Aksoy et al (ILR Review, 2018) replicate the lesbian advantage and gay male penalty in couples-based comparisons but show that these effects are absent in similarly specified models of non-partnered workers. They also find evidence of a penalty for bisexual workers

Data
Data limitation and methods
Black et al. (Demography, 2000) discuss available data sources and potential measurement errors. See Schönpflug et al. (Feminist Economics, 2018) for a discussion on data in Europe
Martell (Economics Letter, 2021) studies the impact of inferring sexual orientation identity via membership in a same-sex household.
Kühne et al. (JOS, 2019): self-reported and partnership-inferred sexual orientation are not mutual substitutes, instead leading to substantively different conclusions about differences between heterosexuals and sexual minorities
Julian et al. (Demography, 2025): individuals who identify as bisexual and individuals with another/multiple sexual identities often have partners who identify as heterosexual. Therefore, the prevalence of sexually diverse partnerships is distinctly higher when accounting for the sexual identity of both partners than when relying solely on one partner’s sex or identity
See also Julian et al. (JoMF, 2024) for a discussion of how same-sex couples are identified in several US surveys (ACS, CPS, Pulse, NHIS, and NCHAT)
Misclassification
Main issue: a low rate of random error in a large group (opposite-sex couples) may lead to miscalculations in the estimates of a small group (same-sex couples). Because of errors in the sex variable, several same-sex couples may actually be mis-identified opposite-sex couples
Evidence of such measurement error has been found by Black et al. (CCPR, 2007); O’Connell and Gooding (Census, 2007); O’Connell and Feliz (Census, 2011), although the exact magnitude of such error is unclear. See also the related FAQ (Census, 2013) and Goodnature and Neto (JRAP, 2021)
Lewis et al. (Census, 2015) discuss sex and relationship mis-reporting in the American Housing Survey
The U.S. Census Bureau adopted several changes between 2007 and 2008 in order to reduce measurement errors in the American Community Survey. First, it introduced processing and editing changes. Second, it implemented formatting changes to the questionnaire. Thanks to these reforms, there was a significant reduction in the mis-reporting of sex (Kreider and Lofquist, Census 2015).
Banens and Le Penven (Population, 2016) discuss sex mis-coding in France
The U.S. Census Bureau has started introducing the relationship options “opposite-sex’ or “same-sex” marriages and unmarried partnerships in the 2017 CPS, 2019 ACS, and the 2020 Decennial Census. Manning at al. (Demography, 2021): the new relationship categories lead to identify different same-sex couples in terms of demographic characteristics when compared to previous surveys.
Imputations
In the 2000 and 2010 Census, the partner who reported being a spouse of the household head was changed to unmarried partner if the two individuals had the same sex. The American Community Survey had a similar procedure until 2013
In the 1990 Census, the relationship category remained the same (spouse), but the sex of the partner was changed in cases in which the household head and the spouse had the same sex
Current Population Survey: until 2010, same-sex married couples were imputed as opposite-sex married couples. Between 2010 and 2018, same-sex married couple were imputed as same-sex unmarried couple. See also Edwards and Lindstrom (Census, 2017)
See this detailed timeline of how and when same-sex couples have been recorded and imputed in surveys conducted by the U.S. Census

The White House also released a guide in 2023 to collect SOGI data
The report notes that there may be some concern that adding SOGI questions to a survey will cause respondents to skip questions or abandon the survey altogether: but current surveys collecting SOGI data show that respondents are unlikely to skip SOGI questions, especially compared to other sensitive data items. See also the 2023 report by the US National Science and Technology Council, Fredriksen-Goldsen and Kim (RoA, 2015), Cahill et al. (PLoS ONE, 2014), Katz-Wise et al. (PM, 2024)
Bates et al. (JOS, 2019) find no evidence that sexual minorities might be at hard-to-survey population in the 2020 U.S. Census
Ellis et al. (US Census, 2018): most respondents do not find SOGI questions difficult or sensitive to report for themselves or for others in their households , and few raised objections to these questions in the context of the Current Population Survey
Boehmer et al. (MedicalCare, 2024) looks at trends in response patterns to SOGI questions in the BRFSS
Julian et al. (Demography, 2024): younger birth cohorts are more likely to select “something else” for their sexual identity and “none of these” for their gender identity
Hansen et al. (JSSM, 2025): no significant relationship between response order ("lesbian or gay" before/after "straight, that is, not lesbian or gay") and sexual orientation. Young adulthood was predictive of "don’t know" responses, indicating that don’t know responses may capture sexual fluidity, change, or uncertainty
