Every semester, students in my Human Sexuality course ask me what percentage of the population is gay or lesbian. Before answering this question, I usually give the class an opportunity to guess. Although this invariably leads to a wide range of responses, the most frequent number that comes up is 10%, and many students who cite this statistic are convinced that it is a fact. But are they right? Probably not.
The 10% statistic comes from research conducted by Alfred Kinsey in the 1940s, in which he found that 10% of the men in his sample were gay. However, Kinsey’s participants were not representative of the overall population (for one thing, they were all White and most lived in big cities). He also oversampled from the gay community.
Thus, we have to view his findings with a bit of caution. More recent research employing better sampling methods has reliably found that the number of sexual minorities in the population is a bit smaller.
Before we get into specific numbers, please be aware that this is a difficult question to answer for several reasons. First, researchers get different numbers depending upon how they define “sexual orientation”—is it a label/identity, or is it a behavior? This is a major issue because sexual labels and behaviors do not always match up.
For example, there are many men who self-identify as heterosexual, but who have sex with other men on the “down-low.” Generally speaking, the percentage of people who identify as gay or lesbian tends to be lower than the percentage of people who have ever had sexual contact with a member of the same sex.
Second, when you survey people about their sexual orientation and sexual practices, not everyone is honest, which biases the results (e.g., some gay and lesbian people might be afraid to report their true sexuality because they are not comfortable with their identity or have concerns about being outed).
With this in mind, let’s look at the results from two nationally representative surveys conducted in the United States. The first study, originally reported in 1994, found that 2.8% of men and 1.4% of women identified as homosexual.[SUP]1[/SUP]
The second study, reported in 2010, found that about 8% of men and 7% of women identified as gay, lesbian, or bisexual.[SUP]2[/SUP] How do we explain the large discrepancy between these studies? Are there more gay people now than there were in the 1990s? That seems unlikely. The higher numbers in the more recent survey probably reflect the fact that sexual minorities simply feel more comfortable disclosing their sexual identities in a day and age when homosexuality is more socially accepted. The newer numbers are also higher because they collapsed across all non-heterosexual identities (gay,bisexual, and other).
In light of these findings, it is interesting to note that most people significantly overestimate the number of gays and lesbians who are out and about in the world. For instance, a 2011 Gallup poll found that, on average, Americans’ estimated that 25% of the population is homosexual.[SUP]3[/SUP] It is not clear why people's estimates differ so much from what researchers have documented.
In short, although we cannot say with certainty what percentage of the population is gay, the best available scientific evidence suggests that the numbers are probably a little lower than most of us think.
Well I have to admit that I always thought it was 10% or higher. Not that it matters mind you.
Although a gay friend of mine when asked this question said too me that if all the gay people were coloured red for one day you would be amazes at how many red people you would see in the course of your average day. Maybe he was biased though come to think of it.
