"23 percent of Brits identified as somewhere from one to six; that is, as something other than exclusively heterosexual. But the results get really interesting when you sorted by age. About half of British youth from 18 to 24 identified as within that one to six range on the Kinsey scale:
What's interesting is that, of the respondents who scored themselves as something other than zero ("exclusively heterosexual"), most of them did not pick six ("exclusively homosexual") but rather selected something in between. Indeed, one and two were among the most popular responses. That seems like a pretty significant rebuke to our cultural norm of classifying people as categorically "straight" or "gay.""
Another article referencing the same polling info,
"The YouGov poll found that 78 percent of all Americans are totally heterosexual, but only 64 percent of people between the ages of 18-29 were. Curiously, only 4% stated they were totally gay – bisexuality makes up a much larger portion of American sexuality. In this group the bulk (10%) say that they are more heterosexual than homosexual while 3% put themselves in the middle and another 3% say that they are predominantly homosexual. Of those who considered their sexuality along a spectrum, 9% said they were closer to full heterosexuality (level 1), while 1% considered themselves almost completely homosexual (level 5 on the scale). 12% of heterosexual American adults say that they have had a sexual experience with someone of the same sex.
YouGov posted the results of a similar British study earlier this week that found that half of respondents aged 18-24 identified as non-heterosexual.
When it comes to bisexuality, 24 percent of Americans, ages 30-44, claim to be on that scale, but only 8 percent (or less) of people over 45 years old would classify themselves that way. For straight women, 15% have had a same-sex experience."
