The Kinsey scale invented in the 1940s placed people on a range of sexual preferences from exclusively heterosexual at 0 to exclusively homosexual at 6.

In the YouGov study, individuals were asked to put themselves on that sexuality scale. In total, 72% of the British public scored themselves at the completely heterosexual end of the scale, while 4% were at the completely homosexual end, with 19% stating they were somewhere in between – classed as bisexual by Kinsey.

One of the most striking findings of the new study is that with each generation, people see their sexuality as less fixed and more fluid. The results for 18-24 year-olds are particularly telling, with 43% placing themselves in the non-binary area between 1 and 5 and 52% place themselves at one end or the other. Of these, only 46% say they are completely heterosexual and 6% as completely homosexual.
