No, actually. It does look like that, but I just did some digging. A more robust dataset is the GP Patient Survey, which estimates that between 0.65% and 0.76% of England and Wales' population is trans. That would give us, at the upper end, a total trans population of 395,200. We have no idea of the split between trans men and trans women because the only effort to find out was a really bad question in a census, but it's split pretty evenly in America - there's 3% difference between trans women and trans men over there, with slightly more trans women. So if we assume slightly more than half of that trans-identifying population identify as women, that would give us about 209,000 trans women.
Taking that back to your prison chart, 92 prisoners for sexual offences out of population of 209,000 would give us a 440 trans women perpetrators per million figure. I can't remember what the smoking gun chart had to say in terms of the per million figure for men, but if we base it on 15,000 male convicts (see below for maths), it gives us 460 men per million. About the same, not more.
But that assumes that every trans woman and every man are arrested, prosecuted and convicted for their crimes. We don't have the figures for trans women because the data aren't reported accurately or consistently. There's more information out there for men.
Only around 3% of reported rapes in the UK result in prosecution.
Around 64% of that 3% result in conviction and imprisonment.
There are currently around 15,665 people in prison for sexual offences, and nearly all are men - let's assume 15,000, for a round number.
Not all of those men are in for rape — some will be for other sexual offences.
Let’s conservatively assume 30% of sexual offence prisoners are in for rape.
30% of 15,000 = 4,500 rapists in prison.
64% of rape prosecutions result in conviction - 4500/0.64 gives us 7,031 prosecutions.
3% of rapes lead to prosecution - 7,031/0.03 gives us 234,367 rapes in the UK, against a prison population of 4,500 rapists.
We need to take into account the fact that the vast majority of rapes go unreported. Only about 16 - 18% of women report their rapes. If only 16% report it, that means there are actually 1.4m rapes a year, against our 4,500 prison population. If 18% report, there's 1.1m rapes, against 4,500 prisoners.
Most rapists are multiple offenders. If we assume 2 or 3 rapes per offender, which the figures we have in the UK can reinforce, that's somewhere between 470,000 and 585,000 rapists in the UK, against a population of 4,500 male rapists in prison.
False accusations of rape haven't been factored in and probs should have been, but this is fag packet stuff. It should be noted that the lower estimate of individual male rapists is greater than the total number of estimated trans women in the UK.
And it's just rape. Not all sexual assault. I could run the numbers for that if you like but honestly - without reflecting the wider story around each data point used in the chart, it's junk. Selective use of data to over-emphasise the risk trans women present, and under-emphasis the risk that men present.
Thanks for making me run this exercise. It's reminded me who the real threat to women is.
