Left wingers were very upset about this meme about transwomen's astronomical sexual offending rates because they could not read and/or were upset that reality has a known trainphobic bias:
"Sex offending rate of women: 3 per one million
Sex offending rate of men: 395 per million
Sex offending rates of transwomen: 1,916 per million"
So I decided to do all the calculations to spoonfeed them with all the sources and steps provided, so they would have to find new copes to dismiss this reality.
Written questions and answers - Written questions, answers and statements - UK Parliament
"On current offences, in the men’s estate, there were 87 transgender women with a conviction for at least one sexual offence. In the women’s estate, the number of transgender women with a conviction for at least one sexual offence was fewer than 5"
So this is where the original graphic comes up with the number of 92 incarcerated transwoman sex offenders. If you want to be picky, we can use 0 transgender women with a conviction for at least one sexual offence since "fewer than 5" is imprecise, but that won't change the qualitative findings (I will calculate this as well for pedants)
Now for the denominator.
In the England and Wales Census 2021, there were 48,000 who identified as trans women. So that's where we get 92 out of 48,000. And from there, simple multiplication gets us to 1,916 sex offenders per million transwomen.
If we use the figure of 87 from above, we have 1,812 sex offenders per million transwomen, which isn't appreciably lower in terms of magnitude vs the male and female numbers.
For completeness, I shall show the calculations for men and women too.
If you refer to Prison population: 30 June 2021 (linked from Offender Management statistics quarterly: January to March 2021 - GOV.UK), in Table 1.2b, Prison population under an immediate custodial sentence by offence group, age group and sex, you will see that as of 30 Jun 2021, there were 11,660 males in for seuxal offences, and 119 females (the meme is slightly off, but that doesn't change the qualitative conclusions).
In the 2021 census, there were 30.4 million women and girls in England and Wales, and 29.2 million.
So the female sexual offending rate was 119/30.4 million or 3.9 per million and the male sexual offending rate was 11,660/29.2 million or 399 per million, which is almost the same as the numbers in the meme (the meme maker, who I assume was i/o @eyeslasho, might have been using a different table of column that I was unable to reconcile with my numbers at midnight while I was writing this post, but that is like a rounding error).
Tellingly, in New Zealand, Scotland and Queensland Australia, transwomen are similarly overrepresented in sexual offences.
Of course, the most prolific left winger in that thread had already proclaimed that "politicians" couldn't be trusted when what they said hurt the left wing agenda, so we know he was just trying to troll and piss people off with the common left wing of tactic of demanding a source, then dismissing it when it is inconvenient (all the while claiming other people have failed logic, lying that he checked out the real figures and they didn't match the meme and challenging others to look at the sources for themselves), but for everyone else who wants to know how the numbers above were derived, I hope this helps.
Related, previous work I did on a similar overrepresentation of trans people being rapists compared to the general population: Transgender offending vs victimisation.
