2.4% of all respondents (107850 people) said they'd had conversion therapy.
That's over 2,000 people.
Of the 14,260 'trans' respondents, 4.3% said they'd had conversion therapy. (Or 'reparative' therapy).
That's around 600 people.
And it's important to note that people identifying as 'trans' might have been reporting LGB conversion therapy, not therapy to change their 'gender identity'. In that context, this note from the government assessment of the evidence seems kind of crucial:
'...in addition to the survey not being a representative sample, it did not distinguish between transgender respondents who had conversion therapy to change their sexual orientation and respondents who had it to change their gender identity.'
So although the survey split respondents by sexual orientation and by 'trans' identity, it's impossible to know how many people who identify as 'trans' received conversion therapy for sexual orientation.
The rest of the assessment leans almost entirely on data from the US and/or other countries. Very different politically, religiously, socially, culturally.
