'There is no public consensus on what factors should determine where a transgender offender is housed, regardless of whether they are a transgender man or a woman. The most common answer was that there should be a specific wing or prison for transgender inmates, with a quarter (25%) of Britons choosing this. The next most frequent responses were that it should be based on the individual’s current physical characteristics (15-16%), their sex at birth (12-13%), or the gender they identify as now (11-12%). Another 9% say placement should be determined by a person’s legal gender.'
