As PPs are saying, the problem is we just don't know enough about these figures. As Moobaa says, it may be basically a list of phone calls made to police, in which case it doesn't tell us anything about hate crimes against trans identified people. Or perhaps it's a 100 per cent accurate record of actual hate crimes. The problem is we don't know.
The force where I live, Avon and Somerset, has since 2017 recorded a strand of 'gender/misogyny' hate. I wrote to them to ask about this and was told 'The overwhelming majority of these cases are described as Misogynistic in their motivation.' Booooring right? God forbid we have something just about women and the hate we face.
Their ideas about what constitutes a hate crime motivated by transphobia are alarming: 'If a person identifies as a Trans woman then it is Transphobic to deliberately refer to them with male pronouns. Depending on the circumstances and location this could be a Public Order Offence. They are protected by the Equality Act 2010 and this could be reported as a Hate motivated incident or Offence according to current police policy. Hate Speech in other contexts eg On Line abuse or offensive literature can also be an offence.'
Worrying that the senior police officer cited EA2010 which is not the law covering hate crime.
Here are the stats for 'hate incidents recorded' pre 2017 (so pre 'gender/misogyny) - 67% racially motivated. 1% trans. The trans figure is similar to population size while the racial figure is much higher than the BAME % of population.

Avon and Somerset record by gender not sex, and they do not disaggregate incidents against lesbians from incidents against gay men.
