That was my first thought too but the total is globally, so it seems like quite a small number even when considering trans people account for ~1.4% of the world population which would be about 113,036,000 people.
Man that's fucked up.
"Good news! Proportionally, less trans people were murdered!"
That's why I said accounting for demographics. There are proportionaly more trans people in richer countries where murders are also lower. But I don't know how one would do that full demographic comparison.
So if you dig into the actual data, they point out that this is probably far from the actual number of murders, since it is only reported, and not all jurisdictions participate. One concerning thing though that I saw was that 94% of all the reported murders were of trans women.
And almost half were sex workers. I would bet that the real number is much greater, considering the numerous countries that wouldn't be recording the person as being trans. Due to the stigma associated, I'm guessing that it's more likely sex workers will be designated as 'trans' rather than general population, due to the conservative nature of many countries.
