An oft repeated statistic is that 45% of transgender people attempt
suicide at some time in their lives. A simple spread sheet calculation
shows that this probably can’t be the case given the observed increase
in the number of transgender people. Something else must have been
going on with the particular study that is often cited (and misquoted)
for that statistic. If that statistic is generalize-able to the whole
transgender population then over a 50 year period the transgender
population shrinks by half.
