The number of transgender inmates housed in Texas' prison system is at an all-time high.

According to The Dallas Morning News, 333 Texas inmates identify as transgender, a staggering nearly fivefold increase in the last 24 months.

As part of the Prison Rape Elimination Act, state prison and jail officials are required to consider a person's gender identity when deciding on housing. Transgender inmates are more likely to be the targets of violence and rape than the general prison population.

In early 2014, the Texas Department of Criminal Justice began a campaign to identify transgender inmates. The following year, the department said it would allow inmates diagnosed with gender dysphoria to begin hormone treatment while in prison. Previously, inmates could only continue treatments while in prison. That is, they had to be diagnosed before entering the system.

However, only 32 inmates are currently receiving hormone therapy.
