That's a narrow time slice and age range. For example, suicide rates by teens fell between 1995 and 2000 (see table below). That certainly was not from decreased acceptance of dysphoria. Further, the states that are the most trans-friendly have the lowest rates of suicide.The level of reporting dysphoria you've admitted to has risen along with the level of hospitals reporting admissions for treating the injuries of kids who deliberately harmed themselves, and the level of reporting deaths due to teen suicide. I do hope it is a talking point because we should be talking about this.

Your correlation does not hold up over a longer period of time, or comparing state-by-state.
