It's a fact that females are two to four times as likely as males to attempt suicide. Data showing this. And here's more data. And here's still more. Just as examples illustrating my point on that.
But let's get more specific to the group the OP is discussing: this is also true specifically among not just women overall, but also, and in a more pronounced way, among girls, including American girls.
And yes, the rate of depression is also much higher among American girls specifically than it is among their male counterparts (about 2.5 times as high, specifically), and is rising faster as well.
