Umm, that chart is 10 years out of date - it ends in 2015; the beginning of the social media era.
The current teen suicide rate is ~62 / 100K, which is just about double (or triple!) the last value in that chart. And is also an anomaly over the last 40 years.
I stand corrected on the current stats. I went with what the CDC had on a google search. It's aggravating that most sources don't show the entire picture.
Here's a chart showing that this trend is mostly in the mountain states and Native Americans are the largest demographic affected by this trend by nearly triple. Both these stats disprove the theory that social media has much of an impact on teen suicide across the entire nation, otherwise why wouldn't states like California and Florida have a higher rate? Residents of those states obviously use social media too.
The social media area had been in full swing for 10 years by 2015. Facebook was established in 2004 and blew up by 2006. Twitter blew up a few years later.
The narrative that social media is the cause in the rise of teen suicide across the country is simply false. Native Americans in mountain states are bearing the brunt of it and causing the national average to spike. Instead of "tilting" to social media, we should try to understand why Native American teens are having such a difficult time and solve that problem. That doesn't draw headlines though, does it?
