https://www.apa.org/monitor/2019/03/trends-suicide > The suicide rate increased 33 percent from 1999 through 2017, from 10.5 to 14 suicides per 100,000 people (NCHS Data Brief No. 330, November 2018). Rates have increased more sharply since 2006. Suicide ranks as the fourth leading cause of death for people ages 35 to 54, and the second for 10- to 34-year-olds. It remains the 10th leading cause of death overall. >But…
Facebook is global, the fact the suicide rate only grew in the US and not worldwide is a point in its favor. Not to mention the increase in suicide rate is higher for older generations who use social media less, according to the data.
Not necessarily. To oversimplify things to make a point, suicide may have two ingredients: Facebook and something else. The US has an increased rate because has both (Facebook and the other ingredient), while the other places don't because they only have one ingredient (Facebook) and are missing the other. It's not a point in Facebook's favor if it is one of many ingredients in a recipe for suicide, and Facebook may be the easiest ingredient to eliminate.
And that's totally plausable. The US has many unique cultural factors (e.g. highest rating of individualism of any country).
