Yes. The Economist is cherry picking data from one place, in one narrow period of time. All of the other studies (that you keep ignoring) cover much larger samples of people, over longer periods of time.

Also, "number of successful suicides" is an extreme, myopic metric for mental health. Ignoring all of the upstream signs of decreased mental well-being, and focusing only on successful suicides, is like measuring societal well-being exclusively by homicide rate.

"Sure, people are depressed, anxious, isolated and panicked, have increased suicidal ideation, and are seeking therapy in greater numbers than ever before...but they're not successfully killing themselves! All is well!"
