I assume you're alluding to Suicide contagion. Yes, in fact the more suicides reported the greater the lagging residual contagion cluster effect results. If everyone's killing themselves these days, said the media*, more people would be inclined to go through with it and suicide would be a common day reported Act.
Suicide is the second leading cause of death for ages under 34. But I would be highly skeptical of that and call it the first leading cause of death. Suicideologists know this very well in that the statistics are heavily underreported. Suicide needs some proof of intent, without any proof of intent that the person intended on killing themselves then the cause of death can't be confirmed as a suicide but an accident. How many millions push and plunge the needle over the edge or drive off the ledge knowingly to their end? What about missing persons who just disappear in the woods never found or go overboard? That would be an extra few million.
And then there is the topic of the ratio between attempts and successful deaths by suicide. About 54% of attempts are signaling and these are classified as impulsive acts which are self-injurious but lacking any planning or deficient comprehension or calculation of comprehension or calculation of lethality. The majority of these are "signaling" cries for help, and very few actually want to die. The cohort that really wants to die and has the 95% success rate is that group which has a very calculated, planned and redundant (failsafe dual / triple stacked methods) in a very high-lethal plan with deterrents to rescue (by DNR or remote location, or both) and are intent on executing it without sidelining, I usually this will come together during a flashpoint of events and when all of the pieces of the plan are in place, the ones that have truly given up on all hope and given up on life. The majority of attempts are not as heavily planned for and are rather haphazard, resulting in jury without death, sometimes substantially life-changing. Which is why you shouldn't attempt unless you've been firm on CTBing for long and have a plan. As they say failing to plan, is planning to fail.
*Which is what the media does not say and is careful reporting on in conformity with ethical guidelines. But just imagine the power the media wields - if suicide became mainstream then most of us would have already been enticed enough to attempt it by the bandwagon effect.
