Before everyone jumps in with their favorite ad-hoc reason, take a look at the graph first. The headline is technically true, but barely. For the 45-64 age group, the suicide rate is barely different than it was in 2012 and 2018, and about the same as it was in 1985 (24 vs 22-23 per 100k.) Seems like all age groups have held steady (10-24 25-44 and 75+) or trended up a bit (45-64 and 64-75) since the early 2000's, after dipping from the 1980s.
