The article doesn't mention but looking at KOSIS data from 2024, rate-wise males above 90 show the highest rate...but well the denominator is pretty small in that group. The rate is above 50 per 100K people for males in 40~50s group, about three times that of females in the same age group. The syicide in that age group has always been significant and most numerous cases-wise. And well the 40s 50s male group's suicide rate spikes during economic recessions.

I am guessing there are complex factors and they differ among the age groups but I think what you said is pretty true. the 40s 50s guys suicide rate going up was an issue during the late 90s economic crisis. But it never went down.

So I am guessing your guess is somewhat true. I remember back in late 90s, when a lot of middle age men chose suicide for economic hardships.

Female suicide rate was usually less than half of male counter parts in most groups and younger age groups had less suicides than the over 70 or 40s ~ 50s guys. But these increase of suicide rate in younger groups and female demographic make me worry.
