Nick Land provides the 1928 suicide rate among kids, almost by accident.
A quick google gets me 2006.
Unfortunately the numbers aren't directly comparable. But, some quick estimates from the available data.
10-14: < 0.5 to ~1.5 per 100k
15-19: ~4 to 7 per 100k.
Slightly more dudes than chicks in this cohort used to kill themselves. Now, it's twice as often in 10-14 and four times as often in 15-19, matching the 1928 adult ratio.
This is not 'fallen by 20%'
So, err, even worse than I thought. Once again, the graph is cut off at a very convenient time. Or perhaps magic. The stats I stumble upon first happen to support my hypothesis - Google/Nick Land can psychically know my thoughts, as well as Alexander's - and therefore the stats Alexander stumbles upon first support his hypothesis too. Very nice of magic, don't you agree? Neighbourly. I thought I would have to skip checking suicide, and then the stats fall right into my lap.
This is even discounting the fact we don't want suicides, we want suicides-that-would-have-successfully-completed-against-1928-trauma-surgeons-and-ambulances, 2006. This is even discounting the fact that we know governments fudge the hell out of their numbers.
I also noticed a double bind. Either murder rates should be going up and are being kept down by trauma advances, OR murder rates should be going down, but stagnation in trauma medicine is holding them steady. Either way, the progressive has to play god of the gaps...assuming they can even think in straight lines long enough to notice there's a problem.
I found the opening sentences of the 1928 report a huge relief. It would appear it was written by an adult. With, like, perspective and stuff. I still wouldn't call the rate large, it's just that wealth should make it go down, not up - the trend is worrying.
Well, would be worrying, were the national rate any of my business. I'm only in this for the epistemology.
