hanging/strangulation (9,164, 49%);
self-poisoning (4,098, 22%);
jumping/multiple injuries (2,423, 13%).
All three are equally available to men and women and anyone else.
In terms of rate, male suicide rate 17.2 per 100,000. Female suicide rate of 5.4 per 100,000
London has the lowest overall rate of just 7.3 per 100,000, 65% of the national rate. North East being highest at 14 per 100k.
The highest population group being Males aged 50-54 years, being 27.9 per 100,000
Wales is even worse, with Males aged 45-49 years being 32.3 per 100,000, and overall 21.6 (male) // 7.5 (female)
Generally the worse the economic opportunities, the higher the rate. Middle aged men are most at risk, men in general are at high risk, and guns have nothing to do with it
The sex difference in completed suicides is nearly universally 3-to-1 to 4-to-1.
My mental model is that men tend to be more extreme and less conservative than women (risk-taking is more prevalent), and this leads to more extreme approaches in how they try to kill themselves.
But it's been a while since I've read any of these statistics, and I have no special credentials. Just thinking about what we're observing.
Try again.
It's not the most plausible hypothesis. Men are more likely to own firearms than women are, therefore they're more likely to attempt suicide by firearms.
