This is the most plausible hypothesis, judging revealed preferences by the outcomes.
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.
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 also may be down to what was available to them at the time. There’s a famous case study where a lot of women in the UK were dying by putting their heads in the oven and gassing themselves in the 1950s. The UK government changed the formulation of gas that was being piped to homes and the suicides stopped. If those women really were dead-set on suicide, they would have just chosen a different method.
What people who’ve never had extreme depression might not realize is that in those low moments it feels like you will always feel this way and it will never ever change. Then you wait an hour or so and the feeling passes. So a person may not feel suicidal 24 hours a day, only at specific moments. But in those low moments, the chances of suicide dramatically increase and as the UK case shows, accessibility to quick suicide methods makes a big difference.
