Suicide is a violent crime, the killing of a human being.
Now, if we believe Wikipedia, then around 90% of homicides in the US will be committed by males. It seems reasonable that the male-female ratio should be about the same in the UK.
Then a 0.8 ratio of male to female suicides could be accounted for by the increased male homicide rate alone.
Perhaps men access certain modes of physical violence (guns?) more easily, but how are the psychological states of murder and suicide related at all? I understand amok/revenge murder-suicides but most suicides aren't that. "Violent crime" doesn't seem like a useful way to carve up reality here.
