“According to Anton J. L. van Hooff, hanging was the most common suicide method in primitive and pre-industrial societies.[7] A 2008 review of 56 countries based on World Health Organization mortality data found that hanging was the most common method in most of the countries,[8] accounting for 53 percent of the male suicides and 39 percent of the female suicides.[9] In England and Wales, hanging is the most commonly used method, and is particularly prevalent in the group of males aged 15–44, comprising almost half of the suicides in the group. It is the second most common method among women, behind poisoning. In 1981 hanging accounted for 23.5 percent of male suicides, and by 2001 the figure had risen to 44.2 percent.[3] The proportion of hangings as suicides in 2005 among women aged 15–34 was 47.2 percent, having risen from 5.7 percent in 1968.[10] In the United States it is the second most common method, behind firearms,[11] and is by far the most common method for those in psychiatric wards and hospitals.[12] Hanging accounts for a greater percentage of suicides among younger Americans than among older ones.[13] Differences exist among ethnic groups; research suggests that hanging is the most common method among Chinese and Japanese Americans.[14] Hanging is also a frequently used method for those in custody, in several countries.[2]”
