This study investigates the under-reporting of suicide with particular
reference to differences between sex and age groups and the various m
odes of suicide. The study was performed retrospectively using the fil
es of H M Coroner for South Yorkshire (West) over the years 1985 to 19
91. There were 536 deaths judged on the balance of probability to be s
uicidal in nature. Only 60 per cent of these deaths received a suicide
verdict and would therefore register in official suicide statistics.
A significantly smaller proportion of females (51.7 per cent) received
a suicide verdict than males (64.5 per cent). Of the young females (<
45) 61.7 per cent were given a suicide verdict compared to 46.6 per ce
nt of older females (45+). These differences are explained by differen
t preferences for mode of suicide, in particular for poisoning using s
olids or liquids. Only 40 per cent of cases within this category recei
ved a suicide verdict. Drowning showed an even smaller percentage (24
per cent). Self-immolation (42 per cent) and jumping from a height (51
per cent) were also under-represented. Of these, self-poisoning, drow
ning and jumping from a height were relatively popular among females.
In contrast, common causes of death favoured predominantly by males -
hanging and carbon monoxide poisoning - received a high percentage of
suicide verdicts (81 per cent and 90 per cent). Thus official suicide
statistics produce a distorted view of the suicide population with rel
ative underreporting of females, particularly older females, and marke
d under-reporting of some causes of death, notably poisoning using sol
ids or liquids, drowning, self-immolation and jumping from a height.
