Suicide is rare under 14 years but thereafter increases with increasing age, with males predominating. The suicide rate for 15-19 year olds in England and Wales has increased since the nineteen fifties for both males and females, with a recent substantial rise in males. There has also been an increase in the small number of female suicides aged 10-14 years between 1941-50 and 1971-80. In younger age groups there is a higher proportion of undetermined deaths compared with officially recorded suicides, and this category has recently increased disproportionately in the young. The number of deaths by poisoning with solids or liquids recorded as suicide, accidental poisoning or undetermined poisoning has increased markedly in young people, and the relationship between the three groups might repay investigation.
14岁以下自杀情况罕见，但此后随年龄增长而上升，男性居多。自20世纪50年代以来，英格兰和威尔士15至19岁青少年的自杀率，无论男性还是女性都有所上升，近期男性自杀率大幅上升。在1941年至1950年与1971年至1980年期间，10至14岁女性自杀的少数案例也有所增加。与官方记录的自杀案例相比，较年轻年龄组中死因不明的死亡比例更高，且这一类别在年轻人中最近增加得不成比例。记录为自杀、意外中毒或中毒情况不明的固体或液体中毒死亡人数在年轻人中显著增加，这三组之间的关系可能值得研究。
