The suicide rates in England and Wales and Scotland converged during the late 1960s, and from 1970 were higher in Scotland. The convergence occurred because of differences in the falls in rates of those aged over 45 years and not because of differences in frequency and decline of coal gas suicide. Male suicide increased more rapidly in Scotland during the 1970s. In England and Wales overall female suicide rates fell during 1958-76 whereas in Scotland there was no clear trend. Suicide by car exhaust increased similarly in both countries, but that by hanging and drug poisoning increased more rapidly in Scotland.
20世纪60年代末,英格兰、威尔士和苏格兰的自杀率趋于一致,自1970年起,苏格兰的自杀率更高。这种趋同现象的出现是因为45岁以上人群自杀率下降幅度存在差异,而非煤气自杀的频率和下降情况有所不同。20世纪70年代,苏格兰男性自杀率上升得更快。1958年至1976年间,英格兰和威尔士的女性总体自杀率下降,而苏格兰则没有明显趋势。两国汽车尾气自杀率的上升情况相似,但苏格兰的上吊和药物中毒自杀率上升得更快。
