There is mixed evidence of a relation for suicide rates in the general population with urbanisation. A cross-national study of 76 countries was undertaken examining the a priori hypothesis that the relation of the general population suicide rates with urbanisation, using data from the World Health Organization and United Nations, would be curvilinear and follow an inverted U-shaped curve, with a quadratic pattern. The predicted curvilinear relation was not found. This may have been due to major methodological limitations in cross-national studies, so this hypothesised curvilinear relationship may be better examined in longitudinal studies over time in individual countries undergoing urbanisation.
关于一般人群自杀率与城市化之间的关系，证据不一。一项对76个国家的跨国研究进行了，该研究检验了一个先验假设，即利用世界卫生组织和联合国的数据，一般人群自杀率与城市化之间的关系将呈曲线状，并遵循倒U形曲线，呈二次模式。但未发现预测的曲线关系。这可能是由于跨国研究存在重大方法学局限性，因此这种假设的曲线关系可能在经历城市化的各个国家进行的长期纵向研究中得到更好的检验。
