Suicide ideation is significantly more prevalent among women than men in both developed (2.2% vs. 1.7%, χ21= 12.5, p < .001) and developing (2.4% vs. 1.6%, χ21= 25.1, p < .001) countries. Suicide plans are significantly more common among women than men in developing (0.8% vs. 0.6%, χ21= 7.0, p = .008), but not developed, countries. Gender differences in the prevalence of attempts are not significant in either developed or developing countries. Overall, few socio-demographics variables were associated with suicide attempts among ideators. Specifically, in developed countries, younger age (i.e., <50 years-old) predicted unplanned attempts among ideators and unemployment predicted planned attempts. In developing countries, being a student predicted unplanned attempts and unemployment again predicted planned attempts. The bivariate ORs of these significant predictors were in the range 2.4–9.4.
