Int. J. Environ. Res. Public Health 2012, 9 762 was considered out of the scope of this article to investigate reasons for differences between various sources and possibly also misleading to present different sets of data for the same time periods. Even so, two datasets were involved in the analysis. The first was prepared by the WHO for 2008 to cover all causes of death and maximise inclusion of countries. Data were estimated according to a similar methodology building on population and all-cause mortality estimates, which was used to get 2002 and 2004 estimates and is described at [9]. The WHO member countries are grouped into six geographic regions: Africa, Americas, Eastern Mediterranean, Europe (including Russia), South-East Asia (including India), and Western Pacific (including China, Japan). Absolute numbers were available in the WHO database. Proportions of suicides among all injury deaths and suicide rates of different age-groups were computed as well as the male-female rate ratios. The second dataset was collected by the WHO from individual countries into the WHO Mortality Database to maximise precision of actually measured suicide mortality data and try to achieve comparability across countries. An overview of latest available data is presented at [10]. Data by individual countries are presented with 5-year time-intervals starting from 1950 at [11]. The WHO data about gender-specific suicide rates and total numbers, which were available country- by-country, were compiled into an overall table where countries were ranked according to the latest total suicide rate. Male-female suicide rate ratios were computed. Trend analysis was conducted for all countries and the most characteristic development patterns among those with the highest suicide rates over the past six decades were chosen to be presented in Figure 1—two countries from Central Europe, two from North Europe, two from the former Soviet Union, and two from Asia.
