Unfortunately, no. There seems to be a lack of general population-based longitudinal studies on suicide and suicidal ideation. Most studies take place in the US or Europe, and almost all seem to be focused on particular subgroups like teenagers and young adults; combat veterans; or homeless people. This makes some sense, because one would expect people in these groups to have a higher risk of suicide than the general population. And, indeed, it is true, at least for teenagers and combat veterans; I'm not sure about homeless people. Maybe someone more familiar with this area knows of something, but I haven't seen it.
