@theorist I think your inquiry is reasonable, but, as I’m sure you know, the subject is both sensitive and complex.
The complexity comes from the fact that occurrences are both infrequent and have a tendency to cluster. Anything less than a 10 year measurement period is suspect. The frequency varies by age, gender, race and time. This makes it very hard to tell if prevention programs are working.
The prevailing opinion now appears to be that it is good to talk about it, whereas in the past people assumed talking about it increased the frequency. So, in the spirit of creating a dialog, here is the data I could find:
College students appear to to commit suicide at about half the rate of the age group within the general population. One theory is that this is due to the lack of access to firearms (which account for about half the suicides in the general population).
In terms of the size of the problem:
About 6% seriously consider suicide
About 1.5% attempt it (women attempt more often)
Less than 1% are successful (men have a higher rate)
Here is a summary of data.
