Most of those are warehouse employees whose suicides might not make Bloomberg. And people who die quietly at home (which I've seen a few times in my career) likely don't either.

I don't think it is correct to get the expected value of suicides using the national average. College-educated people employed at a high paying job living in Seattle may be much less likely to kill themselves. (Making some assumptions about the person who attempted suicide).
