Ok, I went ahead and did some (admittedly) cursory reading so I could ”do the math”. You didn’t give enough information.
[One thing that caught my eye while reading is that the jump in suicide rates are seen in unemployed people in a longer term timetable, like 3 to 5 years, so an immediate jump is improbable at best. This would, of course, bring into the discussion a “how long will this economic impact last” factor. I am sure that we have differing opinions on that, so to keep ”the math” simple I will stipulate that the impact is felt immediately rather than go down the other rabbit hole. In other words, the increase in suicide rate among unemployed will be considered to be immediate rather than incrementally applied.]
Suicide rates in the U.S. have been creeping up over the years - as of a couple of years ago was around 14 per 100,000 (was closer to 10 per hundred-K a decade prior). I’ll use 15/100,000 as baseline. I’ll use a doubling of the suicide rate for the unemployed. For round numbers, I’ll use 50,000,000 additional unemployed workers.
Doubling the suicide rate means that there would be an additional 15/100,000 amongst the unemployed.
(15/100,000) * 50,000,000 = 7,500 additional deaths per year.
How did I do?
