That wiki article cites https://www.cdc.gov/ncipc/wisqars https://www.cdc.gov/ncipc/wisqars (which I guess is now https://wisqars.cdc.gov/ https://wisqars.cdc.gov/) and doesn't really show us how that number came about. But let's say you look at 2022 data for Fatal/NonFatal Injury Reports.[1] 49,476 suicide deaths with 14.85/100k crude rate and 14.25 age-adjusted rate. There is no 'suicide attempt' category that I can find for NonFatal. There's a self-harm category.[2] 544,992 self-harm non-fatal injuries with 163.52/100k crude rate and 172.91 age-adjusted rate. Sure, we could divide those out and reach roughly 1 in 11 to 1 in 12. But if you look at the definition for self-harm intent in the coding manual[3] you'll see that it's not just suicide -- it's all forms of self-harm including mutilation. So it's probably not an accurate number, even for a naive estimate. I would want a better source (surely someone somewhere has written a paper on this).
