The projection of increased suicide in that study is based primarily on unemployment rate, but unemployment in 2020 is considerably different from unemployment in 2018 (the year they used as a baseline) due to unusual federal benefits that left as many as 68% earning more while unemployed than they did while working[0]. Actual suicide rates do to seem yet to be climbing as predicted, although it will take some time to see what the actual deleterious events turn out to be.
