> But there’s also something weird with 1999 Are you looking at the year the death happened, or the year it was registered? We think there's a "cohort effect" with suicide deaths. So, all people born in decade X have a higher rate of death by suicide, and we see this as they get older. Here's an example from England. https://twitter.com/ProfLAppleby/status/1161940914308300801?s=20 https://twitter.com/ProfLAppleby/status/1161940914308300801?... Here's CDC suggesting that may be a factor: https://www.cdc.gov/mmwr/preview/mmwrhtml/mm6217a1.htm?s_cid& https://www.cdc.gov/mmwr/preview/mmwrhtml/mm6217a1.htm?s_cid... > Possible contributing factors for the rise in suicide rates among middle-aged adults include the recent economic downturn (historically, suicide rates tend to correlate with business cycles, with higher rates observed during times of economic hardship) (6,7); a cohort effect, based on evidence that the "baby boomer" generation had unusually high suicide rates during their adolescent years (8); and a rise in intentional overdoses associated with the increase in availability of prescription opioids (1,2). Additional research is needed to understand the cause of the increase in age-adjusted suicide rates and why the extent of the increase varies across racial/ethnic populations.
