So someone will have to provide data showing an increase in suicides if they’re going to use that as an argument against the lockdown
"Dear everyone, please save me the trouble of spending five minutes with google, because I thought maybe that when a person was sacked and broke they'd be happy."
Okay.
"After the 2008 economic crisis, rates of suicide increased in the European and American countries studied, particularly in men and in countries with higher levels of job loss." - source 1
"prior to the onset of recession in 2007, suicide rates had been falling in Europe. Subsequently, this downward trend reversed, rising by 6.5% by 2009 and remaining elevated through 2011. This increase corresponds to an additional 7950 suicides above what would be expected on past trends between 2007 and 2010" - source 2
"Being unemployed was associated with a twofold to threefold increased relative risk of death by suicide, compared with being employed." - source 3
Oh and see figure 1 here - source 4
So your first source showed an excess suicide of ~5000 across all 54 countries studied. That’s an incredibly small number and you should know that the statistical significance in that finding is confounded by lack of multiple comparisons.
Also, “ Spearman’s correlation coefficients between suicide rate ratios in 2009 and percentage point changes in unemployment rates between 2007 and 2009 were 0.25 (P=0.075) in men and 0.10 (P=0.49) in women. In men, the correlation coefficient was 0.48 (P=0.016) in men countries with relatively low unemployment levels (<6.2%) before the crisis and 0.31 (P=0.13) in countries with high unemployment levels (≥6.2%) before the crisis.“ no statistical correlation there when comparing actual unemployment to actual suicides, except in men in select countries with low unemployment pre-recession. From their discussion: “ Further, our analysis of suicides in the USA suggested that unemployment only explained a small proportion of the variance in suicide rates. Consequently, there is still a large residual not explained by economic shocks.”
Study two was poorly done, showing correlation but not even attempting to show causation, and providing no statistics for their main result. They nevertheless again noted “ Despite large recessions, some countries experienced no change in suicides, whereas in others suicides rose in step with worsening economies.” And they discussed it may be preventable in subsequent paragraphs.
Source 3 was a study from 1991 in New Zealand and found “ In a multivariable model the association of socioeconomic factors with suicide reduced to the null. However, marital status and labour force status remained strong predictors of suicide death. Unemployment was also strongly associated with suicide death among 18–24 year old men. Sensitivity analyses suggested that confounding by mental illness might explain about half, but not all, of the association between unemployment and suicide.”
That’s a very specific portion of the population, unrelated to a recession and also their note about mental illness being a major factor is quite relevant. Again not irreversible.
From the abstract from source 4: “In addition, while the impact has generally become stronger over recent decades, it fell during the Great Recession although remained significant.” Wouldn’t it increase if tied directly to the recession? I can't comment further as I don't have access to this article.
The CDC provides this figure:
https://www.cdc.gov/nchs/images/databriefs/351-400/db362-fig1.pngThey note that suicide rates started increasing in 2006, before the recession started, in men (started increasing by 0.2-0.5 per 100,000 each year since then). For the total population it started in 1996 with no significant acceleration afterwards (increase of 0.2-0.4 per 100,000 each year), and for women 1999 with no significant acceleration (increase of -0.1 to 0.3 per 100,000 per year).
For men, suicide rates in 2007 for men 18.5 per 100,000 and in 2018 was 22.8 per 100,000.
For women, 4.0 per 100,000 and 6.2 per 100,000
Total 10.5 per 100,000 in 1999 and 14.2 per 100,000 in 2018.
These trends are thus seemingly related to pre-existing economic factors rather than the recession itself.
You are thus technically correct that there is weak evidence to suggest a small increase in deaths. But overall trends show no major difference. Also if we’re being utilitarian here, an excess 5k deaths would be 2 days worth from this epidemic. Please explain how this bolsters the argument of re-opening the economy without proper infection containment measures in place (not sure if that's your argument, sorry, it's hard to keep track of everyone).
