This has been a big talking point on HN since all this started, but the data we have so far shows that suicide rates did not increase.

Suicide isn’t something that necessarily occurs right after the events in question. After you destabilize someone’s business/career/income it can take a long time for the ripple effects(ex: divorce due to money trouble, the addiction you acquired to cope finally getting out of hand, …) to play out and for someone who’s been enduring a bad situation to eventually succumb to despair. We’ve also deliberately delayed, but not prevented many of the ill effects, for example with the eviction moratorium. It may not be long before all those people with back rent and back electric bills are out on the street. In my estimation we won’t know the effect of this pandemic on suicide rates for a few more years.

The linked guide mentions this. The fact remains: there is no evidence, currently, to suggest increased suicide, and specifically in regards to "lockdowns". You could argue it's the coming months, and "recovery", that make or break this, not the response when the virus was actively raging.

In 2020 California had around 4500 suicides and in 2019 Florida had around 3500 suicides. Florida experienced a 10% drop in suicides for 2020 and had around 35,000 Covid deaths. California had around 62,000 Covid deaths. If you are going to argue against the efficacy of lockdowns then your focus ought not be about number of suicides. Do you have a more relevant argument?
