I'd say it's up - or it has been. In part because of the Japanacorps' mode of 'we failed, we must expiate our failure and loss of honor via seppuku', in part because RHat is right in the idea (that hopelessness is the trigger for suicide) and ... not necessarily right in the execution. Hopelessness has many causes.
Their overall personal situation improving? That's less a cause than you might believe. Sure, that's a thing, but you can get used to anything, and there are thousands living in the Barrens areas, getting by every day one way or another, with one reason or another to live until tomorrow. The most suicides there would come from the totally-devoted single wageslave that got turned out by the corporation (because it was no longer profitable to keep them), very early on in their post-corporate life - meaning within a week or so, just because of the shock. Possibly even before they leave the corporate premesis - they get their pink slip on Friday, go to their corporate apartment to pack up, and just kill themselves instead. That of course would lead to corporate 'mobility assistance' personnel packing their things FOR them and meeting them at the door out of the workplace, or just them having been escorted to the front gate, with all their stuff. "Here you go, good luck." Open a vein outside, not on corporate territory, where we're obliged to give a crap and a funeral.
Other concerns are more likely - not meeting a deadline, getting painted into a corner by rivals, that sort of thing. The manager is confronted with a meeting in which he knows he's going to get canned, so ... he takes the easy way out, and kills himself. Suicide-level despair tends to be more of an immediate-issue thing, not a long-term one. It might be the cherry on top of a thoroughly-baked 'your life is crap' cake, but it's the immediate pressure thing that's still most likely to break the camel's back.
