This reminds me of the Foxconn suicides. Lots of press made it sound like a major problem, but the actual rate was lower than both China and US averages.
The averages include non-functioning alcoholics, drug addicts, retirees with no money to live on, who don't want to be a burden on their children, chronic gamblers, people in serious debt, people who are terminally ill, people who are too depressed to hold down a job, veterans with PTSD...
In short, not the same demographics as people holding down 'decent' jobs for the area.
