> It's simple maths. In the worst year for suicides, Foxconn had 14 deaths out of 930,000 workers. Divide one by the other and you get a remarkably low suicide rate by any standard.
You need to take it one step further; you should compare it to the suicide rate of healthy, employed young adults. If (for example) the suicide rate is higher than employed adults, but comparable to unemployed, it would show a serious problem at the factory.
In many industrialized countries suicide rates are not spread equally across all demographic groups.
