It looks like the average rate is 97 per million per year in China. Foxconn employs around 350K in China (other posters are claiming 1M, but I took the most conservative figure I found).
With 350K employees, you’d expect about 34 suicides per year if their rate was at the national average. At 3 a month, yeah, I’d put up nets as well.
While I’m sure the reporting doesn’t tag every worker who happens to commit suicide as a Foxconn suicide, I don’t see evidence that the Foxconn suicide rate is higher than the national average and sibling comments and Wikipedia (sourcing ABC News and the Economist) are claiming it’s lower.
