The quick search I just made for suicide rate per capita shows the rate in Singapore is kinda average.
The author said that it is rising rapidly, not that it is currently high.
I am the author of this article. The wikipedia article on suicide rates (which I am assuming you found via google) uses data from 2009 as its source. The article I wrote uses data from 2011 (which is the most recently available.) More details here: http://www.lifelisted.com/blog/happens-everything-goes-right...
