In a country with 2 billion people is that a high rate compared to the rate of the rest of the world?
Since they were writing an article about the subject, they decided to include that information.
The World Health organization put together a table to show the suicide rates per 100,000 by country and gender, using the most recent information available to them in 2011. There were only two other countries listed with higher female suicide rates than China: Korea and Sri Lanka. There were forty-seven countries listed with higher male suicide rates than China. Among these were many European countries, the United States, and Canada.
Don't bother reading articles though. It interferes with the fun of asking inane questions.
