I recently answered a question on a Skeptics Stack Exchange where I said this:
Scientists from Harvard University and other countries such as Cyprus and Germany measured the most detailed estimates yet of the toll of air pollution, in a quest to find the cause. The study found that outdoor air pollution is killing 3.3 million people a year worldwide, that is divided as such:
- China: 1,400,000 deaths/year.
- India: 645,000 deaths/year.
- European Union: 180,000 deaths/year.
- Pakistan: 110,000 deaths/year.
An editor later, converted "as such" to "as follows" and mentioned "grammar" as the edit cause. So, I asked my friend who is doing his PhD in linguistics what is the difference between them; but he didn't know.
My questions are: Was the use of "as such" grammatically incorrect in this paragraph? When should I use "as such" vs. "as follows"?
