I have a paragraph starting with the below sentence. "it" is not referring to any specific noun. Is there any problem with that?

It has been estimated that health care costs accounted for 11.6% of Canada’s GDP in 2019, the majority of which were spent in hospitals.

  • Does this answer your question? What is "it" in the following sentence: It is clear that Bob likes doughnuts This is the dummy 'it' associated with extraposition. In John Lawler's answer to the duplicate question, he gives a link to an article stating that there are various dummy it's (non-referential) as well as the usual referential version. The French conveniently use a different word ('ce' rather than 'il' etc). Aug 17 '20 at 13:59
  • This is one example where the non-extraposed equivalent would not be possible.
