I heard this sentence from a speech:
The number of people and even the percentage of the population both living in extreme poverty has really gone down over the past two centuries.
(Yalecourses, "Lecture 4: Fusing Capitalist Economics with Communist Politics: China and Vietnam," published on Youtube)
But I can't understand this part well. In my opinion, "both" is a pronoun which refers to the subject "number... and the percentage...", while "living in extreme poverty" modifies "people", but:
- Why is "living in extreme poverty" after "both"?
- Why using "has" but not "have" when the subject is refered to by "both"?
The following version will make me feel better:
The number of people living in extreme poverty and even the percentage of the population both have really gone down over the past two centuries.
