The most important sector was manufacturing, where profits nearly doubled from 1986 to 1989 to peak at 3million.
Could I use “which” instead of “where” here? If not, why?
No, but you can use the phrase "in which" to replace "where" in that sentence. The reason is that "where" is a relative pronoun of place or location (the "place" being the sector in which profits nearly doubled) whereas the single word relative pronoun "which" is not.
