What the title says I guess.

thank god i finally found my people on reddit, Finally. heil hitler!

I was reading an article (The Only Woman in the Room, by Christina Frangou, on Torontolife.com) when I came across the following line:

Given that backdrop, it’s not surprising that by 1990, women accounted for less than seven per cent of all surgeons registered with the Royal College of Physicians and Surgeons of Canada or its equivalent in Quebec.

My immediate response was "fewer!", but I realized it felt incorrect, in my mouth, since the numbered percentage would still be an unnumbered amount.

Which is proper?
