'A small proportion of people'?

[Mehrgan]

Hi there,

Is there any limitation when using expressions such as 'a proportion of' in terms of the noun being countable or not?

I was wondering if expressions we use to express quantities (dozens of, a proportion of) are used carrying any positive or negative sense.
