Fewer , the comparative form of ~ , is correctly used with words denoting people or countable things, while less is used with mass nouns, denoting things which cannot be counted. In addition, less is normally used with numbers and expressions of measurement or time. The use of less with a count noun ( less people ) is incorrect in standard English.
