You mean visual selected region?

Something like this, perhaps?
:'<,'>s/\<\%V\w\+\>\@=\%V\>/\=setreg('a', @a+1)/gn

This stores the count of all words within the visual selected region and
stores it in the 'a' register. The 'a' register should be initialized to
a number, that will be added up.

Best,
Christian
