Population of Himarë in Spille, Potam and Fshat?

Himarë is a curious town in Albania with an interesting history. Are there any figures on the current population of Himarë fshat (village/old town around the Himarë castle), Spille and Potam neighbourhoods?

Are there a majority of Greek speaking people in all of these parts of Himarë? Or is it mixed with Albanian-speaking people?
