Population score is based on the amount of base food on the map (not counting improvements like farms, plantations, windmills) and how much population you get relative to that base amount. So if you want a big pop score, get lots of cities with food improvable tiles (and biology) and farm/windmill everything, get rid of all your cottages before growing pop to max (don't worry about unhappiness) before winnning.
