If you're on the outer rim (as when looking down on the galactic map) then the proportion of non-scoopable stars reduces the closer you get to the edge. It could actually be considered a defining characteristic of it - if you're finding more than one non-scoopable in every few hundred stars then you're not there yet
. The one exception to this is that you will occasionally come across pockets of brown dwarfs, but these are small (a few tens of LYs across) and they still contain enough scoopables amongst them.
It's different if you are going to the limits above or below the galactic plane where a lot of the stars are T-Tauri.
