When creating a Custom Faction, one of the sweet things you can do is select a starting minor population. This is a different species which starts living on your home planet and can lead to creating some pretty interesting combo's, such as selecting Euphorists (+4 Approval on Fertile) for your own population, and Niris (+3 Food on Fertile, +2 Food) as starting minor population, Giving your faction a pretty nice boost when your home planet is Fertile.

However, currently, the Starting Minor Population statistics are not displayed when hovering them in the "Available Traits" section of Creating a Custom Faction.

So here is a list of the Minor Populations available and their benefits, enjoy:
