So I've played Fallout 3 and new Vegas and I'm not sure if I missed it but my question is: Is every who we see throughout the Fallout games and I mean every single person you meet in the wasteland FROM A VAULT? Well I'm sure a lot of people survived the atomic blast by hiding in their own shelter or building or cave and repopulated the world but I wondering if like 50% or 90% of the world population in Fallout is from a Vault??
