For native American populations, standard estimates 50 years ago, and common estimates among experts 20 years ago, were for a few million. Now consensus is 10M-100M probably closer to 40M Pretty much ALL ancient world populations seem to have been traditionally underestimated by at least a factor of 2, leading to serious uncertainty as to whether total world population was ANY higher in 1650 than in 200. Some nomads subsist by raiding, others largely by herding sheep, horses, or cattle. In either case they are heavily occupied with defending their herds from other nomads, making them very martial in focus, but somewhat less so than knights are. Hunter Gatherers are also often specialized professional warriors to a significant extent, especially where nature is particularly bounteous as on many tropical islands. They usually do some fishing, nomads some animal husbandry.
