No fully nomadic human populations currently inhabit the Sonoran Desert. Historically, however, several Indigenous groups practiced semi-nomadic seasonal rounds within this 100,000-square-mile region spanning Arizona, California, and Mexico:
These groups occupied defined territories with recognized boundaries, not unlimited migration. Their movements followed resource cycles—saguaro fruit, mesquite beans, game, water—within ancestral lands.
Today, these nations live in established communities (reservations, ejidos, municipalities), maintaining cultural ties to the desert while engaging in modern economies. The romantic "desert nomad" image reflects outsider projection more than historical reality.
