North American Indians who traditionally lived along the Gila and Salt rivers in Arizona, in what was the core area of the prehistoric Hohokam culture. The Pima speak a Uto-Aztecan language and are usually considered to be the descendants of the Hohokam. Like their presumed ancestors, the Pima were traditionally sedentary farmers living in one-room houses and utilizing the rivers for irrigation. Some hunting and gathering were done to supplement the diet, and in drought years, which occurred on the average of one year in five, crop failure made hunting and gathering the sole mode of subsistence. During these dry years jackrabbits and mesquite beans became the group's dietary staples.
