Across the Southwest the advent of agriculture created social pressures as populations became less mobile and more densely packed. This resulted in the movement from subterranean pithouses to above ground multi-roomed pueblos. Archaeologists try to determine the causes for the transition, ranging from thermal efficiency to cosmological worldview. The more convincing explanations incorporate complex social interactions which impact architecture. These explanations of the social forces depend on rich datasets available in the US Southwest, while in Chihuahua, Mexico archaeologists are just starting to ask these questions. The majority of work has been in central Chihuahua on the pueblos of the polity of Casas Grandes (AD 1200-1350). Proyecto Arqueologico Chihuahua (PAC) provides a recent sample of sixteen pithouses from the southern zone of the Chihuahua culture dating to the Viejo period (AD 800-1200). These demonstrate the variability in ways ancient populations addressed the social pressures exacerbated by agricultural lifestyles.
