What Inca decimal unit represented one thousand households?

The Inca decimal unit representing one thousand households was the huaranga. It belonged to a hierarchical system that organized households for administration, labor obligations, taxation, and military service.

The decimal structure grouped households into progressively larger units. A pachaka represented roughly one hundred households, while a huaranga represented roughly one thousand. Larger groupings could combine several huarangas, allowing officials to organize a vast and diverse empire through local administrators and carefully defined responsibilities.

The system was administrative rather than a simple census in the modern sense. Household numbers could vary, and the practical organization of communities differed by region. The Incas relied on local leaders to supervise people and obligations, while khipu cords helped administrators record numerical information such as population, goods, and labor.

An ayllu was a kin-based community and landholding group, not specifically a thousand-household unit. Pachaka refers to the hundred-level grouping. Hunu was associated with a much larger grouping, commonly described as ten thousand households, so it is not the best answer here.
