Quipus and tribute
As a tribute from its subjects, the Inka State demanded not money or goods, but labor. The organization of this state labor service, or mit’a, was based on the coordination of work shifts performed by groups of tribute payers who were organized in decimal hierarchical work groups. At a local level, groups of 10 tribute-paying households were joined together to form basic work groups for state projects. Five groups of 10 tribute payers were combined to produce a unit of 50 households. Throughout the administrative hierarchy, the basic organizational principles were the pairing of five-part decimal work units – that is, 50, 500, and 5,000 – to produce, respectively, work groups of 100 (pachaca), 1,000 (waranqa), and 10,000 (huno) families or households.
The Inka administrative systems were organized in this hierarchical fashion to supervise and record the work of the state laborers. At every level of supervision and coordination, the administrative officials maintained up-to-date quipu records of the tribute payers in their charge. Thus, there were small and large quipus, each reflecting the size of its corresponding state labor group .
Owing to its structure and types of recording units, the quipu was ideally suited to registering information in a decimal hierarchical format.
