Visible Wealth in Past Societies: A Case Study of Domestic Architecture from the Hawaiian Islands

Domestic architecture is increasingly revisited as a source of data about wealth inequality in the distant past via the Gini coefficient, a statistical tool often used in economics to compare income inequality. Many areas—including South America, Africa, South Asia and Oceania—remain under-sampled, making it difficult to develop a more complete picture of ancient political economies. In this paper we present a first look at this measure in the Hawaiian Islands. These data show that during the period prior to contact with Europeans inequality was extremely high, most similar to autocratic archaic states. We also found geographic patterning that may ultimately be linked to dryland (non-irrigated) farming. On islands reliant on dryland farming (Mau‘i, Hawai‘i), we find distinctively less inequality than elsewhere, or larger house sizes. We hypothesize these may have been innovations in how wealth was made visible to create and maintain cooperation in places where more labour would have been required to grow surplus. More research is necessary to test this hypothesis, investigate alternative interpretations, and to put these findings in larger regional context within Polynesia.
