The apertures of the chupa pots from the three Philippine locations: Dalupa (ApDl), Dangtalan (ApDg) and Paradijon (ApP).
potA multivariate data set with 343 observations on 2 variables: apertures and locations.
Archaeologists are concerned with the effect that increasing economic activity had on older civilizations. Economic growth and its related economic specialization led to the "standardization hypothesis", i.e. increased production of an item would lead to its becoming more uniform. Kvamme, Stark and Longacre (1996) focused on earthenware, chupa-pots from three Philippine communities that differ in the way they organize ceramic production. In Dangtalan, pottery is primarily made for household use; in Dalupa there is a non-market barter economy where potters exchange their works. In the village of Paradijon, near the Provincial capital, full-time pottery specialists sell their output to shopkeepers for sale to the general public.
