 The Urarina are a semi-mobile hunting and horticultural society whose population is estimated to be around 2,000.Urarina settlements are composed of multiple longhouse groups, located on high ground ("restingas") or embankments along the flood-free margins of the Chambira Basin's many rivers and streams.The embankments are bounded by low-lying territories ("tahuampa " and "bajiales") that are susceptible to flooding during the annual rainy season (roughly November–May).
