Demographics
Prior to the arrival of the Dutch colonists, Taiwan was almost exclusively populated by Taiwanese aborigines; Austronesian peoples who lived in a hunter-gatherer society while also practicing swidden agriculture. It is difficult to arrive at an estimate of the numbers of these native Formosans when the Dutch arrived, as there was no island-wide authority in a position to count the population, while the aborigines themselves did not keep written records. Even at the extent of greatest Dutch control in the 1650s there were still large regions of the island outside the pale of Dutch authority, meaning that any statistics given necessarily relate only to the area of Dutch suzerainty.
