Indigenous peoples live in all South American countries. However, the share of the total population differs greatly per country (see source 1). The causes of these divergent percentages are many. In Uruguay, for example, only a few thousand people lived before the arrival of the Europeans. Due to European diseases and attacks by European settlers, hardly any Amerindians remained. In other countries, many indigenous populations were spared precisely because they lived in remote areas. Examples are the Quichua and the Aymara in Bolivia and Peru, who lived in the inhospitable Andes region.
