Patterns of Indian Depopulation in Early Colonial Ecuador

Newson's regional reconstruction: 88% and 62–64% declines by ~1700, by mixed mechanisms

what the source states

Table 1: Napo-Aguarico 49,000–51,000 → 6,000 circa 1700 (87.8–88.2% decline, depopulation ratio 8.3:1); Mainas 83,000–102,000 → 30,180–38,490 (62.3–63.6%). "Epidemics, enslaving raids, and missionization were also the major causes of Indian depopulation in the gobernación of Mainas… excessive demands for service provoked widespread unrest that culminated in a major revolt in 1635." Also: "most opted to flee from exposed locations along the… major rivers."

• Upper-Amazon provinces with mission records; extension to the middle/lower Amazon is an extrapolation.
