From 1500 to 1600, Europe experienced a population decline, while the Americas, China, and India saw population growth. Europe's population decline was mainly due to factors such as wars, plagues, and economic instability. On the other hand, the Americas, China, and India experienced population growth due to factors such as increased agricultural productivity, technological advancements, and relatively stable political conditions.
