For the Americas (Chart 1), the dramatic population decline between 1500-1750 primarily resulted from the devastating impact of European colonization. Disease played a crucial role, as indigenous populations had no immunity to Old World pathogens like smallpox and measles.

This growth can be attributed to several factors including European immigration during the Industrial Revolution, improved agricultural techniques, and better medical understanding. The slave trade from Africa also contributed significantly to population growth, though this represents a tragic forced migration.
