Comparison of population growth in (former) European colonies 1500-1998

The European colonization of the Americas and Oceania introduced new diseases to biologically defenseless societies, and this resulted in a significant population decline among the indigenous populations in the early years of settlement. In the first two centuries of the Americas' colonization alone, the indigenous population dropped to just 10 percent of its pre-colonial level, with smallpox considered to have been the most destructive. Additionally, the indigenous populations of the Caribbean and Tasmania were virtually all wiped out.

Growth through migration

It was only through European settlement and the importation of African slaves that the population of the Americas began growing in the 18^th century, while European and (to a lesser extent) Asian migration to both continents then saw this increase further between 1820 and 1950. However, growth peaked in Latin America and the Caribbean during the late-1900s, due to their relatively later demographic development.

International comparison

Compared to the rest of the world, annual average growth rates in these colonized and settled regions were much higher, due to high rates of migration and the fact that their starting populations were much smaller. While much of Africa and Asia was also colonized by Europeans, it was less likely to be settled in the same manner, and these populations were also familiar with the diseases carried by Europeans. The most significant demographic developments for these continents was the onset of their demographic transitions, which coincided with the periods of population growth.
