Abstract
International migration from small populations may have long-term cultural and social consequences. American Samoa (AS) is a small island territory whose scale (N = 55,519; 77 mi2, 2010) offers a magnified view of how migration impacts a population via interconnected economies. This article examines effects of international migration on population growth, population distribution and age structure in AS. American Samoa’s population continues to increase but at a fraction of the rate predicted by natural increase; furthermore, without heavy out-migration, AS could have an unsustainable population density of nearly 1000 individuals/mi2. It is argued international migration has reduced population pressure and contributed to maintenance of normally unsustainably high birth rates while also being a negative influence on internal development.
