From the 16th through the 19th centuries, the population of Native Americans declined in the following ways: epidemic diseases brought from Europe; violence and warfare at the hands of European explorers and colonists, as well as between tribes; displacement from their lands; internal warfare, enslavement; and a high rate of intermarriage. Most mainstream scholars believe that, among the various contributing factors, epidemic disease was the overwhelming cause of the population decline of the American natives because of their lack of immunity to new diseases brought from Europe. With the rapid declines of some populations and continuing rivalries among their nations, Native Americans sometimes re-organized to form new cultural groups, such as the Seminoles of Florida in the 19th century and the Mission Indians of Alta California. Some scholars characterize the treatment of Native Americans by the US as genocide or genocidal whilst others dispute this characterization.
Estimating the number of Native Americans living in what is today the United States of America before the arrival of the European explorers and settlers has been the subject of much debate. While it is difficult to determine exactly how many Natives lived in North America before Columbus, estimates range from a low of 2.1 million (Ubelaker 1976) to 7 million people (Russell Thornton) to a high of 18 million (Dobyns 1983). A low estimate of around 1 million was first posited by the anthropologist James Mooney in the 1890s, by calculating population density of each culture area based on its carrying capacity.
In 1965, the American anthropologist Henry F. Dobyns published studies estimating the original population to have been 10 to 12 million. By 1983, he increased his estimates to 18 million. Historian David Henige criticized higher estimates such as those of Dobyns', writing that many population figures are the result of arbitrary formulas selectively applied to numbers from unreliable historical sources. By 1800, the Native population of the present-day United States had declined to approximately 600,000, and only 250,000 Native Americans remained in the 1890s.
Chicken pox and measles, endemic but rarely fatal among Europeans (long after being introduced from Asia), often proved deadly to Native Americans. Smallpox epidemics often immediately followed European exploration and sometimes destroyed entire village populations. While precise figures are difficult to determine, some historians estimate that at least 30% (and sometimes 50% to 70%) of some Native populations died after first contact due to Eurasian smallpox.[44][45] One element of the Columbian exchange suggests explorers from the Christopher Columbus expedition contracted syphilis from indigenous peoples and carried it back to Europe, where it spread widely.[46] Other researchers believe that the disease existed in Europe and Asia before Columbus and his men returned from exposure to indigenous peoples of the Americas, but that they brought back a more virulent form.
In the 100 years following the arrival of the Spanish to the Americas, large disease epidemics depopulated large parts of the Eastern Woodlands in the 15th century. In 1618–1619, smallpox killed 90% of the Native Americans in the area of the Massachusetts Bay. Historians believe many Mohawk in present-day New York became infected after contact with children of Dutch traders in Albany in 1634. The disease swept through Mohawk villages, reaching the Onondaga at Lake Ontario by 1636, and the lands of the western Iroquois by 1679, as it was carried by Mohawk and other Native Americans who traveled the trading routes. The high rate of fatalities caused breakdowns in Native American societies and disrupted generational exchange of culture.
After European explorers reached the West Coast in the 1770s, smallpox rapidly killed at least 30% of Northwest Coast Native Americans. For the next 80 to 100 years, smallpox and other diseases devastated native populations in the region. Puget Sound area populations, once estimated as high as 37,000 people, were reduced to only 9,000 survivors by the time settlers arrived en masse in the mid-19th century. The Spanish missions in California did not have a large effect on the overall population of Native Americans because the small number of missions was concentrated in a small area along the southern and central coast. The numbers of indigenes decreased more rapidly after California ceased to be a Spanish colony, especially during the second half of the 19th century and the beginning of the 20th (see chart on the right).
Smallpox epidemics in 1780–1782 and 1837–1838 brought devastation and drastic depopulation among the Plains Indians. By 1832, the federal government established a smallpox vaccination program for Native Americans (The Indian Vaccination Act of 1832). It was the first federal program created to address a health problem of Native Americans
