Native American Population

[Gregory Matthews]

Native American Population:   " By, 1500, Native Americans may have numbered as many as 15 million in North America and spoke some 300 different languages.  Some native cultures, such as the Aztecs in Mexico and Incas in South America, were socially stratified and highly developed civilizations."  Allen C. Guezlo, writing in The History of the United States, 2nd Edition, Page 5.
