The category of Native American applies to the diverse group of people who lived in North America before European settlement. During the U.S. government's westward expansion, Native Americans were displaced from their land which had been their home for centuries. Instead, they were forced onto reservations which were far smaller and less productive. According to Brest, land belonging to Native Americans was reduced from 138 million acres in 1887 to 52 million acres in 1934. In 1990, the poverty rate for Native Americans was more than triple that of the whites and only 9.4% of Native Americans have completed a bachelor's degree as opposed to 25.2% of whites and 12.2% of African Americans.
