Which group has experienced population decline from 20 million to 600,000, and faces high rates of negative socioeconomic outcomes?

The group that has experienced a staggering population decline from 20 million to 600,000 and faces high rates of negative socioeconomic outcomes is American Indians. This significant reduction in population can largely be attributed to historical factors such as colonization, forced relocation, and the impact of diseases introduced by Europeans. Furthermore, the ongoing effects of systemic discrimination and socioeconomic challenges have left many American Indian communities facing high rates of poverty, unemployment, and health disparities.

This context is essential because it highlights the unique historical and social circumstances that have shaped the experiences of American Indians in the United States, leading to both their demographic decline and the persistent socioeconomic difficulties they encounter today. Understanding these factors is crucial for addressing the needs and rights of American Indian peoples in contemporary society.
