Although indigenous people are the original inhabitants of the Americas, they are minorities throughout practically all of its modern countries. The exact numbers change depending on your data source, but only Bolivia and Guatemala could legitimately claim that their populations consist mostly of indigenous people.
In some countries, the percentage of indigenous people is negligible. Puerto Rico, for example, counts indigenous people as being somewhere between 0 and 0.2 percent of its population. In Brazil, the biggest and most populated country in Latin America, the indigenous population is about 900,000, or a mere 0.4 percent of its total inhabitants.
The result is that indigenous issues in North, Central and South America are, usually, not even an afterthought. That reality allows organizations, governments, settlers, and multinational corporations to regularly threaten the well-being of indigenous populations with few repercussions.
