The term "rez" is often used as a shorthand for "reservation," referring to land that is managed by a Native American tribe under the U.S. Bureau of Indian Affairs. These reservations are areas where tribes have some degree of self-governance and can maintain their own cultural practices, legal systems, and economic activities. The specifics of life on a reservation can vary widely depending on the tribe, location, and available resources. Some reservations face significant challenges such as poverty, limited access to healthcare, and education, while others have found ways to thrive through various enterprises like casinos, tourism, and natural resource management.
