NAV meaning in Regional ?

The Navajo (; British English: Navaho; Navajo: Diné or Naabeehó) are a Native American people of the Southwestern United States.

At more than 399,494 enrolled tribal members as of 2021, the Navajo Nation is the largest federally recognized tribe in the U.S. (the Cherokee Nation being the second largest); the Navajo Nation has the largest reservation in the country. The reservation straddles the Four Corners region and covers more than 27,000 square miles (70,000 square km) of land in Arizona, Utah and New Mexico. The Navajo language is spoken throughout the region, and most Navajos also speak English.

The states with the largest Navajo populations are Arizona (140,263) and New Mexico (108,306). More than three-quarters of the enrolled Navajo population resides in these two states.

Besides the Navajo Nation proper, a small group of ethnic Navajos are members of the federally recognized Colorado River Indian Tribes.
