Navajo is the most widely spoken Native language

ktiv reports that 169,000 people report speaking Navajo in the home "at a time when some tribes have lost their native tongue or are struggling to retain the words of their ancestors." However encouraging the finding, the article goes on to explain that, in the U.S., the "population of Navajos is well over 300,000. For every one who speaks the language, one doesn't - and those are likely younger Navajos." Good overview of some of the reasons why Native languages today are extinct or in danger of exinction.
