Current Usage The Navajo language is widely used by the Navajos of all ages, with over half of the Navajo people using it at home. Many Navajo still transmit their parents native language to their children as their mother tongue. Because of this the Navajo are one of the few American Indian tribes in territory that used their native language for everyday communication. However, the language is in decline, especially in urban areas outside reservations and more young people begin to use English. Even within reservations census indicate that between 1980 and 1990 the proportion of Navajos between five and seventeen years who used only English rose from 12 to 28 . For 2000 the figure rose to 43 .
