"In 2004 there were estimated to be less than 500 speakers of the Manyjilyjarra language. There may be much less than that number now as many children of Manyjilyjarra people speak Martu Wangka, which combines elements of the Manyjilyjarra and Kartujarra languages with influences from the Warnman, Nyiyaparli and Putijarra languages. As such, children of Manyjilyjarra speakers may not speak a pure form of the language and may be unable to identify Manyjilyjarra elements."

"Over 200 speakers at Punmu, Parnngurr, Jigalong and also now in Port Hedland and towns on the desert fringe. Marsh (1990 p.c.) notes that there are over 700 speakers of Martu Wangka, with nearly 400 Manjiljarra speakers."
