Demographics
Laurel Watkins noted in 1984 based on Parker McKenzie's estimates that only about 400 people (mostly over the age of 50) could speak Kiowa and that only rarely were children learning language. A more recent figure from McKenzie is 300 adult speakers of "varying degrees of fluency" reported by Mithun (1999) out of a 12,242 Kiowa tribal membership (US Census 2000).
The Intertribal Wordpath Society, a nonprofit group dedicated to preserving native languages of Oklahoma, estimates the maximum number of fluent Kiowa speakers as of 2006 to be 400.
