Yankunytjatjara to be endangered based mainly on the Census of 1996. In 2005 the National Indigenous Language Survey, based on a more comprehensive survey, concluded that Yankunytjatjara was 'definitely endangered'. Naessan, using the 2003 UNESCO framework, gave a mark of 22/23 out of 35 (in its most condensed spot), quite a low score. If some factors that Naessan feels are unimportant in most indigenous languages are ignored, Yankunytjatjara scores 14/15 out of 20 (in its densest area). However, he argues that since recent surveys have included these factors, they may be more helpful for cross referencing. To a lesser extent he feels that, since Western Desert people own some media sources (radio station etc.), such factors should be included. He concludes a 57–65% vitality. Both schemas indicate that Yankunytjatjara shows symptoms of endangerment (although how endangered is a subject of debate), which coincides with the beliefs of the Yankunytjatjara elders that Naessan spoke with, as well as with the assessments of most linguists who have worked in the area.
