30647 Ulwa 100-999 300 1,800 The figure of 600 is a rough estimate. It is based on an estimated total population of 1,800 for the four villages where Ulwa is spoken. It is assumed that only about 35% of this population is fluent in the language, since it is generally only used by people over 30 years of age, and the 0-30 year-old demographic represents about 65% of the rural populations in PNG (according to the 2011 PNG census). Of course, some people younger than 30 are also fluent, but this figure should be offset by those people older than 30 who are not speakers (mostly immigrants from other language communities).
