There are no published figures for the number of Singlish speakers. If we assume that most Singaporeans in their 30s and below (i.e. born from the mid/late 1970s onwards, when Singlish was present and evolving) would have acquired Singlish as small children, e.g. in the playground or from peers in school, this would comprise about half of Singapore's 4 million inhabitants. Add to that many Singlish users in the age range of 40-50, this would take the estimation of the number of Singlish speakers up to some 2-3 million.
