Given the forthcoming near certain massive disappearance of languages during the twenty-first century, scholars have tried to identify the causes that are leading this process. Among those given, the number of speakers has been considered one of the most important predictors for the future of a language, and different “safety thresholds” have been proposed. However, examination of several sociolinguistic aspects in a fairly large sample of languages worldwide suggests that there is no direct relationship between the number of speakers and the probabilities of survival of a language. In this article, we will show that the number of speakers cannot be considered the only, not even the most important criterion, when trying to anticipate language survival or death. Instead, natural transmission and intergenerational use are shown to be better predictors. We will use data on more than 525 languages, collected by the Amarauna Languages group of the UNESCO Center in the Basque Country, with the purpose of writing a report on the current sociolinguistic situation of the world languages (Martí et al. 2005).
