AbstractThe case of Catalonia has often been pointed out as a case of success in the field of language policy, based onthe improvement in its legal situation, the increase in the number of people who know it, and the extension of its use in certainfields. To contribute to a complete evaluation of the current language policy model in Catalonia, this article assesses theevolution of the first languages of the population over the last fifteen years. The study shows that during this period, despitesome oscillations, Catalan has remained in stable numbers of L1 speakers in absolute terms, thanks essentially to very strongpatterns of intergenerational transmission in both linguistically homogeneous and mixed couples. However, significant immigrationduring this period has substantially increased the weight of other languages and, to a lesser degree, Castilian, so that inrelative terms Catalan has been reduced as a first language between 2003 and 2018.
