    "abstract": "Recently, individual-based models originally used for biological purposes\nrevealed interesting insights into processes of the competition of languages.\nWithin this new field of population dynamics a model considering sexual\npopulations with ageing is presented. The agents are situated on a lattice and\neach one speaks one of two languages or both. The stability and quantitative\nstructure of an interface between two regions, initially speaking different\nlanguages, is studied. We find that individuals speaking both languages do not\nprefer any of these regions and have a different age structure than individuals\nspeaking only one language.",
