| contents | <p>The demographic system model is widely used in system dynamics <br>textbooks as an introductory example, yet most sources present only a static diagram without exploring its dynamic behavior or sensitivity to parameter changes. This paper implements the model in three environments — Vensim PLE, AnyLogic PLE, and Excel — to verify its correctness and analyze how variations in birth and death rates affect long‑term population dynamics. <br>The results show that the model exhibits strong sensitivity to the adult death rate, leading to sustained growth or decline depending on parameter values. The model serves as a foundation for more complex socio‑economic systems, such as those linking population dynamics with housing markets, credit availability, and labor conditions.</p> |
