A rural agrarian society is a community primarily focused on agriculture as the main source of livelihood and cultural identity, characterized by small-scale farming and a close-knit social structure. These societies typically have limited technological advancements and rely heavily on traditional farming practices. The connection to the demographic transition model is significant as these societies often represent the initial stages of population growth, where high birth rates and declining death rates lead to rapid population increases, before transitioning to more industrialized systems.
