Contemporary rural areas in Russia are are experiencing a profound systemic crisis characterized by persistent depopulation, institutional degradation, and intensifying socio-economic marginalization. Based on a comprehensive analysis of official statistics for the 2000–2025 period, this paper identifies a self-perpetuating mechanism of rural community decline, wherein the reduction of social infrastructure – specifically education, healthcare, and culture – serves not merely as a consequence but as a catalyst for further depopulation. The study empirically validates a regional typology of infrastructure transformation, distinguishing between suburban, intermediate, and peripheral zones. It demonstrates that traditional approaches to institutional “optimization” exacerbate social inequality and spatial polarization. As an alternative, an adaptive social service model is proposed, which integrates minimum accessibility standards, hybrid (inperson and remote) and mobile service formats, and differentiated regional development strategies. The scientific novelty of the research lies in the identification and description of the mutual reinforcement mechanism between demographic and institutional crises. Furthermore, it develops conceptual frameworks for overcoming the “vicious cycle” of rural degradation by adopting a paradigm that views the preservation of quality of life as the foundation for sustainable development.
