The article examines the impact of demographic policy on the financial stability of rural settlements' budgets in the Republic of Crimea, which operates within the legal framework of the Russian Federation. Demographic policy, aimed at regulating population size and structure, plays a significant role in the socio-economic development of rural areas, with rural settlements serving as administrative units. In recent years, changes in population size, migration flows, and population aging have posed substantial challenges for the budgets of rural settlements, increasing the burden on maintaining social and infrastructure components. The article analyzes the influence of demographic factors such as the reduction in the working-age population, the growing proportion of elderly citizens, and migration trends. These factors affect the expenditure side of the budget, increasing costs for healthcare, social security, and infrastructure development. Given the resource limitations of local budgets, there is a pressing need to develop a set of measures aimed at enhancing the revenue streams for the budgets of rural settlements and the Republic of Crimea, as well as optimizing expenditures. The recommendations presented in the article include measures to increase budget revenues for rural settlements, achievable through improvements in tax administration and the attraction of federal subsidies for programs supporting and developing these areas. An essential aspect is the development of social infrastructure and support for the working-age population through employment programs and social initiatives, which contribute to reducing migration rates and enhancing demographic resilience. The article highlights key issues and provides recommendations aimed at creating the prerequisites for budgetary stability in rural settlements amidst demographic changes. The proposed approach should be based on balancing demographic and financial policies in the Republic of Crimea to ensure the sustainable socio-economic development of rural settlements.
