The methodology implies modern methods of hierarchical analysis and analysis methods. The reason for choosing this topic is accompanied by the fact that, because demographic factors significantly affect the stability and security of the development of the region, the problem of ensuring demographic security, in particular in terms of identifying and tracking changes in key threats, is relevant and important for the further restoration of human resources. According to the results of the study, the features of the transformation of the main threats to demographic security and sustainable development of a particular region were determined. A response level matrix was proposed for each of the identified threats in order to counteract the most impact and further reduce the pace of implementation of activities. Research has limitations. The fact that as a result of hostilities, a small number of regions can be the object of research. In the future, we should consider the demographic security and sustainable development of regions that do not have the influence of military actions and compare them with our research results. Keywords: sustainable development, security, region, threats, demographic security 1. INTRODUCTION The technological progress of the last decade did not refute but only contributed to the assertion of the opinion that the main wealth of any state was and remains a person. The above is based at least on the fact that a person, using unlimited resources through knowledge and information, can provide the country's competitive advantages, creating high-tech products (works, services) through personal intellectual potential. Therefore, any decrease in human resources should be considered in terms of the loss of the potential for further socio-economic development and competitive positions in the geopolitical space. Due to the significance of the impact of such losses on national security, they are an object of demographic security with a corresponding specification of the content and tracking the impact of key threats for the further development and implementation of protective measures. The intensification of the struggle for human resources, which provide added value and form the basis for the transition to a post-industrial society, while at the same time deepening globalization processes that destroy obstacles to the free movement of a significant number of the population, requires focusing on ensuring demographic security as a priority for the stable and secure development of the country. In modern realities, the process of ensuring demographic security and sustainable development of the region can be defined as the development of the population of a certain country, in which the age, gender, and ethnic structure improve in accordance with national interests, providing for the preservation of integrity, sovereignty, independence, and geopolitical status. Ensuring demographic security consists in creating conditions for sustainable development not only of the state through the formation of the necessary quantity and quality of human resources but also of each person by satisfying his biological and social needs. That is, at the present stage of human development, demographic security implies the synchronous achievement of the interests of a single region and each citizen. The main purpose of the article is to identify the main threats to demographic security and sustainable development of the region in the context of military actions. At the same time, the structure of the article involves proving the relevance of the chosen topic, reviewing the literature, and presenting the main methods that form our research methodology. The results of the study and the discussion part of their discussion are presented separately. The final stage of our article is formed on the main studies, conclusions, and vision for further work.
