The level of pension provision of the population is a guarantee of social security of the person

Relevance of the research topic. Various social cataclysms of the twentieth century and recent decades, such as the two world wars, the hybrid wars, the spread of the COVID-19 pandemic, have led to the emergence of the concept of "social security" in the twentieth century. The latter, given the socialization of all spheres of human life, plays a key role in the entire national security system. In a democratic society, the interests of social security of the individual and the state as a whole must be reconciled and harmoniously balanced. In the legal field of Ukraine there is no official definition of the category "social security", and the term "social security" has recently entered into scientific and political circulation. In Ukraine, a new stage of legislative regulation of relations in the sphere of pension provision began with the adoption of the Constitution of Ukraine. Only the laws of Ukraine define the basis of social protection, forms and types of pension provision (paragraph 6 of Article 85). Article 46 of the Constitution provides for the right of citizens to social protection, to ensure them in case of full, partial or temporary loss of working capacity, loss of the employer, unemployment from circumstances beyond their control, as well as in old age and other cases provided for by law [1]. Article 46 of the Constitution provides for the right of citizens to social protection, to provide them in case of complete, partial or temporary disability, loss of breadwinner, unemployment due to circumstances beyond their control, as well as in old age and in other cases provided by law [1]. Since the right to a pension can arise throughout a person's life, starting from birth, replacing lost income with a pension is important for the well-being and prevention of poverty of certain categories of the population. As the de jure three-tier pension system de facto remains only two-tier with a predominant share of first-tier pension benefits, it remains relevant to study the level of pension provision from the solidarity system, which is built on the principle of intergenerational solidarity. Problem solving. The need for a comprehensive study of the issue of pension provision, conceptual definition of its mechanisms (instruments) from different levels of the pension system, especially in the conditions of aging of the nation, is conditioned by the need to improve practice and raise the level of pension provision in Ukraine as a guarantee of social security
