Pension provision in the system of social protection of the population

A large number of works in the scientific literature are devoted to the study of pensions in the social protection system, because today the issue of providing social guarantees to the population is very painful. Today's pension system in Ukraine operates in conditions of constant financial stress, instability and requires constant improvement as it is unable to provide citizens with a decent standard of living and therefore needs to be reviewed and reformed. Reforming socio-economic processes necessitates comprehensive public administration of reforms in the pension system by improving organizational and economic mechanisms. 
Pension provision is an important component of Ukraine's economic system. Pension rights are one of the basic social rights guaranteed by the Constitution of Ukraine and the laws of Ukraine, which are not only proclaimed or declared, but also implemented and apply to everyone. 
State-funded pension benefits are important factors in determining the living standards and well-being of the poorest and are designed to prevent poverty, meet basic needs and maintain a normal standard of living after losing one's job. 
The article considers the functioning of the pension system in Ukraine, namely, the need and composition of pensions, evolutionary processes, economic nature, as well as sources of formation of the Pension Fund and the use of funds. The need to amend the legislation of Ukraine to reform the pension system in Ukraine has been identified. 
Scholars' views on the interpretation of the concept of "pension provision" and "social protection system" are systematized. Particular attention is paid to the study of the constituent elements of the social protection system, which includes: social assistance, social security, social insurance. The three-level pension system in the context of the components of social protection subsystems is also studied.
