Aging of the population is one of the dominant trends in the XXI century. It is expected that by 2050, more than a quarter of the world's population (27%) will be 65 years or older. Increase of older persons' proportion in the population of most countries entails a change in the scale and structure of morbidity requiring higher costs for medical care, social security, including pensions. Ageing appears on the international agenda for more than 30 years. The Human Rights treaty bodies rank the elderly as a vulnerable group, who are more susceptible to various forms of discrimination. However, there is currently no any international legal instrument specifically dedicated to the problems of protection of the elderly at a time when their discrimination and stigmatization is a very common phenomenon.
