Man living in the modern world is constantly exposed to changes: social, cultural, economic, technological, etc. According to Piotr Sztompka, the perceived changes concern primarily the transformations taking place in the organisation of the public life and in the patterns of thinking and acting in time; the modification or transformation of the way in which the society is organised; the variability of the relations between individuals, groups, organisations, cultures and communities taking place in time; transformations of behavioural patterns, social relations, institutions and the social structure in time (Sztompka, 2005, p. 22). Continuous changes are taking place in the social structure, as mentioned by Sztompka. This is visible, inter alia, in the phenomenon of population ageing which is common in many countries. The demographic changes confirm the fact of population ageing in the countries of the Visegrád Group, which is determined by the increased life expectancy as well as a drop in the birth rate.
