The aim of this study is to show social cohesion as a prerequisite for sustainable economic and social development. Social cohesion is a broad concept whose creation is influenced by numerous policies that encourage social inclusion and social mobility or develop social capital. To measure the degree of social cohesion, it is important to monitor both objective and subjective indicators. A key factor for the successful functioning of cohesive societies is a high degree of trust - where there is no trust, divisions, instabilities and conflicts increase, which has the effect of slowing down or stopping economic growth. In societies without social cohesion, transaction costs are too high, and economic growth is unsustainable. Strong institutions are a prerequisite for the development of social cohesion in society and they should ensure that citizens are involved in social processes, that social agreements and regulations are implemented, and that they create a framework for economic progress, as well as a sense of well-being and fairness in society.
