Today's societies face many challenges that are closely linked to changing values, the weakening of values or the emergence of new values. Values not only guide people between right and wrong, but also represent a kind of cohesive force for communities. If these values are shaken, social order and coexistence may be endangered. My study aims to provide a brief summary of norms, values and social challenges in the 21st century. Our rapidly changing world, the fast flow of information and social transformation influence our everyday lives, which has made individual and community adaptation stronger. This study aims to provide a brief summary of the changes taking place in society in the 21st century, the greatest challenges it faces, and the issues that arise in relation to social norms and rules, integration, and cooperation. Radical changes in values are taking place in modern society. Traditional values such as family, work, faith, patriotism, responsibility, and honesty are gradually receding into the background and being replaced by individual rights, self-fulfillment, consumption, and freedom/individualism.
