Cultural clusters is a conceptual framework and analytical approach used to group countries, regions, or populations based on shared cultural dimensions, values, beliefs, and practices. This concept investigates patterns of cultural similarity and difference across distinct groups, providing a systematic means to understand cross-cultural variations, predict behaviors in international contexts, and inform strategies in fields such as international business, organizational behavior, and cross-cultural communication. Its significance lies in simplifying the complexity of global cultural diversity into manageable categories for comparative analysis and practical application.
