Transnational research refers to studies that involve collaboration or data collection across multiple countries or regions. This approach allows researchers to compare and contrast data from different cultural, economic, and social contexts, providing a more comprehensive understanding of a particular topic or issue. Transnational research often requires interdisciplinary collaboration and the use of diverse research methods to address complex global issues effectively. It can encompass a wide range of topics, including health disparities, migration patterns, environmental sustainability, and international trade relationships.
