As our world gets more diverse, understanding culture and cultural differences in interpersonal communication becomes increasingly important. Consider, for example, cultural diversity in the United States. In 2011, more than 50 percent of all births in the United States were nonwhite—including Latino, Asian, African American, and mixed-raced children (U.S. Census Bureau, 2012). International student enrollments in the United States are also on the rise (Institute of International Education, 2011). This means that your classmates are just as likely to be from Seoul as Seattle. Plus, with all the smartphones and tablet computers available, we have easy access to people around the world. This enables us to interact with others and create interpersonal relationships on a global level in a way never possible before. As our daily encounters increasingly cross cultural lines—making us more aware of diversity—the question arises, what exactly is culture?
