Rather than equating the terms 'local' and 'cosmopolitan' with geographical areas (rural and urban respectively), sociologist Wade Clark Roof suggests that these terms refer to character types who can be found in a diversity of settings in the United States. Locals are strongly oriented toward community or neighborhood, favor commitments to primary groups (family, neighborhood, fraternal and community organizations), tend to personalize their interpretations of social experience, and are more traditional in their beliefs and values. Cosmopolitans, on the other hand, are oriented toward the world outside the residential community, prefer membership in professional or special interest organizations, and are more open to social change and more tolerant of diversity in belief than locals. While a disproportionate number of locals are found in smaller communities, studies indicate that other factors - such as length of residence in a community, age, and educational level - play an even stronger role in determining orientation.
