In 2014, the GSS asked respondents if they "feel more like a citizen of the world than of any country". The following table shows the percentages of respondents who either disagreed or strongly disagreed with the sentiment. Thus the higher the percentage, the less globalist and more nationalist a group's identification.
Another way to read "citizen of the world" in this context, though, is as someone with hostility to the concept of the United States as a unified political entity. As is often the case with broad survey questions like these, the list of potential responses is not as clarifying or exhaustive as we'd like them to be. I don't identify much as a citizen of the United States but I identify even less as a citizen of the world. There simply isn't an obvious response indicative of localism here. If the choice is dichotomous, though, I'm coming down as a citizen of the country rather than of the world:
|Less than high school||31.2|
|High school grad||50.0|
The young, the non-white, the poorly educated, the lower classes, the foreign-born, the politically leftist--these are the people who don't feel much attachment to the idea of being American citizens. Demography is destiny, and our destiny looks to be a disunited America. Remove 30 million, virtually all of whom fall into one of these groupings, and there might be a snowball's chance in hell of avoiding that fate, but even then I doubt it.
