I prefer eastern animation. The most influential reason is that this type of animation usually has an ongoing story/plot and isn't episodic. The story is what's most important to me, and American cartoons almost never have a firm plot and are episodic, though I do enjoy some shows like Dexter's Laboratory.
I'm 22 and I live in Texas as of last month.
By the way, if you are doing this for a dissertation like for a PhD or something I personally think the results you get here will be crap. First of all, your selection group (us) is likely to be completely biased towards anime because these are anime forums. Second, the responses you get are totally optional, so you'll likely get responses from only certain types of people. If you are planning to use this data for a serious study, don't.
