Census data is helpful in determining mixed ethnicities, but unfortunately, so many people are left out of the Census each time it rolls around. You have to figure that the actual number of non-caucasian (including mixed ethnicities) people in the United States is much higher than the Census shows.
Living in and around New York all my life, I can honestly say that I don't have one single picture in my mind of a New Yorker; rather, I have several. Italian guys in pizzerias, Puerto Ricans marching in the Puerto Rican Day Parade, Indian and Pakistani taxi drivers, African-Americans gathering at the Apollo Theater in Harlem...these are all images I have of New Yorkers. Not to mention the ubiquitous businessmen and women of all ethnicities walking around at all hours of the day. One may perceive my images as stereotypical, and in some ways they are, but that is not necessarily a bad thing. My wide range of pictures are there to prove a point: that when you combine such a broad scope of ethnicities and cultures into one confined space, mixing is bound to happen.
Personally, I think integration is a good thing. Even on a purely social level, it's much cooler to get to know someone who has multiple heritages. It gives two people a great deal more to talk about, and it's fascinating.
No, I like women.
