Why do people who live in rural areas look different than those who live in the city?

I observed that people who live in my local village look different than those who live in the city. What I mean is that their skin and hair looks different. The have blonde/brown hair that looks like the kind of hair upper class people have. The people in the cities have black hair and their faces are less defined. Imagine the chav look. It's difficult to explain what I mean but there's definitely something different genetically about the two groups. It's like the people in the city reproduce without any kind of attention given to what their children will look like. In the poorer town next to me, the people are short and generally ugly due to interbreeding. I don't get why the people in the first village I mentioned look more attractive and upper class? You may not have noticed this because you probably aren't as observant as I am. This interests me because I find people with brown/blonde hair attractive. I also observed that the father of a child with blonde/blonde hair has black hair and the mother has blonde hair. The father must have a recessive blonde gene since I always thought black is dominant. Forgive me, my knowledge on genetics is terrible which is why I'm posting this thread.
