you are almost certainly wrong

it is likely true that people tend to be friends with, and are surrounded by, similar people. So there are, say, 5% of americans who are engineers, but it so happens that 80% of my acquaintances are engineers just as I am. That is because I met them in school, at work... Similar thing goes for religion, people will have a tight social circle from church, communities tend to have similar social views and so on...
