Does everyone keep to themselves more here?

Mid 20’s F, lived in 3 states in the Midwest and south before this. It’s only been a few months but I already feel so isolated and was wondering why, but I am curious if anyone else felt the same way. I’m used to talking to strangers in the street, compliments from people I don’t know, making friends anywhere and getting approached when I go out. Here, I have literally not talked to anyone unless I make the first approach, and even then it feels like a dead end. It’s such a stark contrast to everywhere else I’ve lived and am going crazy trying to figure out how to make friends/meet people!
