Peer pressure exists wherever one may live. It just may concern different things: fashion, hobbies, choices of entertainment, “wants and desires”, habits ect.
I have lived in small areas and larger cities, been to many different cities including NY, and have gone to camp and met all types. So I think I can back up what I say with experience. If it is a new community, with few choices in schools and shuls, I have found that there is less peer pressure than in larger areas. Children learn to get along with others, even if they aren’t exactly the same. There is no pressure to buy the latest X or this toy or that brand Y. If the other child will not play with your child because they do not own this, then the other child will not have a playmate and will change. In town, when children have more choices for friendships, they can be pickier and then the pressure starts.
