RP servers are community servers, where admins probably try to enforce rules encouraging RP. Depending on their vision, RP can be very different from server to server. Some like it very strict, some take it very loosely, but I guess it's a good server to look at when you want to avoid being shot on sight and maybe enjoy playing a character.
What you are probably looking for are more hardcore RP servers, if you actually want to live in a city. You can use the search function in the server brwoser for roleplay, RP or hardcore RP/roleplay, or maybe even google, some of the larger one have websites.
