The Evil Ex's family lived in a part of Nottingham that was like that. Then again his older brothers had been to prison (armed robbery and GBH) and his younger brother was known to the police for vandalism and anti-social behaviour so they fit right in.

Never lived anywhere like that though.
I wouldn't leave anything I valued outside overnight in the rougher parts of town, but I'd consider that taking care rather than fear of crime. Talking an unlocked bike etc, not Christmas lights or a BBQ out back. There's occasional vandalism (telephone boxes, bus shelters, new trees) but it's not yet endemic. And not common even where I live - which isn't considered high class.

In some ways I think the farmers get it worst because they are easy targets with expensive machinery sitting in isolated locations. Farmers might be armed, but it doesn't seem to help much. You simply cannot stay up all night, every night when you're working the land. And those are organised gangs as opposed to petty criminals.
