All I know is that in the 35 years I've lived in inner city Liverpool, I'm now 72, I have only one problem with crime and that is when someone broke into my shed to steal an old anorak I used for painting the outside of our semi. No problem with any of the cars parked outside. And I am not the only one.
My cousin who lives down south, once told me a few years ago when she worked for the ONS , they collect data from the Police, Insurance companies, Utility firm etc etc.
Yes, I understand about your point from people not bothering to report such matters, especially these days.
