There is a need to be careful about crime figures. A for instance. It was noticed that crime figures increased along with people having phones installed to such an extent that it could be viewed that land lines were the cause of the crime.
Obviously not - more crime was reported. Detection methods can improve. But something about society can change them as well. Might just be that increases are localised into more densely populated areas.
There is plenty of info on the ONS site if anyone wants to look into it.
