Oh well you could look at the no-crime figures.
From 2011 here:
here
"Data supplied to BBC News shows the proportion of rapes dismissed by the police as "no crime" varies between 2% and 30%."
From that you can work out which areas of the country are full of women and girls who are bloody liars, I think.
Or something.
Oh incidentally: from here, on no criming sex offences
"Patrick told MPs that his research showed 70% of rape allegations that were classed as not meriting investigation were wrongly dismissed. He said he had spoken to his force's crime management unit, which ran statistical and recording policies.
Patrick told the committee: "A preference had developed to try to justify 'no crime' on the basis of mental health or similar issues of vulnerability or by saying that the victim has refused to disclose to them."
Committee chair Bernard Jenkin asked: "This would finish up with trying to persuade a victim that they weren't raped, for example?" Patrick responded: "Effectively, yes.""
Also attitudes such as this amongst the police have been problematical here:
"The IPCC inquiry found individual and systemic failings in the Met. In one police report a detective constable dealing with the July 2007 victim had written: "The victim cannot remember anything past getting in the cab. It would seem unlikely that a cab driver would have alcohol in his vehicle, let alone drug substances." Other findings included:
• Officers adopting a mindset that a black-cab driver "would not commit such an offence", and failing to challenge Worboys, who was identified by his cab number in CCTV footage in July 2007, over his account.
