But for now, I just wanted to point towards this neat little Guardian article on Crime Statistics which I think summarises things really well.
Reported rapes leapt 29% in the latest figures, with more than 22,000 reported to police last year. However, according to both the ONS and the minister, Norman Baker, this rise is almost certainly explained by a greater willingness of victims to report incidents, whether recent or historic, helped, perhaps, by some improvements in police practices at the point of report. The detailed analysis of intimate violence is published annually in February. In 2012-13 the proportion of adult women who had experienced any sexual assault in the previous 12 months was at 2%, the lowest since records began.
Paradoxically an increase in reported rape is a very, very good thing. I long to see this figure falling, but only because the actual number of offenses is falling and not because (for lots of reasons) they remain unreported. I think a big step towards making sexual offenses rarer in society is seeing more victims feeling able to report it.
