Now consider the Crime Survey for England and Wales, which shows that despite minor uptick in recent years, the rate of rapes are below past peaks even in the 2000's[1] (see e.g. figure 2), including for rapes. These are based on asking people, and so capture far more crime than police reports and are not affected by charging rates.

What you will see, however, is that the reports have dramatically increased. See figure 3. Combined with relatively static reported rates of rapes, this is good - it means a large proportion now do get reported.

But given the number of reports have drastically increased relative to the rate of crimes as reported in the crime survey, it is not surprising that charge rates have fallen, as it's at least plausible that a number of incidents that are now reported that wouldn't have been before are those incidents with insufficent evidence. (That doesn't mean it's not problematic that the charge rates have dropped, of course)

What is clear, is that there is no evidence for the contention in the comment I replied to. It's a common far-right talking point used to sow fear. I'm not suggesting that commenter who posted it are intentionally pushing far-right talking points - I know plenty of people on the left who have been tricked into repeating this as well. But they are unambiguously talking points that are being abused by the UK far-right to push a narrative of a collapsing society that does not match reality.
