He added that the report also showed that a significant number of false allegations of rape (and domestic violence) "involved young, often vulnerable people.
About half of the cases involved people aged 21 years old and under, and some involved people with mental health difficulties.
It showed that in 35 cases authorities prosecuted a person for making a false allegation, while they brought 5,651 prosecutions for rape.
Keir Starmer, the head of the CPS, said that the "mere fact that someone did not pursue a complaint or retracted it, is not of itself evidence that it was false" and that it is a "misplaced belief" that false accusations of rape are commonplace.

First, the police continue to misapply the "no-crime" or "unfounding" criteria. Rumney notes that some officers seem to "have fixed views and expectations about how genuine rape victims should react to their victimization".
He adds that "qualitative research also suggests that some officers continue to exhibit an unjustified scepticism of rape complainants, while others interpret such things as lack of evidence or complaint withdrawal as 'proof' of a false allegation".
Rumney's second conclusion is that it is impossible to "discern with any degree of certainty the actual rate of false allegations" because many of the studies of false allegations have adopted unreliable or untested research methodologies.
The researchers noted that some of these classifications were based simply on the personal judgments of the police investigators and were made in violation of official criteria for establishing a false allegation.
Closer analysis of this category applying the Home Office counting rules for establishing a false allegation and excluding cases where the application of the cases where confirmation of the designation was uncertain reduced the percentage of false reports to 3%.
The researchers verified, whenever possible, for all of the complainants who recanted their allegations, that their new account of the events matched the accused's version of events.
After reviewing the police files, Kanin categorized the false accusations into three broad motivations: alibis, revenge, and attention-seeking.
