Blurred Stats (Part II)

U.K. Statistics Authority censures head of state prosecution service for “hugely” exaggerating rape conviction rate statistics

source

I recently blogged about how the U.K. Crown Prosecution Service (CPS) frequently inflates the rape conviction rate with its annual Violence Against Women and Girls crime report.

For instance, this year’s report boasts the “highest volumes ever recorded” of rape convictions, with a rise “from 2,689 in 2015-16 to 2,991 in 2016–17.” However, the accompanying data shows that those figures include “cases resulting in a conviction for rape, but also cases initially flagged as rape where a conviction was obtained for an alternative or lesser offence,” and “where a decision is taken to charge an offence other than rape, or where a rape charge is subsequently amended.”

Efforts via this blog to report the actual figures last year resulted in corrections in two major British newspapers, including a page two correction in the print edition of The Daily Telegraph.

Now comes news that the U.K. Statistics Authority has censured Director of Public Prosecutions, Alison Saunders, for “hugely” exaggerating the figures.

Via “CPS chief is blasted for claiming the number of rape convictions is more than double the real figure” by Martin Beckford, The Daily Mail, October 21, 2017:

Britain’s top prosecutor has been blasted by a watchdog for claiming the number of rape convictions is more than double the real figure.

Alison Saunders, the Director of Public Prosecutions, was warned that the hugely inflated figures in a report on violence against women were ‘misleading’.

She was told in a letter from the UK Statistics Authority that the true number of people convicted of rape last year was under 1,400. This is less than half the 3,000 she alleged in the report by the Crown Prosecution Service (CPS) earlier this month.

The huge gap is because the CPS includes crimes that were originally investigated as rapes but later downgraded to less serious offences.

Last night, TV company executive Leon Hawthorne, who complained about the statistics discrepancy, said: ‘Alison Saunders went on the media to boast about how more and more rapists are being found guilty. The problem is her figures are a calculated deception.’

Annual Violence Against Women and Girls crime report by U.K. state prosecution service inflates rape conviction rate statistics for second year in a row

Last year, I blogged about how the U.K. Crown Prosecution Service (CPS) inflated the rape conviction rate with its annual Violence Against Women and Girls (VAWG) crime report.

In a press release, the CPS claimed that in 2015-16 it convicted “more cases of rape…than ever before,” with “a rise in the rape conviction rate [from 56.9 per cent] to 57.9 percent.” Those figures were widely reported by the British press. However, a close look at the accompanying data showed that those figures included “cases initially flagged as rape where a conviction was obtained for an alternative or lesser offence” and “where a rape charge is subsequently amended.”

Efforts via this blog to report the actual figures resulted in corrections in two major British newspapers, including a page two correction in the print edition of The Daily Telegraph.

Earlier this week, the CPS released its 10th annual VAWG report. The report again boasts the “highest volumes ever recorded” of rape convictions, with a rise “from 2,689 in 2015-16 to 2,991 in 2016–17.”

The accompanying data also includes the caveat that “CPS data on successful rape prosecutions includes not only cases resulting in a conviction for rape, but also cases initially flagged as rape where a conviction was obtained for an alternative or lesser offence.” The data report further states that CPS figures include cases “where a decision is taken to charge an offence other than rape, or where a rape charge is subsequently amended.”

So far five major publications, The Guardian, BBC NewsThe Independent, The Times, and BuzzFeed News, have published stories quoting the CPS’ claims about “record” numbers of convictions.

I’ll ask all four about the inflated figures and blog the results.

The Independent publishes my corrections request re: Crown Prosecution Service’s skewed statistics on rape convictions

Last week, I blogged about the Crown Prosecution Service (CPS) having exaggerated the 2015-16 rape conviction rate.

Via a press release, the CPS claimed that it was “convicting more cases of rape…than ever before,” with “a rise in the rape conviction rate [from 56.9] to 57.9 per cent.”

These figures were widely reported in the UK press, including the Independent newspaper.

Via the WayBack Machine, the Independent’s Sept. 6 article

However, a close look at the CPS’ 2015-16 Violence Against Women and Girls crime report reveals that the rape conviction rate “includes cases initially flagged as rape [but] where a conviction was obtained for an alternative or lesser offence” and “where a rape charge is subsequently amended.”

On Sept. 17, I made a corrections request to the Independent regarding “Revenge porn prosecutions number ‘more than 200’ just 18 months after law change,” the newspaper’s Sept. 6 article which, as per the above screenshot, stated that “in 2015/16…There were a record numbers of rape prosecutions (4,643) and convictions (2,689).”

Yesterday, I received notification from the Independent’s readers’ liaison assistant Jane Campbell that the article has been updated.

Dear Mr Jones,

Thank you for contacting us via our online complaints form. We are always glad to hear from our readers, whether or not feedback is positive, and I am grateful to you for taking the time to get in touch about ‘Revenge porn prosecutions number ‘more than 200′ just 18 months after law change’ (6 September).

Your point is well taken and the article has now been changed to reflect that rape conviction figures also include cases where a conviction was obtained for an alternative or lesser offence.

I hope that, in spite of your concerns on this occasion, you will continue to read and enjoy The Independent. And please do not hesitate to contact me again in the future should cause arise.

With best regards
Jane Campbell

UK prosecution service fudges the statistics on rape

Earlier this month, the Crown Prosecution Service (CPS) released its annual Violence Against Women and Girls crime report.¹ Via a press release, the CPS claimed that it was “convicting more cases of rape…than ever before,” with “a rise in the rape conviction rate [from 56.9] to 57.9 per cent.”

Despite the CPS’ own admission that it “does not collect data which constitutes official statistics as defined in the Statistics and Registration Service Act 2007,” figures from the press release were reported in several mainstream newspapers, including the Guardian and the Telegraph.

the-guardian-violence-against-women-and-girls-crime-report

However, a close look at the report itself reveals that the rape conviction rate includes “cases initially flagged as rape [but] where a conviction was obtained for an alternative or lesser offence” and where a rape charge is subsequently amended.”

For example, the report states that there was a total of 2,689 rape convictions for the financial year 2015-16, yet according to statistics from the Ministry of Justice (MOJ),² there was only 1,297 rape convictions for the calendar year 2015 – a disparity of 1,392.

My questions:

• How many cases initially flagged as rape were later charged or convicted with a lesser crime? How many where the conviction was amended altogether?

• How many convictions were obtained in the period prior to the start of the financial year 2015-16? How many after the calendar year 2015?

Those are questions for a statistician better qualified than a C-grade maths student such as myself. In the meantime, I’ll ask the CPS about its methods of recording statistics and blog the results.

Stay tuned.

¹The report is also “inclusive of data on men and boys.”
²MOJ data “only includes cases where the final conviction was for rape.”
