ONS decides to continue with inaccurate RPI calculation

Statistics agency chooses consistency over accuracy.

Against expectations and the recommendations of a number of influential economists, as well as its own consumer prices advisory committee, the ONS has decided not to change how the RPI – one of the two key indices measuring the rate of price inflation – is calculated.

The pressure to examine the index comes from the longstanding difference between the RPI and CPI measures of inflation. Except for the brief period in the midst of the recession, when both indices were recording deflation, RPI has consistently shown levels of inflation higher than CPI. Here's the chart for the last three years, for instance:

 

Some of that difference is due to the fact that the two indices measure subtly different things – RPI includes a broader measure of housing costs, for instance, and it ignores very high and low income households. But the ONS has known for a while that there is also a discrepancy caused by the different formulae used to calculate them.

The ONS began a consultation into whether and how it should eliminate this "formula effect", and has concluded that:

Use of the arithmetic formulation (known as the ‘Carli’ index formula) in the RPI is the primary source of the formula effect difference between the RPI and the CPI… This formulation does not meet current international standards.

So what's it going to do about it? Well, nothing:

The National Statistician also noted that there is significant value to users in maintaining the continuity of the existing RPI’s long time series without major change, so that it may continue to be used for long-term indexation and for index-linked gilts and bonds in accordance with user expectations.

Therefore, while the arithmetic formulation would not be chosen were ONS constructing a new price index, the National Statistician recommended that the formulae used at the elementary aggregate level in the RPI should remain unchanged.

The ONS will, however, develop a new measure of inflation, called RPIJ, which will use a different, better, mathematical formula.

The consumer prices advisory committee, a body which meets around five times a year to advise the ONS on measures of inflation, accepted that the ONS has a responsibility to make sure that there is a level of continuity in the RPI calculations which would be destroyed if there were a change to the formula. But, given the ONS also has a responsibility to compile those statistics "in line with best practice", CPAC concluded that not changing RPI would be "unsuitable".

On the other side, arguing for no change, were 332 of the 406 replies to the public consultation. The ONS said:

The large majority of responses did not address methodological issues but identified the impact that the changes implied… would have for them.

The competing requirements present a tricky path for the ONS to follow, but it does feel like it has picked the wrong option at this point. The job of the statistics agency is surely to produce accurate statistics, rather than statistics which are continually inaccurate in known ways. The fact that RPI is used to decide the value of, amongst other things, index-linked bonds is a reason for it to be correct, not for it to be artificially inflated.

As it stands, the ONS has decided to continue publishing a "measure" of inflation which has an accepted and understood upward bias of 1 per cent a year. It has done this, not because of any real statistical reasoning, but because greater accuracy would be bad for a majority of stakeholders. That seems like a bizarre abdication of its duty.

France’s burkini ban could not come at a worse time

Yet more legislation against veiled women can only further divide an already divided nation.

Since mayor of Cannes David Lisnard banned the full-body burkini from his town’s beaches, as many as 15 French resorts have followed suit. Arguments defending the bans fall into three main categories. First, it is about defending the French state’s secularism (laïcité). Second, that the costume represents a misogynistic doctrine that sees female bodies as shameful. And finally, that the burkini is cited as a threat to public order.

None of these arguments satisfactorily refute the claims of civil rights activists that the bans are fundamentally Islamophobic.

The niceties of laïcité

The Cannes decree explicitly invokes secular values. It prohibits anyone “not dressed in a fashion respectful of laïcité” from accessing public beaches. However, the French state has only banned “ostentatious” religious symbols in schools and for government employees as part of laïcité (the strict separation between the state and religious society). And in public spaces, laïcité claims to respect religious plurality. Indeed, the Laïcité Commission has tweeted that the ban, therefore, “cannot be based upon the principle of laïcité”.

While veils covering the entire face such as the burqa or niqab are illegal, this is not to protect laïcité; it is a security matter. The legal justification is that these clothes make it impossible to identify the person underneath – which is not the case for the burkini.

 

By falling back on laïcité to police Muslim women in this way, the Cannes authorities are fuelling the argument that “fundamentalist secularism” has become a means of excluding Muslims from French society.

Colonial attitudes

Others, such as Laurence Rossignol, the minister for women’s rights, hold that the burkini represents a “profoundly archaic view of a woman’s place in society”, disregarding Muslim women who claim to wear their burkini voluntarily.

This typifies an enduring colonial attitude among many non-Muslim French politicians, who feel entitled to dictate to Muslim women what is in their best interests. Rossignol has in the past compared women who wear headscarves through choice to American “negroes” who supported slavery.

Far from supporting women’s rights, banning the burkini will only leave the women who wear it feeling persecuted. Even those with no choice in the matter are not helped by the ban. This legal measure does nothing to challenge patriarchal authority over female bodies in the home. Instead, it further restricts the lives of veiled women by replacing it with state authority in public.

Open Islamophobia

Supporters of the ban have also claimed that, with racial tensions high after recent terrorist attacks, it is provocative to wear this form of Muslim clothing. Such an argument was made by Pierre-Ange Vivoni, mayor of Sisco in Corsica, when he banned the burkini in his commune. Early reports suggested a violent clash between local residents and non-locals of Moroccan origin was triggered when strangers photographed a burkini-wearing woman in the latter group, which angered her male companions. Vivoni claimed that banning the costume protected the security of local people, including those of North African descent.

Those reports have transpired to be false: none of the women in question were even wearing a burkini at the time of the incident. Nonetheless, the ban has stood in Sisco and elsewhere.

To be “provoked” by the burkini is to be provoked by the visibility of Muslims. Banning it on this basis punishes Muslim women for other people’s prejudice. It also disregards the burkini’s potential to promote social cohesion by giving veiled women access to the same spaces as their non-Muslim compatriots.

Appeals to public order have, occasionally, been openly Islamophobic. Thierry Migoule, head of municipal services in Cannes, claimed that the burkini “refers to an allegiance to terrorist movements”, conveniently ignoring the Muslim victims of recent attacks. Barely a month after Muslims paying their respects to friends and family killed in Nice were racially abused, such comments are both distasteful and irresponsible.

Increased divisions

Feiza Ben Mohammed, spokesperson for the Federation of Southern Muslims, fears that stigmatising Muslims in this way will play into the hands of IS recruiters. That fear seems well-founded: researchers cite a sense of exclusion as a factor behind the radicalisation of a minority of French Muslims. Measures like this can only exacerbate that problem. Indeed, provoking repressive measures against European Muslims to cultivate such a sentiment is part of the IS strategy.

Meanwhile, the day after the incident in Sisco, riot police were needed in nearby Bastia to prevent a 200-strong crowd chanting “this is our home” from entering a neighbourhood with many residents of North African descent. Given the recent warning from France’s head of internal security of the risk of a confrontation between “the extreme right and the Muslim world”, such scenes are equally concerning.

Now more than ever, France needs unity. Yet more legislation against veiled women can only further divide an already divided nation.
