# Jersey’s key inflation measure may soon be unfit for purpose

**In brief:** Jersey’s Chief Statistician has warned that the rental data underpinning the Island’s inflation figures will become unreliable within a couple of years. No budget currently exists to replace it, and a separate programme of legally required statistical reviews has stalled for want of administrative support.

## The data gap at the heart of Jersey’s inflation measure

Private rents account for 10% of Jersey’s Retail Prices Index, making accurate rental data a cornerstone of the Island’s headline inflation figure. Yet the Jersey Evening Post reports that the pool of households Statistics Jersey uses to track those rents has collapsed, falling from around 2,400 in March 2011 to roughly 955 in March this year. Chief Statistician Ian Cope has warned that the trend is set to continue, telling the Corporate Services Scrutiny Panel: “Within a couple of years this source will not be suitable for use in the RPI.”

The current method relies on information about rents paid directly to landlords by Social Security on behalf of Income Support recipients. The pool has shrunk partly because eligibility for Andium social housing has expanded, meaning fewer private tenants are receiving Income Support. In other words, a policy designed to help people into social housing has had the unintended consequence of quietly hollowing out one of the Island’s most important economic datasets.

## Two solutions, one price tag, and no budget

In his submission to the Scrutiny Panel’s review of the proposed Budget for 2027 to 2030, Mr Cope outlined two possible fixes. The first would see the Housing Minister require landlords to notify government of their rents, potentially delivering high-quality data at low cost to Statistics Jersey, though it would place a new administrative burden on all private landlords. The second option would introduce a compulsory quarterly survey, using the rented dwelling licensing scheme to select participants, at a cost of around £100,000 a year.

Neither option is currently funded. “If Statistics Jersey must fund a private rentals survey to provide data for the RPI, we currently don’t have the budget for that,” Mr Cope said plainly. It is a remarkable admission: the Government of Jersey may soon be publishing an inflation figure with a significant component that is, by its own statistician’s assessment, not fit for purpose.

## Wider pressures on Statistics Jersey

The rental data problem is not the only concern Mr Cope raised. He also revealed that a legally required programme of reviews of key statistics has failed to progress because of a lack of administrative support. A request for additional resources to address this was rejected last year, meaning Jersey may be in breach of its own statistical governance obligations.

On a more positive note, Mr Cope said the proposed annual core budget of £1.963 million was sufficient to maintain regular statistical publications and small-scale developments. Funding has also been confirmed for a year-long survey of household income and spending, due to begin next spring, with income distribution statistics expected by the end of 2028. The survey may start around a month later than planned in order to spread costs, which would delay results by the same amount.

## The NSFW Perspective

There is something almost poetic about a government that struggles to measure its own cost of living accurately while simultaneously presiding over one of the most expensive places to rent in the British Isles. The RPI is not a minor bureaucratic curiosity: it feeds into wage negotiations, benefit uprating, and the broader public understanding of whether life in Jersey is becoming more or less affordable. Getting it wrong, or getting it vaguely, is not a trivial matter.

The fact that a request for additional administrative support was rejected last year, leaving legally required statistical reviews in limbo, does rather raise the question of what exactly the Government of Jersey considers a priority. One hundred thousand pounds a year to maintain the integrity of the Island’s inflation data sounds, in the context of a multi-hundred-million-pound budget, rather like the cost of a decent office refurbishment. Whether the Corporate Services Scrutiny Panel will press the Council of Ministers on this is, one suspects, the more interesting question to watch.
