The birth of a zombie statistic

"Record numbers of people in work" is a meaningless fact.

The Daily Telegraph's Jeff Randall has a triumphalist opinion piece today, proclaiming that, contrary to the claims of "Armageddonistas" (who apparently count amongst their numbers our own David Blanchflower):

The British economy’s most recent data show that we’ve just experienced the fastest quarterly growth in five years, employment is going up, unemployment is coming down, public-sector borrowing is falling; pay in both the public and private sectors is rising, inflation is fading (though still above target), retail sales are positive, as are new car registrations.

Many of the counter-arguments to Randall are a question of framing, and some of the straw men he attacks aren't worth defending.

So while we've experienced the fastest quarterly growth in five years, we've also experienced annual growth of exactly zero per cent; and the ONS explicitly stated in the press conference accompanying the figures that the quarterly fluctuations mean that looking at the longer-term is more accurate.

Similarly, pay in the public and private sector is indeed rising, as it has been for three years. But real pay – pay deflated by inflation – has been negative for years. August, the latest month data for which data is available, saw a 2.3 per cent rise in wages for the whole economy, and a CPI rate of 2.5 per cent. So while the average worker had more pounds in their payslip, they still got 0.2 per cent poorer. And even that nominal pay increase was a high point – in the last year, nominal weekly earnings have risen by above 2 per cent just three times.

(I also can't let it pass that in the same piece in which Randall attacks Blanchflower for "abusing those who challenge his view that fear of inflation is overblown", he also argues that the Armageddonistas are wrong because "inflation is fading".)

Beneath the bluster and legitimate disagreements in which to focus on – for it is just a disagreement as to whether to look at this quarter or this year, or whether falling unemployment is enough to offset falling real wages – is one very concerning use of an outright misleading statistic.

We hoped it would be confined to Prime Minister's Questions and the DWP's perennially dodgy press releases, but Randall's repetition of the "record" 29.59 million in work means that this bears spelling out: the only record is how many people there are in the UK.

Population is at since 1960. This employment statistic has only been counted since 1971. If you look at the employment rate, which is 71.3 per cent, then it is at a high since just 2009. Which isn't much of a record at all.

Of course, it may be that Randall is – against the grain for the Telegraph – cheering the economic benefits of well-managed migration into the UK, which has allowed the economy to grow far larger than it would have with closed borders, and is decrying the "lump of labour" fallacy so commonly applied by his fellow columnists.

That may be the case. Probably not, though.

The deafening killer - why noise will be the next great pollution scandal

A growing body of evidence shows that noise can have serious health impacts too. 

Our cities are being poisoned by a toxin that surrounds us day and night. It eats away at our brains, hurts our hearts, clutches at our sleep, and gnaws at the quality of our daily lives.

Hardly a silent killer, it gets short shrift compared to the well-publicised terrors of air pollution and sugars food. It is the dull, thumping, stultifying drum-beat of perpetual noise.

The score that accompanies city life is brutal and constant. It disrupts the everyday: The coffee break ruined by the screech of a line of double decker buses braking at the lights. The lawyer’s conference call broken by drilling as she makes her way to the office. The writer’s struggle to find a quiet corner to pen his latest article.

For city-dwellers, it’s all-consuming and impossible to avoid. Construction, traffic, the whirring of machinery, the neighbour’s stereo. Even at home, the beeps and buzzes made by washing machines, fridges, and phones all serve to distract and unsettle.

But the never-ending noisiness of city life is far more than a problem of aesthetics. A growing body of evidence shows that noise can have serious health impacts too. Recent studies have linked noise pollution to hearing loss, sleep deprivation, hypertension, heart disease, brain development, and even increased risk of dementia.

One research team compared families living on different stories of the same building in Manhattan to isolate the impact of noise on health and education. They found children in lower, noisier floors were worse at reading than their higher-up peers, an effect that was most pronounced for children who had lived in the building for longest.

Those studies have been replicated for the impact of aircraft noise with similar results. Not only does noise cause higher blood pressure and worsens quality of sleep, it also stymies pupils trying to concentrate in class.

As with many forms of pollution, the poorest are typically the hardest hit. The worst-off in any city often live by busy roads in poorly-insulated houses or flats, cheek by jowl with packed-in neighbours.

The US Department of Transport recently mapped road and aircraft noise across the United States. Predictably, the loudest areas overlapped with some of the country’s most deprived. Those included the south side of Atlanta and the lowest-income areas of LA and Seattle.

Yet as noise pollution grows in line with road and air traffic and rising urban density, public policy has turned a blind eye.

Council noise response services, formally a 24-hour defence against neighbourly disputes, have fallen victim to local government cuts. Decisions on airport expansion and road development pay scant regard to their audible impact. Political platforms remain silent on the loudest poison.

This is odd at a time when we have never had more tools at our disposal to deal with the issue. Electric Vehicles are practically noise-less, yet noise rarely features in the arguments for their adoption. Just replacing today’s bus fleet would transform city centres; doing the same for taxis and trucks would amount to a revolution.

Vehicles are just the start. Millions were spent on a programme of “Warm Homes”; what about “Quiet Homes”? How did we value the noise impact in the decision to build a third runway at Heathrow, and how do we compensate people now that it’s going ahead?

Construction is a major driver of decibels. Should builders compensate “noise victims” for over-drilling? Or could regulation push equipment manufacturers to find new ways to dampen the sound of their kit?

Of course, none of this addresses the noise pollution we impose on ourselves. The bars and clubs we choose to visit or the music we stick in our ears. Whether pumping dance tracks in spin classes or indie rock in trendy coffee shops, people’s desire to compensate for bad noise out there by playing louder noise in here is hard to control for.

The Clean Air Act of 1956 heralded a new era of city life, one where smog and grime gave way to clear skies and clearer lungs. That fight still goes on today.

But some day, we will turn our attention to our clogged-up airwaves. The decibels will fall. #Twitter will give way to twitter. And every now and again, as we step from our homes into city life, we may just hear the sweetest sound of all. Silence.
