If you believe the predictions, 2011 will be the year when journalists have more access to data than ever before. Of course, much of the data will also be accessible to the public in general but I suspect more people will be exposed to data via journalism than will actively seek it themselves.
And with that comes a responsibility to make sure that journalists present the full picture with a set of data. In other words, add some context. The old phrase about lies, lies and statistics can be true if one set of data is taken in isolation.
Paul Bradshaw touched on this when looking at a story in November which ‘revealed’ that Birmingham had more CCTV cameras than any other council area. Does that mean Birmingham residents are more-watched than people living elsewhere? Paul suggested that if you divide the population of each council area by the number of CCTV cameras, the answer is no.
So the challenge for 2011 isn’t just making use of all the data that’s available, it’s making use of it responsibly, linking data together to come up with a true picture. When the Birmingham Mail ran its Race for a School Place series – which revealed, using data, the competition for places at each school – it provided a table of the number of places and the number of applications – and also a ratio of pupils per place, creating a level playing field for each school.
If journalists don’t do this, then there will be people who do it for them, post publication. Take, for example, the current Northern Ireland Water story. Thousands left without water, and before the crisis is even over the suggestion is that Northern Ireland Water, because it is still a public body, has been deprived of investment compared to areas in England and Wales, where water companies are in the private sector. Sky News ran the following two graphics in a report yesterday:
This appeared to confirm the emerging Conservative Party line that the problem with Northern Ireland Water was that it was a public body. Public bodies = starved of funding.
But it’s also like comparing apples and pears. I suggested this on Twitter and suggested that dividing that investment by the geographical areas served by the England and Wales water companies and the Northern Ireland one would be interesting:
Total spend of £22.3bn divided by (England 130,395sq km + Wales 20,779sq km = 151,174 sq km) =£147,512 spent per sq km in England and Wales
Total spend of £1.1bn divided by 14,160sq km in Northern Ireland = £77,683 per square km in Northern Ireland.
This would suggest that the private sector does put more into its infrastructure work – but is even this figure fair? After all, there will be large parts of England and Wales which have nothing to do with the water companies. What is really needed to make this number fair is a comparison of infrastructure:
This data took 10 minutes to compile. The hardest part was working out how to present a table on WordPress!
So, if we add up the water mains and sewers of Northern Ireland, we have a combined figure of 41,000km. Divide that £1.1bn of spending by 41,000km we have £26,829 spent per km.
If we do the same with the sewers and the mains in England and Wales against the £22.3bn spent in England and Wales we have a figure of £37,305 spent per km.
Is the extra £10,000 spent per km as ‘sexier’ a figure as comparing £22.3bn against £1.1bn? No – but it’s a whole lot more accurate when all things are considered.
And that’s the challenge in 2011 for journalists: The data’s coming, are we ready to use in context and find the stories which still mean something?
