I’ve been skirting the edges of the open data move­ment since I started this site. For those not in the know, open data is when govern­ments and big corpor­a­tions release their figures to the world — finan­cial figures, crime figures, bus figures — anything and everything, for people to do what they want with. Some great projects like fixmys­treet have come out of it.

I really believe this data trans­par­ency can help us achieve great things. So I was very happy when I first went to an open data confer­ence and started talking about plain language, as people were very receptive. It’s not just about the data, I tried to say — you have to make sure you’re giving people the right advice about how to inter­pret the data too, and for that you need plain language. Great, they said, then walked away to talk about XML or some other program­ming thing. Why? Well, most of them were program­mers, so that makes sense. And I came to the even­tual conclu­sion that because plain language can’t be programmed — it’s not an ‘easy’ win — people lost interest quickly.

Which is why Alice Bell’s post Making ‘Nullius’ Public really reson­ated with me. Open data is a fant­astic goal, and I whole­heartedly support what its trying to achieve and the lengths the move­ment has gone to, to success­fully court both this govern­ment and the last. But to be really access­ible, and truly usable, it needs sound inter­pret­a­tion and clear communication.

From a (semi-)professional plain language perspective, I believe open data really bene­fits from exposure to experts and inter­preters, and vice versa. Infographics can be a good example of this. However, they are usually built on a direct data-to-interpreter rela­tion­ship, which can lead to mistakes, and if they’re popular, those mistakes can be compounded. The ques­tion for me is does inter­preter alone neces­sarily have all the know­ledge to get to the bottom of an issue? For me, that answer is usually no, and I’m not afraid to admit it.

For example, I really wanted to take part in the latest finan­cial chal­lenge from Information is Beautiful. I looked at the data, examined GDP and debt rela­tion­ships — appar­ently external debt (what we owe other coun­tries) is more important than internal debt for meas­uring finan­cial stability — ranked coun­tries (according to my calcu­la­tions Ethiopia is one of the finan­cially health­iest coun­tries in the world… ahem), examined the data for patterns, but I knew, ulti­mately, that I was missing some­thing too big to make doing the infographic worth my while. My inter­pret­a­tion, whatever it might have turned out to be, would be essen­tially worth­less, because I didn’t have the know­ledge. I didn’t know what the vari­ables were.

In an ideal world, as a graphic and written inter­preter of data, trends and world events, I’d have access to some­thing resem­bling the journ­al­istic process, an inform­a­tion triangle of:

  1. The hard data to provide the bedrock for my argument.
  2. An unbiased expert (or two oppos­itely biased ones, as long as they could legit­im­ately be called experts) on call to fill in the know­ledge gaps that skew my calculations.
  3. My own expertise in commu­nic­ating stories (such as it is).

I feel we would all benefit immeas­ur­ably from a way to reach out to each other: open data special­ists and tech­no­lo­gists; plain language writers and commu­nic­a­tions people; scientific, economic, polit­ical and other experts for help with our issues.

The full version of this Ordnance Survey paper is now up, have a look!

Because you’ve been waiting ages, here’s my over­view of the free maps package the govern­ment are (sort of) offering with every option for Ordnance Survey’s future.

As for the rest, Simply Understand’s kryptonite might well be busi­ness speak. It’s on it’s way. Not proving easy though. Definitely an area I need more exper­i­ence in.

Free mapping data for all?

Back in November the govern­ment said some of Ordnance Survey’s mapping data (also known as geograph­ical inform­a­tion, or GI) would be released for free. Don’t get too excited, because the date hasn’t been set yet, and they’re still not sure how they’re going to afford it.

However, this consulta­tion does talk about what they might be giving out:

This list might change, but there’s poten­tial to add more in the future, too. Ordnance Survey have to main­tain and update the data too.

As you can see, there’s some prob­lems with post­code data. There’s no one data­base with everything in it. There are quite a few post­code data­bases around, and they all do different things. At least two companies are involved too, Royal Mail and the NLPG, and at the moment they want to protect the money they make from their data.

A national post­code database

If we want one national post­code data­base, we need someone in govern­ment to cham­pion the cause and find some solu­tions to prob­lems with how to fund it and main­tain it. Various govern­ment depart­ments are trying to work with everyone and find a solu­tion, but there’s a lot to think about and it needs someone to help drive it.

The idea is to have this map data avail­able under Creative Commons.

How are we going to get to all this data?


There are four ways:

  • Just looking – for the general public, with search, printing and the ability to see the data. Probably no satel­lite images or direc­tions service though.
  • Downloading – select an area of the map and types of inform­a­tion, and save them to your harddrive
  • API – free to access but will prob­ably be limited in some way (perhaps traffic) to keep costs down.
  • Order on DVD, and get charged for the discs, postage and packing.

Ordnance Survey anti­cip­ates these will move with the times as tech­no­logy gets better and faster.

The winners

New busi­ness
All this free data will help people create new, inter­esting and prof­it­able services and products. In Canada a similar scheme has increased map sales quite a lot.

…and losers

  • Ordnance Survey
    This free scheme does mean OS will lose money. It will also cost just under £10m over 5 years to set up the service.
  • Their part­ners
    The people who work with OS and add value to the existing mapping info will have a lot more competition.
  • Competitors
    These are popular products which have some rivals, and we’re setting the cost of these products at £0. Some compet­itors might lose out.
  • Map buyers
    Less maps might get printed, because people are down­loading and printing them instead. If this happens, the govern­ment might support a national series of maps.

There’s more to come, but that ought to keep you all busy!

So, I didn’t win a data visu­al­isa­tion compet­i­tion. Oh well, fair enough — the data set we were given was quite simple — this is how many black students there are applying for univer­sities, and this is how many of them got into Oxford, Cambridge, Durham and UCL.

This was, I felt, the wrong ques­tion. I didn’t just want to track how black people weren’t getting into our top univer­sities. I wanted to see if the (quite obvious) bias really started there. So that’s what I did, using UCAS’s really quite cool stat­ist­ical tool and the quite frankly amazing Neighbourhood Statistics:

Now there aren’t as many black students as there are white in the UK, but to make for easier compar­ison I’ve started them off on an equal footing — conveni­ently ignoring all the social factors which usually mean they don’t. I started with kids who took their GCSEs in 2006, and worked upwards to the latest lot who are just now off to University. Mathematics aren’t my strong suite, however, so please feel free to check I’ve got it right.

So as far as I can tell, as outrageous as it is that black students don’t get into our top univer­sities with quite the ease they should, what’s even more outrageous is that’s despite being slightly ahead of the game the whole way through. Black students got more A*-C GCSE grades than white. At A-level their grades weren’t quite as good as white students but they passed more subjects. A huge percentage of black students actu­ally applied to go to univer­sity compared to white students, but less of them got in — not just to the top univer­sities, but to all universities.

And to crown it all, the black students brave enough to apply to the very top of the University food chain here in the UK, Oxford and Cambridge, were less than twice as likely to get offered a place than if they happened to be white. Well, that’s just plain ridicu­lous, isn’t it?

I’d quite like to get data on the ethnic makeup of the top schools that tend to get accepted and combine the two.
