Brexit: The more educated a city's population, the less likely it was to vote Leave

Oh. Image: Getty.

The latest instalment of our weekly series, in which we use the Centre for Cities’ data tools to crunch some of the numbers on Britain’s cities. 

There are many reasons why someone might have voted for Britain to leave the European Union. Belief in national sovereignty; concerns about immigration; straight up racism.

There are reasons to think, though, the one of the big ones – this is going to be controversial, but it does seem to be true – might be lack of education.

[Brief pause, while I delete my email address from the "contact us" page and build a bunker of some sort.]

Okay, that's not entirely fair. For one thing, we're looking at aggregated, city-wide data here. Cities with (spoilers) more educated populations were less likely to vote leave – but that tells us nothing about the individuals within them.

For another – say it with me – correlation is not causation. The fact that more educated cities were full of remain voters might be because of some entirely unrelated factor, to do with culture or economics or something else I haven't even thought of.

Those caveats out of the way, though, the results on this as pretty clear cut. Here's an interactive map showing the proportion of working-age residents in each city that have NVQ4 level qualifications or above (graduates, basically). Darker dots mean higher numbers:

That doesn't immediately look like any obvious pattern. But look at the cities which make the top 10:

That’s two university cities, Oxford and Cambridge; three Scottish ones (Edinburgh, Aberdeen, Glasgow); Bristol, Cardiff, London, and a couple of the capital's plush commuter towns (Reading and Brighton).

Now look at this chart we published on Monday, showing which cities had the highest votes for Remain. The two aren't directly comparable – ours uses local authority boundaries, not (larger) Primary Urban areas, and we covered fewer cities.


This time, the top 10 includes Oxford and Cambridge; three Scottish cities (Edinbrugh, Aberdeen, Glasgow); Bristol, Cardiff, London and Brighton. Nine cities are in the top 10 on both lists.

(The only substitution, incidentally, is that we've lost Reading for Manchester. My guess is that's because the Manchester local authority has a quite different profile to the Manchester PUA, which includes 10 boroughs instead of one. But I'm guessing.)

Here's a scatter graph, plotting graduate population against Remain vote in the 29 cities that are in both data-sets. Once again, it's worth remembering that these are using quite different boundaries, something you'd expect to have an impact on any correlation.

And yet:

That is a correlation co-efficient of 0.84. Which is really, really high. Even though it's different boundaries, and so yada yada yada.

There could be other factors at work here, and Paul Swinney, the chief economist at the Centre for Cities, has been trying to work out what they might be. (His charts use the "leave", rather than "remain", vote so the correlation runs the other way. Also, where a point is on 0 per cent, that's a lack of data, not a city with no graduates whatsoever or some such.)

Here's Pauls chart plotting graduate populations against the leave vote:

This one is residents without five good GCSEs (the closest we have to a sort of school leaving certificate):

This one is residents in skilled manual occupations:

Lastly, one that's rather less clear, plotting wages against leave vote:

So – income wasn't a huge factor. But education level and type of occupation  were pretty clearly factors in how people voted last Thursday.

Or, to put it another way, it seems a lot like less educated people were more likely to vote Leave.

Please don't write in.

12 things we learned by reading every single National Rail timetable

Some departure boards, yesterday. Image: CC-BY-SA

A couple of weeks ago, someone on Twitter asked CityMetric’s editor about the longest possible UK train journey where the stations are all in progressive alphabetical order. Various people made suggestions, but I was intrigued as to what that definitive answer was. Helpfully, National Rail provides a 3,717 page document containing every single timetable in the country, so I got reading!

(Well, actually I let my computer read the raw data in a file provided by ATOC, the Association of Train Operating Companies. Apparently this ‘requires a good level of computer skills’, so I guess I can put that on my CV now.)

Here’s what I learned:

1) The record for stops in progressive alphabetical order within a single journey is: 10

The winner is the weekday 7.42am Arriva Trains Wales service from Bridgend to Aberdare, which stops at the following stations in sequence:

  • Barry, Barry Docks, Cadoxton, Cardiff Central, Cardiff Queen Street, Cathays, Llandaf, Radyr, Taffs Well, Trefforest

The second longest sequence possible – 8 – overlaps with this. It’s the 22:46pm from Cardiff Central to Treherbert, although at present it’s only scheduled to run from 9-12 April, so you’d better book now to avoid the rush. 

  • Cardiff Central, Cardiff Queen Street, Cathays, Llandaf, Radyr, Taffs Well, Trefforest, Trehafod

Not quite sure what you’ll actually be able to do when you get to Trehafod at half eleven. Maybe the Welsh Mining Experience at Rhondda Heritage Park could arrange a special late night event to celebrate.

Just one of the things that you probably won't be able to see in Trehafod. Image: Wikimedia/FruitMonkey.

There are 15 possible runs of 7 stations. They include:

  • Berwick Upon Tweed, Dunbar, Edinburgh, Haymarket, Inverkeithing, Kirkcaldy, Leuchars
  • Bidston, Birkenhead North, Birkenhead Park, Conway Park, Hamilton Square, James Street, Moorfields
  • Bedford, Flitwick, Harlington, Leagrave, Luton, St Albans City, St Pancras International

There is a chance for a bit of CONTROVERSY with the last one, as you could argue that the final station is actually called London St Pancras. But St Pancras International the ATOC data calls it, so if you disagree you should ring them up and shout very loudly about it, I bet they love it when stuff like that happens.

Alphabetical train journeys not exciting enough for you?

2) The longest sequence of stations with alliterative names: 5

There are two ways to do this:

  • Ladywell, Lewisham, London Bridge, London Waterloo (East), London Charing Cross – a sequence which is the end/beginning of a couple of routes in South East London.
  • Mills Hill, Moston, Manchester Victoria, Manchester Oxford Road, Manchester Piccadilly – from the middle of the Leeds-Manchester Airport route.

There are 20 ways to get a sequence of 4, and 117 for a sequence of 3, but there are no train stations in the UK beginning with Z so shut up you at the back there.

3) The longest sequence of stations with names of increasing length: 7

Two of these:

  • York, Leeds, Batley, Dewsbury, Huddersfield, Manchester Victoria, Manchester Oxford Road
  • Lewes, Glynde, Berwick, Polegate, Eastbourne, Hampden Park, Pevensey & Westham

4) The greatest number of stations you can stop at without changing trains: 50

On a veeeeery slow service that calls at every stop between Crewe and Cardiff Central over the course of 6hr20. Faster, albeit less comprehensive, trains are available.

But if you’re looking for a really long journey, that’s got nothing on:

5) The longest journey you can take on a single National Rail service: 13 hours and 58 minutes.

A sleeper service that leaves Inverness at 7.17pm, and arrives at London Euston at 9.15am the next morning. Curiously, the ATOC data appears to claim that it stops at Wembley European Freight Operations Centre, though sadly the National Rail website makes no mention of this once in a lifetime opportunity.

6) The shortest journey you can take on a National Rail service without getting off en route: 2 minutes.

Starting at Wrexham Central, and taking you all the way to Wrexham General, this service is in place for a few days in the last week of March.

7) The shortest complete journey as the crow flies: 0 miles

Because the origin station is the same as the terminating station, i.e. the journey is on a loop.

8) The longest unbroken journey as the crow flies: 505 miles

Taking you all the way from Aberdeen to Penzance – although opportunities to make it have become rarer. The only direct service in the current timetable departs at 8.20am on Saturday 24 March. It stops at 46 stations and takes 13 hours 20 minutes. Thankfully, a trolley service is available.

9) The shortest station names on the network have just 3 letters

Ash, Ayr, Ely, Lee, Lye, Ore, Par, Rye, Wem, and Wye.

There’s also I.B.M., serving an industrial site formerly owned by the tech firm, but the ATOC data includes those full stops so it's not quite as short. Compute that, Deep Blue, you chess twat.

10) The longest station name has 33 letters excluding spaces

Okay, I cheated on this and Googled it – the ATOC data only has space for 26 characters. But for completeness’ sake: it’s Rhoose Cardiff International Airport, with 33 letters.

No, I’m not counting that other, more infamous Welsh one, because it’s listed in the database as Llanfairpwll, which is what it is actually called.

11) The highest platform number on the National Rail network is 22

Well, the highest platform number at which anything is currently scheduled to stop at, at least.
