Education Correlates to Leave

So this isn’t quite a shocker, but the BBC gained access to more granular Brexit vote data, and then examined the results against demographic data. The conclusion, a lower education level best corresponded to voting to leave the European Union. Again, we all sort of knew that, but this provides an even larger, richer sample size.

Still a sad result

What is interesting from the American perspective is how that compares with the election of Donald Trump. In that case as well, lower levels of education correlated well with votes for Trump.

Of course now I will be closely following the elections in the Netherlands, France, and Germany this year to see if the same lower education level corresponds to the vote in favour of populist, nationalist political parties, e.g. Marine le Pen and Geert Wilders.

Piece, Larsen C

When I was in high school in 2002, it was big news when one of the three Larsen ice shelves in Antarctica, Larsen B, collapsed. And then when I was at university, the band British Sea Power wrote a song titled “Oh Larsen B” that I have always enjoyed.

Now Larsen B was not the first Larsen ice shelf to collapse. That dubious honour belongs to Larsen A, which collapsed in 1995. But, Larsen B will not be the last as the third, Larsen C, is now on the verge of collapse. This graphic from Adrian Luckman, reproduced by the BBC, illustrates how the rift calving the shelf has seen accelerated growth recently.

I believe the colours could have been designed a bit better to show more of the acceleration. The purple fades too far into the background and the yellow stands out too much. I would be curious if the data existed to create a chart showing the acceleration.

The inclusion of the map of Wales works well for showing the scale, especially for British audiences. In other words, an iceberg 1/4 the size of Wales will be released into the Southern Ocean. For those not well versed in British geography, that means an iceberg larger than the size of Delaware. That’s a big iceberg.

When America Votes by Goat

Last week Twitter went a wee bit crazy when Donald Trump’s son posted an image about how the Republican nominee had gained ground. Except that it turns out the image was from FiveThirtyEight and looked only at a demographic split by gender—it was what the map would look if only men voted. Suffice it to say, yeah, the Twitterverse went a wee bit crazy. Thankfully the BBC put together this really great recap with some of the best of it.

Happy Friday, all.

The Shrinking Extent of ISIS

Yes, ISIS does receive a lot of attention in the media and during the presidential debates. But you might be surprised to learn that actually the organisation has lost a significant amount of territory lately. This BBC article details the territorial changes through a nice interactive map slider.

You could create a single map showing the losses/gains instead of using this light-duty interactive piece. And to the BBC’s credit they did. However, between the image quality and territorial changes, I think in this instance the interactive piece does add clarity to the story.

UK Performance at the Olympics

The Olympics are over and Team GB did rather well, coming in second in the medals table with 27 gold medals, more than they won back in 2012 when they hosted the Olympics. (See my piece four years ago where a colleague of mine and I accurately predicted the UK’s total medal count.)

Consequently the BBC put together an article with several data-driven graphics exploring the performance and underpinnings of Team GB. This screenshot captures a ranking chart that generally works well.

However, the use of the numbers within the dots is redundant and distracting. A better decision would have been to label the lines and let the eye follow the movement of the lines. A good decision, however, was to label the grey lines for those countries entering and falling out of the Top-5.

Airplanes in Hangars

Today’s post features a simple set of graphics on the BBC, however the creators were actually the Asia Maritime Transparency Initiative. The background? The increasingly tense geopolitical situation in the South China Sea, where China claims numerous islands and reefs claimed by other countries—and to a smaller extent other countries make similar such claims. Just a few weeks back, the Hague ruled against Chinese claims against islands within the Philippines territorial waters. But as these graphics show, it takes more than a legal decision to effect change on the ground.

Satellite photography shows military installations on numerous Chinese-held islands. But what makes the images potent in the communicative sense is the simple overlay of white plane illustrations. They show how many fighter jets, support aircraft, patrol aircraft, &c. that China can base at the various military installations. It is a simple but incredibly effective touch.

Timeline of Recent French Terrorism Attacks

Yesterday the French Catholic community of Rouen was attacked by an alleged IS terror group. In the aftermath the BBC put together a graphic published inside a broader piece. The graphic documented the recent history of terror attacks in France.

When you read or scroll through the overall piece, a bit more symmetry could be added by aligning dates to the central column. That would make the dates more easily comparable. Though it should be noted the important point is made by the rapid clustering of events in the most recent time period.

And for a personal quibble, I believe that timelines are more effective when the most recent date is at the top. Presume the timeline starts in the 1950s during the middle of the Algerian War fought between France and Algeria, which at the time was an integral part of France. Would we want to read all those incidents from the 1950s and 60s? Likely no. Instead, we could scroll down the entirety of the piece. Here, however, we start in the relative calm of 2012, 2013, and early 2014.

National Heights

And by this title I am not referencing McKinleys, K2s, or Everests. No, the BBC published this piece on the changing average heights of citizens of various countries. This was the graphic they used from the report’s author.

National heights of people
National heights of people

Personally speaking, I do not care for the graphic. It is unclear and puts undue emphasis on the 1914 figure by placing the illustration in the foreground as well as in the darkest colour. I took a thirty-minute stab at re-designing the graphic and have this to offer.

While I admit that it is far from the sexiest graphic, I think it does a better job of showing the growth than decline of national heights by each sex in each of these three select countries. Plus, we have the advantage of not needing to account for the flag emblems. Note how the black bars of Egypt disappear into the black illustration of the person.

In Putin’s Russia Steroids Dope You

I mean really, given the rampant and pervasive nature of the Russian state-aided doping programme, how could I not use the Russian reversal? Yesterday WADA, the international anti-doping agency, released its findings on Russian doping at the Olympics. And, suffice it to say, the report is rather damning. The BBC published this graphic in an article to help demonstrate the scheme.

How it all worked
How it all worked

Unlike the evidence of doping, I find the graphic itself lacking. More could have been done to create more consistent type. Text justification ranges (pun intended) from left to right, without any clear system. Why do some stages, e.g. four, align to the right and then others, e.g. seven, align to the left?

Also, I believe more could have been done with the illustrations, in particular the bottles labelled A and B, to better differentiate between a clean sample and a contaminated sample. Why, for instance, does Step 1 include both an A and a B when it mentions only one sample?

In short, the story certainly warrants explanatory graphics, especially as to how the sealed lids were removed, but this piece is not the solution (pun also intended).

Critiquing Brexit Results Designs: Part 2

So now it is two weeks since the Brexit vote. Yesterday, I looked at the results designs from the New York Times. Today I want to take a look at those of the BBC. Not surprisingly the two share in the use of choropleth maps; the choice makes a lot of sense. People vote within districts and those form the most granular unit of data available. But, whereas the New York Times led and really focused on one giant map, the BBC opted to use multiple, smaller maps. (They did choose a different page for their live results, but we are comparing post-result coverage.) For example, their piece leads in with a map of Leave’s results share.

Leave's share
Leave’s share

There are a few key differences between this and the New York Times. First and foremost, this map is interactive. Mousing over various districts provides you the name, and by clicking you move into a zoomed-in view of the district. It displays the district name, the vote totals and share for the two camps, and then voter turnout. From a design standpoint, the problem with the zooming in is that the scales of the outlining stroke does not change.

Zoomed in, looking at central London
Zoomed in, looking at central London

A thin stroke at the national, zoomed-out view, translates to a thick, clunky, and awkward-looking outline at the local, zoomed-in view. And as the above screenshot highlights, many of the urban districts are small in comparison to the more rural districts. Unfortunately the map does not offer the functionality of zooming-in prior to selecting a district. So many of the districts in the more urban areas like London, Manchester, Birmingham, and Belfast are difficult to see and select. Thankfully, below the map the BBC offers a function to type in your district, post code, or Northern Irish constituency to help you find smaller districts.

Another design criticism I have with the piece is the colour palette. Broadly speaking, the piece uses blue and yellow. The two colours make sense in a few ways. Both are present on the European Union flag, with yellow stars on a blue field. (Importantly the twelve stars do not represent EU members like the US flag’s fifty stars represent the states.) Another, far looser interpretation could be the blue of the Conservatives and the yellow closer to the gold of the UK’s Liberal Democrats, the former broadly anti-EU and the latter pro-EU. Regardless of the rationale, the choice of yellow to display multiple levels of data is less than stellar (pun intended), as this Remain share map highlights.

Remain's share
Remain’s share

Having multiple tints and shades of yellow makes the map difficult to read. The lowest value yellow is brighter than the next higher level, and so stands out more vividly on the map than those districts that had a higher share of Remain votes. Using yellow against blue does work, especially in the bar charts throughout the piece and seen in the aforementioned Islington screenshot. But, as a colour for wider, more intense use, yellow was not the wisest decision.

The BBC also included several other choropleth maps exploring the vote breakdown. In this instance of voter turnout, we have the same choropleth map, but a green colour indicating the total vote turnout.

The colour and its choice makes broad sense; green is what one gets when they mix yellow and blue, when you combine Remain and Leave. However, the map functionality of clicking to reveal results still shows the overall results.

Should the vote results be given the highest priority?
Should the vote results be given the highest priority?

At this point, we have moved on from the vote results themselves to the breakdown of the vote. I would have redesigned the mouse-click to display a results view that highlighted turnout over the results themselves. Certainly keeping the results is important, but the focus of this map is not the vote, but the turnout. The data display should be designed to keep that consistent.

One part of the piece where I quibble with the designer selection of chart type follows on from turnout: a comparison of turnout to the youth population.

The turnout vs the youth
The turnout vs the youth

Asking people to compare undistinguished districts on one map to those of another—note the white district lines have here disappeared—is difficult. My first thought: I would have instead opted for an interactive scatterplot. Comparing the turnout on one axis and youth on the other, the user would have an easier time identifying any correlations or clusters of data.

In contrast, the following map comparison would not work via a scatterplot. Here we compare June’s results to those of a vote in 1975. In the intervening years, the geography of the voting districts changed, and so a one-to-one comparison is impossible.

1975 vs. 2016
1975 vs. 2016

The broad scope, however, is clear. A resounding vote to stay part of the European Market or single market in 1975 evolved into a narrow but decisive vote to leave the European Union in 2016.

The piece then closes out with an interactive map of the total results and then, importantly, a long list of bar charts showing each district’s results. Unlike the map, however, the bar charts are a static graphic. And with a few hundred to view, it becomes difficult to isolate and compare two in particular. But the selection of the visualisation type makes a user’s comparison far more precise.

Overall, I would rate the piece a solid work, but with some clear areas of improvement. And who knows? Maybe there will be a second referendum. Or a new general election. And in that case, the BBC could improve upon the designs herein.
