A Shrinking Illinois

Last week we looked at the data on Pennsylvania from the US Census Bureau and found the Commonwealth’s population is shifting from west of the Appalachians to the southeast of the state. That got me thinking about Illinois, one of three states to have experienced a decline in population. Is there a similar geographic pattern evident in that state’s data? (Plus, I lived there for eight years, so I am curious how the state evolved over a similar time frame.)

A lot more red in this map…

Well, it turns out the pattern is not so self-evident in Illinois as it is in Pennsylvania. Instead, we see small clusters of light blues across a sea of red. In other words, the population decline is widespread, though not necessarily extreme. However, it is notable that in the far south of the state, Alexander County, home to the city of Cairo, has seen the greatest decline in population since 2010, not just in Illinois, but in the entire United States (in percentage terms).

Unlike Pennsylvania, where the state’s primary city of Philadelphia is growing (albeit slowly), in Illinois the primary city of Chicago has seen its population shrink over the last several years. However, the counties south and west of Cook County have grown. Kendall County, where parts of Aurora and Joliet are located along with growing towns like Oswego and Plano, grew at over 11%.

The state’s other growing counties fall across the state from north to south, east to west. In the south the county containing the eastern suburbs of Carbondale has grown modestly. But for real percentage growth, one should look west towards Monroe County, a southern suburb of St. Louis, Missouri located just across the Mississippi River.

Then in the centre of the state we see growth in McLean and Champaign Counties. The former is home to Bloomington and Normal. While Champaign is home to the eponymous city as well as its neighbour, Urbana.

All in all, the pattern that emerges is that of urban/suburban vs. rural. With some notable exceptions, e.g. Cook County, the only growth in Illinois is in counties that have prominent cities or towns. Meanwhile, rural counties shrink—the aforementioned Alexander most notably.

Game of Thrones Ratings

No spoilers here, so don’t worry.

But Game of Thrones ended last night. And I might be in the minority in that I like the overall ending and direction of the plot. But, I will agree that it would have been better…executed (just a Ned Stark reference) if at least the final two series were full, 10-episode series. As it is, we’re left to ourselves to connect the dots between previous character actions and their current actions. It makes sense, but you have to really think about it. It could have been done better over time. Alas, time was the one thing they did not have.

Anyway, a lot of people think the final series was terrible. And the ratings on IMDB say just that.

Pennsylvania’s Population Shifts

Last month the US Census Bureau published their first batch of 2018 population estimates for states and counties. Pennsylvania is one of those states that is growing, but rather slowly. It will likely lose out to southern and western states in the 2020 census after which House seats will be reapportioned and electoral college votes subtracted.

From 2018 to 2010, the Commonwealth has grown 0.8%. Like I said, not a whole lot. But unlike some states (Illinois), it is at least growing. But Pennsylvania is a very diverse state. It has very rural agricultural communities and then also one of the densest and largest cities in the entire country with the whole lot in between . Where is the growth happening—or not—throughout the state? Fortunately we have county-level data to look at and here we go.

Some definite geographic patterns here…

The most immediate takeaway is that the bulk of the growth is clearly happening in the southeastern part of the state, that is, broadly along the Keystone Corridor, the Amtrak line linking Harrisburg and Philadelphia. It’s also happening up north of Philadelphia into the exurbs and satellite cities.

We see two growth outliers. The one in the centre of the state is Centre County, home to the main campus of Pennsylvania State University. And then we have Butler County in the west, just north of Pittsburgh.

The lightest of reds are the lowest declines, in percentage terms. And those seem to be clustered around Scranton and Pittsburgh, along with the counties surrounding Centre County.

Everywhere else in the state is shrinking and by not insignificant amounts. Of course this data does not say where people are moving to from these counties. Nor does it say why. But come 2020, if the pattern holds, the state will need to take a look at its future planning. (Regional transit spending, I’m looking at you.)

How Does the UK View Their Political Parties?

The United Kingdom crashes out of the European Union on Friday. That means there is no deal to safeguard continuity of trading arrangements, healthcare, air traffic control, security and intelligence deals, &c. Oh, and it will likely wreck the economy. No big deal, Theresa. But what do UK voters think about their leading political parties in this climate? Thankfully Politico is starting to collect some survey data from areas of marginal constituencies, what Americans might call battleground districts, ahead of the eventual next election.

And it turns out the Tories aren’t doing well. Though it’s not like Labour is performing any better, because polling indicates the public sees Corbyn as an even worse leader than Theresa May. But this post is more to talk about the visualisation of the results.

Of course I naturally wonder the perception of the smaller parties like the Liberal Democrats or Change UK (the Independent Group)

The graphics above are a screenshot where blue represents the Conservatives (Tories) and red Labour. The key thing about these results is that the questions were framed around a 0–10 scale. But look at the axes. Everything looks nice and evenly spread, until you realise the maximum on the y-axis is only six. The minimum is two. It gives the wrong impression that things are spread out neatly around the midpoint, which here appears to be four. But what happens if you plot it on a full axis? Well, the awfulness of the parties becomes more readily apparent.

Neither party looks very good here…

Labour might be scoring around a five on Health, but its score is pretty miserable in these other two categories. And don’t worry, the article has more.  But this quick reimagination goes to show you how important placing an axis’ minimum and maximum values can be.

Demanding the Impossible

The key problem in the Brexit deal remains what to do with the Irish border. In essence, the UK faces the same trilemma it has since the beginning. It wants three things it cannot have at the same time: exiting the EU single market and customs union, so it can create a free and independent trade policy; no hard border between Ireland and Northern Ireland, per the Good Friday Agreement that ended the Troubles; and territorial integrity, i.e. no hard border between Northern Ireland and the rest of the UK in the Irish Sea.

Essentially, the UK can choose two of these three options. Below, I have attempted to show how they relate and what the result is once two of the options have been chosen.

Choose two and only two.

Amazon’s Selection for HQ2

Well this week Amazon finally chose not just one city for its HQ2, but two—New York and Washington. Of course Philadelphia had been angling for the site. Alas, it was not to be. So let’s work with that for this Friday post.

Government Officials Using Private Devices

Earlier this week the news broke that President Trump refuses to use his government-issued iPhone for all his communications and prefers his private, unsecured device. This of course means, and reports indicate is happening, that Chinese and Russian intelligence agencies can listen in on his calls.

So how about those private e-mail servers?

Happy Friday, all.

Swedish Election Results

Sweden went to the polls this past weekend and the results are mostly in, with overseas ballots left to be counted. But the results are clear, a stark rise for the nationalist Sweden Democrats, though not as high as some had feared late last week.

Not surprisingly we had the standard parliamentary seat chart, seen below by the BBC. The nice twist this time is the annotations stating the seat change. (More on that later.)

An unnerving amount of yellow
An unnerving amount of yellow

It does a good job of showing the parties and how they are laid out, though I am sometimes more partial to a straight-up bar chart like below at Reuters.

Here the Sweden Democrats are grey.
Here the Sweden Democrats are grey.

However, both do not do a great job in showing what would traditionally be a kingmaker result for Sweden Democrats. When stacked at each end, neither the centre-left bloc, led by the Social Democrats, nor the centre-right, led by the Moderates, are in control of a majority of seats in the Riksdag. Imagine that neutral colour straddling a 50% benchmark line or sitting in the middle of the seats. It makes it far clearer just how pivotal the Sweden Democrats would usually be. Because, usually, Sweden Democrats or parties like it—in the sense of it won a large number of seats—that help the main coalition cross that 50% threshold would have an enormous sway in the next governing coalition. But here, the Sweden Democrats are an anti-immigrant, nationalist party that both the centre-left and centre-right have said with whom they will not enter talks.

Here the Sweden Democrats are brown.
Here the Sweden Democrats are brown.

But graphically, the thing I always find lacking in charts like those above are just how dramatic the rise of the Sweden Democrats has been. And so for that, we have this little piece of mine that complements the two. Because not all members of the coalitions experienced the declines of their major parties, the Social Democrats and the Moderates. In fact, with the exception of the Green Party, all others rose or, in the case of the Liberals, stayed flat. A more thorough defeat would have probably seen the whole of the coalition falling in the number of seats. Unfortunately for Sweden, in this case, the nationalists took the lion share of the seats lost by the top two parties.

Most Liveable Cities Ranking

There is nothing super sophisticated in these charts, but I love them all the same. The Economist Intelligence Unit (EIU) published its rankings of the world’s most liveable cities and this year Vienna knocked off Melbourne for top spot. But what about the rest of the list?

Thankfully the Economist, a related company, put together a graphic highlighting important or noteworthy cities among the entire dataset. It is a wonderful tangle of light grey lines that have select cities highlighted in thicker strokes and brighter colours. Labelling each city would be too tricky at this scale.

I'm okay with the occasional rainbow spaghetti

I’m okay with the occasional rainbow spaghettiThat said about labelling each city, a few years back I worked on a similar top cities in a category datagraphic for Euromonitor International. We took a similar approach and coloured lines by region, but we presented the entire dataset and then complemented it by some additional charts to the side.

These were always fun pieces on which to work
These were always fun pieces on which to work

What is really nice about the Economist piece, however, is that they opted not to show the whole dataset. This could be a business decision, if people want to find where a particular city they could be persuaded to either outright subscribe or otherwise provide contact information in exchange for access to the data. Either way, the result is a piece that has space to provide textual context about why cities rose or fell over the years.

I think I like these types of pieces because there is so much to glean from getting lost in the chart. And this one from the Economist does not disappoint.
