Tracking Polls One Week Out

Well the election is next Tuesday, and last Friday and this past weekend was…interesting. So one(ish) week to go, and we are going to turn to a few posts that use data visualisation and graphics to explore topics related to the election.

Today we start with the latest tracking polls, released on Friday. The piece comes from the Washington Post and highlights the closing gap between Clinton and Trump with a sudden spike in Republican candidate support. But what I really like about the piece is the plot below. It displays the 0 axis vertically and plots time with the most recent date at the top. And then support for the various demographics can be filtered by selectable controls above the overall plot.

Of course the really interesting bit is going to be how much this changes in the next seven days. And then what that means for the results when we all wake up on Wednesday morning.

Gerrymandered Districts

Well last night was the debate and it was a doozy. But while I was looking for some graphics capturing the debate itself, I came upon an article over on the Washington Post about gerrymandering. For those that do not know, gerrymandering is when state-level politicians draw the maps for congressional districts to preserve or diminish support for various representatives. And Pennsylvania is one of those states with a lot of oddly shaped districts.

How Similar Are Pennsylvania and Ohio?

At least politically.

According to this piece from FiveThirtyEight, maybe not as much as they used to be. From a data visualisation standpoint, what stuck out at me was this plot of correlations of how similar various states are. Basically, the closer to the number 1, the more similar, the closer to 0, the less.

Turns out they're not so close

I might question the value of placing the numbers within the squares—see what I did there?—because the colours could be used with a legend to indicate the range of similarity. But if this were an interactive piece, it certainly could be done to reveal the number on tap or mouseover.

Anyway, it was interesting to see that among swing states, Pennsylvania is least like Georgia but most like Minnesota. The former, certainly. The latter, who would have guessed, don’t ya know.

Religiousness

Today’s post is about religion. One of the two things you are never supposed to talk about in good company. And since the other is politics and since I cover that here frequently, let’s just go all in, shall we?

FiveThirtyEight has an interesting piece about religious diversity and a corresponding lack of religiousness. From a graphics standpoint, the central piece is this chart below.

What I would love, however, is for the plot to be interactive. It would be great to let people check out their own individual home states and see how they compare to the everyone else.

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.

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.

Philadelphia’s Obesity Problem

Last week Philadelphia became the first large US city to introduce a soda tax. (Berkeley introduced one a few years ago, but is 1/10 the size of Philly.) The Guardian has a really nice write-up on how the tax was sold not on health benefits, but of civic benefits to the education system. But the article made me wonder if somebody had published a map looking at obesity in Philadelphia. Turns out Philadelphia Magazine published an article with just such a map from another source, RTI International. (You can find the full interactive map here.)

The map has three views, one of which allows you to see areas of statistically significant clustering. North and West Philly had some bright red clusters, whereas the western suburbs, in particular along the Main Line have some very cold blues.

World Income

Over the weekend I found myself curious about the notion of a growing global middle class. So I dug up some data from the Pew Research Center and did some analysis. The linked piece here details that analysis.

I go into more detail than just a map. Hopefully you enjoy the piece and find the analysis informative if not useful.

Where Is Pennsyltucky?

So last week I mentioned Pennsyltucky in my blog post about Pennsylvania’s forthcoming importance in the election. And then on Friday I shared a humourous illustrated map of Pennsylvania that led into an article on Pennsyltucky. But where exactly is it?

Luckily for you, I spent a good chunk of my weekend trying to find some data on Pennsylvania and taking a look at it. You can see and read the results over on a separate page of mine.

Two Tales of One City

Dickens is not my favourite, but that felt an appropriate title for today’s piece from the Washington Post on Chicago residents’ opinions on, well, Chicago. Turns out there is a notable demographic split on how residents feel about various things in the city.

Where is Normal America?

Not every graphic information graphic is a sexy chart or map. Sometimes tables communicate the story just as well. Maybe even better. Today’s post comes from FiveThirtyEight, which examined a claim about what places represent “Normal America”. Turns out that when one looks at the data, here age, race, ethnicity, and education, Normal America is found in the eastern half of the country. And it includes some big cities, notably both Philadelphia and Chicago. The whole article is worth a read, as it goes on exploring states representing Normal America and then places that represent 1950s America.

So where is Normal America? New Haven, Connecticut.
