Mass Shootings in the United States

America loves its gun. The big draw of this piece from the Washington Post is the illustration of the guns used in the mass shootings and whether each was legally or illegally acquired. But more interesting from a data visualisation standpoint are the charts below. They show the numbers of killers, victims, and then the demographics of the killers.

How Africa Tweets

Today’s piece is hit and miss. It comes from the World Economic Forum and the subject matter is the use of Twitter across Africa. I think the subject matter is interesting; mobile communication technology is changing Africa drastically. The regional trends shown in the map at the core of the piece are also fascinating. Naturally I am left wondering about why certain countries. Does spending on infrastructure, GDP per capita, disposable income levels have any sort of correlation if even only on a national and not city level?

But what really irks me is the content that wraps around the map. First the donut chart, I think my objections to donuts—at least the non-edible kind—are well known. In this case, I would add—or sprinkle on—that the white gaps between the languages are unnecessary and potentially misleading.

Secondly, the cities are eventually displayed upside down. Thankfully the labels are reversed so that city names are legible. However, the continually changing angle of the chart makes it difficult to compare Douala to Luanda to Alexandria. A neatly organised matrix of small multiples would make the data far clearer to read.

In short, I feel this piece is a good step in the right direction. However, it could do with a few more drafts and revisions.

White Racism in America

Racism is a long-standing problem for humanity. But in the wake of the Donald Sterling scandal in the NBA, the New York Times put together a graphic looking at white attitudes towards blacks in the United States. The data reveals that while racist views are down from highs decades past, there is still a substantial amount.

From a design standpoint, I would have probably added some sort of axis label. Additionally, I would have removed that topmost segment and used the space for the labelling.

Defining the Midwest

Last Friday, we looked at how one individual defined the state of Florida. Today, we look at how FiveThirtyEight attempted to get lots of people to define the Midwest.

Personally, as someone from Philadelphia I tend to side with the author of the article, Walter Hickey. He writes he’s “from New York, and [he] generally consider[s] anything west of Philadelphia the Midwest.” That’s pretty much the truth.

And if you like this piece, check out the subsequent piece on defining the South.

Ukrainian Unity

In the votes held this past weekend, the separatists in Donestk and Luhansk claim they received a mandate for independent states. However, according to polls conducted by Pew a few weeks back, most of Ukraine, with the notable exception of Crimea, wants to remain united as a single country. In fairness, this poll was conducted after Russia annexed Crimea but before the deaths of pro-Russian separatists in Odessa and Mariupol. (Anecdotally, those events have driven some to the separatist camp.) The map below is part of the Pew report. However, I have an issue with it that, again in fairness, might not be solvable given whatever raw data with which Pew was working.

Who wants secession? Only Crimea.

Who wants secession? Only Crimea.

The map colours each oblast, roughly equivalent to a US state, according not to the results of the survey, but rather to which region the oblast belongs. For example, Kirovohrad is the same colour as Donetsk. Donetsk, however, is the epicentre of the unrest in Ukraine whereas I have at least seen no reports of unrest in Kirovohrad. Are they really reporting the same desire of unity or secession? Would the map not be clearer if each oblast was reported independently?

My guess is that results like these are clear to the Kremlin. And so I think while Donetsk and Luhansk will remain Ukrainian, Crimea will likely remain Russian.

Home Ownership

I am pretty much a sucker for small multiples. And so today I present a good one from the Washington Post. The story starts looking at the broad, national scope of the issue. And from there it breaks home ownership down by state.

Linguistic Empires

One of the main arguments used by Vladimir Putin to support any possible intervention in Ukraine is the suppression of the rights of Russian language speakers. The Economist wisely decided to wholeheartedly endorse the underlying principle of Putin’s logic and redrew the world map accordingly. You should read the article.

Indoor Plumbing

Today’s post is a small interactive map—nothing fancy there—about indoor plumbing. As it turns out not every home in the United States has it. Of course, last weekend I ended up driving through those dark counties in western Pennsylvania. And I can believe it. And I can definitely say I saw a few outhouses.

Baseball Nation

Baseball is back. And thankfully the New York Times has mapped out most of Major League Baseball’s fans. The glaring exception is, of course the omission of Canada/Ontario, home to the Toronto Blue Jays. The piece maps the data of Facebook likes down to the zip code and then offers details on a few border regions in particular.

And apparently back home, I am not the only person cheering for Boston.
