Big Mac Index

For years, the Big Mac Index from the Economist has been a standard of sorts for examining differences in currencies across the world. Well now we have an online, interactive version of the index.

Am I Your Type, Politically Speaking of Course?

Maybe? But thanks to Pew Research, you can see if we align politically. Today’s post comes via Pete, a coworker of mine, and it is basically a survey that works by asking you 23 political questions on topics from big/small government, immigration, climate change, gay rights, defence spending, &c. They crunch some numbers and spit you out on a results page, the image below a crop from the results for your humble author. (For better or worse revealing my political leanings.)

My type

My type

From a survey standpoint, I found it interesting the questions presented only binary responses. In general, I found that I never agreed with either statement entirely and was forced to choose the “closest” response. Since I never see myself on the conservative side of the spectrum, I was surprised to see my “type”, Young Outsiders, coloured with a tint of red. Regardless, I’m still thankful that according to Pew, I am still more in the centre than on the ends as it makes it a lot easier to compromise. I’ve heard that that is an adult thing to do.

By the way, if you want the results of the full survey upon which this quiz was based, you can check out that site here. It’s full of bar charts for those who like the data visualisation.

Where Guns Are Easier to Find Than Knowledge

I loved the title of this piece from the Washington Post that I had to borrow it myself. Of course all credit goes to that particular copywriter. The Washington Post looked at counties and states where gun stores outnumbered museums and libraries. Thankfully my home county has more knowledge than guns. Sadly, the same cannot be said for large areas of the country.

And of note, while Pennsylvania is narrowly more gun than knowledge, the city of Philadelphia ranks second in terms of ratio of libraries/museums to gun stores at 16.93. Only New York City ranked higher.

The Spread of ISIS

ISIS is the main militant group threatening Iraq (and Syria) these days. The New York Times put together a nice graphic showing how in recent years the group has grown ever more violent by launching ever more attacks within Iraq. Of course, the other country of ISIS operations is Syria, where it has been involved in civil war for years now. This creates a battle-hardened group of fighters that is now, thanks to the fall of Mosul and Iraqi banks and military bases, well funded and well equipped.

Understanding the Boston Subway System

Today’s post is the graduate work of Michael Barry and Brian Card of Worcester Polytechnic Institute. The two looked at the available public data of the Massachusetts Bay Transportation Authority (MBTA)—the T to those that know—to better understand the Boston area subway system. Here the subway system refers to the heavy rail lines, i.e. the Blue, Orange, and Red lines.

In short, the piece has a lot to look at that is worth looking at. This particular screenshot is an analysis of the stations across all times on average weekdays and weekends. You can see how in this particular selection, the size of the station markers pulse depending upon the time of day and the number of turnstile entries. Meanwhile the charts to the right show you the density through time of said entries and then compares the average number of turnstiles entries per day. Text beneath the system map to the left provides a short analysis of the data, highlighting work vs. home stations.

Growth of the Common Core Standard

Today’s piece is a timeline-driven piece from the Washington Post. It looks at the success the Gates Foundation has had in pushing its Common Core standards as an educational standard across the country.

Viewing the Economy All at Once

Normally I try to reserve Fridays for the lighter stuff. But yesterday, the New York Times published a really fantastic piece about how the Great Recession changed the American economy through job growth or loss in each sector of the economy. Naturally this sounds very difficult because the American economy is both very large and very diverse.

If you check the piece out, however, you will find that you are offered a guided tour with analysis to provide context to an otherwise jumble of coloured lines. As a bonus, highlighted words in the text bring up small charts showing the actual job growth history for the particular sector. The jumble, however, is also organised along the x and y axes by two important metrics: wages and jobs since the Great Recession. This allows you to see whether low wage jobs have performed better than higher paying and whether either has created more jobs than the other. Line colouration denotes whether a particular sector has grown and recovered, recovered, not recovered, or recession accelerated a previous decline.

Then at the very end is another really great part of the piece. This is a collection of all the small charts arranged by areas of the economy.

Lastly, for those of you who have to work on smaller screens, don’t worry, they made it responsive. Overall, a great piece.

More World Cup Predictions

Earlier this week we looked at how Bloomberg was doing predictions and odds for the World Cup. Today we look at the Economist’s go. It uses something called the probability circle. It lacks the depth of Bloomberg’s piece, but from a design angle does play off the shape of the soccer ball and not in the cheesiest of fashions. Here it actually begins to work in lieu of our familiar bracket system (see every other sports final tournament series I have ever seen). To be fair, the Economist does not actually make any predictions in this, rather, it provides the odds that different teams will make different stages.

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.

Carbon Emissions

President Obama announced new regulations to be enforced by the EPA that aim to reduce carbon emissions. Principally, the expected reduction will come through state-by-state measures to meet new federally mandated targets. Each state will have the ability to find different means of achieving the cuts, e.g. building more solar plants or nuclear plants or implementing cap-and-trade schemes.

Consequently, the New York Times published this interactive graphic that examines the carbon emissions and energy prices of states. The charts default to a highlight of several Northeast states already participating in a cap-and-trade scheme. The top component charts emissions on a per unit of energy over time while the bottom charts the price of energy.
