Tracking the Royal Navy in World War I

I’ve always liked naval history. So I was pleased when several days ago this movie of Royal Navy ship movements during World War I was released. Using data from navigation logs, it plots the locations of the UK’s naval ships throughout the course of the war and so when played out over time you see the changes in those positions. The screen capture below shows just how much the UK depended on guarding the trans-Atlantic convoys. But also note the UK’s operations on rivers deep inside China.

My only complaint is that I could not find a way to slow it down or pause it once it had started.

Absentee Ballots

This graphic comes from a set by the New York Times that looks at absentee and mail-in ballots, which are particularly popular in western states. The representation of the absentee ballot from Minnesota in 2008 is then examined to see which areas were the reasons for discounted ballots.

The Drop in the Unemployment Rate and How to Spin It

On Friday we received the monthly jobs report. And the furore that arose with it. Principally the anger stemmed from right-leaning commentators who believed that the non-partisan Bureau of Labor Statistics, a government agency tasked with collecting data on employment among other metrics, “cooked the books”/ “massaged the figures”/ flat-out lied to show a significant drop in the unemployment rate that could not be attributed to people who had stopped looking for work—a cause of some earlier drops over the last few years. As someone who works with data originally collected from national statistics offices across the world on a daily basis, those claims touched a nerve. But I shall leave that rant for another time.

Instead let’s look at the New York Times piece that quickly followed on the outrage of fools. We can look at and analyse the data in different ways—the origin of the phrase lies, damned lies, and statistics—and surely the Republican and Democratic parties would do just that. They did. This New York Times piece shows how that can be—and was—done. It involves points of reference and context.

First the facts:

The Facts
The Facts

Then how the Democrats spin them:

Spin it from the left…
Spin it from the left…

Finally how the Republicans spin them:

Then spin it from the right.
Then spin it from the right.

But the facts themselves do not lie. 114,000 non-farm jobs were added to payrolls. The unemployment rate fell to 7.8%, the lowest rate since January 2009.

I Gesture Unto Thee…

We are in the home stretch of the presidential campaign and the first of the four debates (three presidential, one vice-presidential) is tonight in Denver, Colorado. Unfortunately debates tend to be less about ideas and more about talking points, gotchas, and zingers. Regardless of the debates’ utility, candidates do not always convey everything they express through words. Sometimes they send a message through their body language. The New York Times looks at a few, what they call, signature gestures used by President Obama and Governor Romney.

The gestures are illustrated and then explained and shown in three examples from the respective candidate’s convention speech. The overall use of the gesture is then indicated in a bar showing how often and when in the speech the gestures were used.

The 47%

This is the year of the percentages. From 99 to 47. Earlier this week, Mother Jones revealed via a secretly recorded dinner Mitt Romney as claiming that he doesn’t care about the 47% of people who do not pay income tax. He probably meant that he doesn’t care about getting their vote rather than caring for them as people, but regardless of his intention his statement did not sound good. This 47% are people who are dependent on government, or as Romney’s vice presidential candidate would say, they are “takers”. But is this true?

The great thing about news stories and infographics is that as time progresses, one has more opportunities to find data to back stories and arguments. The day of the breaking news, CNN published this simple pie donut chart. Crude, but given the breaking news it is effective.

Federal Income Tax Payers

It proves that Romney was correct, that 47% of people do not pay income taxes. But, it also proves that Romney was at best glossing over the details or at worst manipulating the people listening into thinking that 47% of people do not pay taxes. It may be only 0.9% of Americans who do not pay any taxes. Furthermore, retirees and young people often do not earn income with which to pay taxes. If retired senior citizens are “takers”, I suppose Romney does not want the elderly vote so often important to the Republican base.

But news stories evolve and more statistics become available. A few days later, the New York Times published a longer infographic piece, with below a cropping of the overall.

The Tax Burden by Income Group
The Tax Burden by Income Group

It expands upon the nature of the story and breaks down the actual tax burden of the American public. It is far more nuanced that Romney stated back in May (the original recording of the video). The poorest Americans do not pay federal income taxes, they have the Earned Income Tax Credit (EITC) that is designed to deal with poverty, especially amongst families with children. It is, very simply, what one would call a tax credit incentivising work. The poorest Americans, however, still must pay payroll taxes and then state and local taxes. In percentage terms, the poorest Americans pay more to their states and local governments than do the wealthiest Americans, who in turn have the greater burden at the federal level. It is worth noting that many government programmes, local schools for example, are often funded at the state and local level.

The problem with Mitt Romney’s argument on taxes is that he wants to cut taxes at the highest income brackets and cut the social safety net programmes for the lowest brackets. We already have evidence that such policies do not correlate with economic growth. They instead correlate to a worsening gap between the wealthy and the poor. Think the 1920s rather than the 1950s, 60s, and 70s.

Tax policy is worth discussing. It is worth debating. But we should do so on the facts. I cannot recall the politician who spoke these words, but as someone once said, “you are entitled to your own opinion. You are not entitled to your own facts.”

Made in the USA. Exported to Mexico.

We trade a lot with China. Everyone knows that. But people might not realise that both Canada and Mexico are also among our largest trading partners. (I suppose it helps that they are both right next door.) Mexico is the second-largest importer of US goods after Canada. (China is third.) The Washington Post looked at which states are exporting the most to Mexico and what their largest exports happen to be.

Opportunity

Curiosity is not the only rover on Mars, eight years after a 90-day mission, we still have Opportunity rolling around. The Los Angeles Times published this graphic detailing the exploration conducted by Opportunity. This is a map of Opportunity’s section of Mars.

Olympic Medal Ranking

As I wrote about last weekend, one can look at the Olympics rankings in a number of different ways. Even without weighting medal counts, one has to decide whether to rank countries by gold medals (as the IOC does) or by total medals (my personal preference). The New York Times looks at both in an interesting ranking chart.

The piece also lets you account for population.

Surveys of Swing States for the 2012 Presidential Election

The New York Times has been conducting surveys or polls of voters and likely voters in swing states, i.e. the states where the 2012 election will be decided. The nice thing about the piece is that it allows the user to select different sets of demographics through which one can view the questions asked. Furthermore, the user can mouse over the individual bar of a response and see the whole set.

England and Wales: 500k More People Than Expected

Census data fascinates me from a data visualisation perspective; one can look at it so many different ways. Last week I looked at some of the Slovakian census data on the Carpatho-Rusyns that live in the northeastern mountains of Slovakia. But yesterday, the British Office of National Statistics released the results from their census of England and Wales (Scotland reports later and Northern Ireland did so already, yay devolution.) One of the big news stories was that England and Wales had 500,000 more people than had been expected. That doesn’t sound like a lot of people, but to put it roughly into American proportions, that would be like finding that there was a whole new city the size of Chicago somewhere in the United States.

But while many organisations and individuals will certainly be looking at the census data in the coming days, weeks, and months, the ONS released its own interactive application. Basically it looks at the population pyramid for England and Wales from 1911 to 2011, a century’s worth of data. But what makes this different from the GE population pyramids, for example, is the context that the ONS has added that strict data pulls lack.

1921 pyramid

Here in 1921, rolling over a particular cohort reveals the details of those aged 30 in 1921. There is a clear difference between the number of men and women. But why? The text block’s first note details how 700,000 men aged 20–40 died during World War I and thus altered the basic structure of the English and Welsh population.

1951 pyramid

And in 1951 we begin to look at the British baby boom in the post-war era. Again, while the Baby Boom might be expected, the ONS also points out that the NHS, the British National Health Service, had also recently started and was positively affecting life expectancy and the general health of the British public. These are again things that would not likely appear in more data-focused pieces.

But everybody loves to compare things to other things. So, the ONS also released a more data-focused application that allows the user to select two different census geographies and compare them. This is more as one would expect, comparing overlays vs. side-by-side looks at different population pyramids. The example below compares London to Birmingham.
