Today’s map comes from the Texas Tribune out of Austin, Texas. The map displays the location of disposal wells, i.e. the sites where the waste water from fracking and related drilling operations are dumped. Firstly, the map hints that the fracking industry is not spread equally across the state.
But secondly, the map does this through the use of hexagons that represent well density. So at a broad, state-wide view, the user sees almost a traditional choropleth. The difference is that these are not natural or political boundaries but rather data constructs designed to aggregate highly granular data points.
Even nicer, however, is that if you want to see where disposal wells are in your county or town, the map lets you do that too. Because as you zoom in ever closer, the individual wells appear within the hexagons that they colour. It’s a very solid piece of work.
Today’s post comes via my coworker Jonathan and his subscription to National Geographic. The spread below looks at the gap in life expectancy between men and women in the United States. Outliers are highlighted by drawing lines to the counties in question while the same colour scale is used on a smaller map to look at historic data. And of course for those concerned about how the US places amongst its piers on the international stage, a small selection of countries are presented beneath in a dot plot that looks at the differences and averages.
Detroit’s population has fallen drastically while its economy has been all but eviscerated with the near-collapse of the American automotive industry. But it was not always that way. The National Post looks at Detroit over the years, starting in 1950. It’s the mapping and charting out of the decline and fall of what was once a great city.

On Friday Hillary Clinton steps down as Secretary of State to (likely) be replaced by John Kerry whose confirmation votes will (likely) be later this week. One of the big roles for the Secretary of State is to travel abroad and represent the United States. If secretaries go where the US needs to be represented, that would imply that some states are more important for foreign visits. So has there been a shift in priorities in recent years?
In this interactive piece the Washington Post looks at where James Baker, Warren Christopher, Madeline Albright, Colin Powell, Condoleeza Rice, and Hillary Clinton visited during their tenure at Foggy Bottom. The screen shots below only show the maps—there are very useful tables for finding data on trips to specific countries—for Baker and Clinton and comparing the two. The shift from the European/Cold War mentality is quite pronounced.

The New York Times looks at who controlled the redistricting of US congressional seats because of the 2010 census. It then showed an example in North Carolina where Republican control led to the state being less competitive in the past for Democrats. In 2010, Democrats held 7/13 seats in North Carolina. But after the redistricting, in 2012 the Democrats held only 4/13. And all of this is done in a small, compact space. This is a very effective graphic.
Earlier this week, the Office of National Statistics in the United Kingdom released census results for England and Wales. (Northern Ireland and Scotland are reported separately.) England has more people than expected, most likely because of undercounting of immigrants, and Wales is now some three million and counting. There are fewer Christians than expected—and fewer Jedi than I expected—as the ranks of the non-religious grow. But from of course all of this comes a bevy of visualisations. These are but a few, but if anybody finds others worth nothing, please feel free to send them my way.
Straight from the source is a set of interactive mapping applications from ONS that compare 2001 data to 2011 data. As best it can, census districts are compared on a one-to-one basis, but with boundary changes that isn’t always possible. Clicking on district provides one with details about the responses for that area.
Perhaps the one thing missing from these—and it may well owe to the aforementioned boundary changes—is a map of changes to see which areas have been most impacted. Or a map of the results compared to the average to see where the average can be found and where the positive and negative extremes can be found.
An infographic from the Guardian looks at the overall dataset with quite a few maps and then circle-y things. While the large map is the white population in 2011, the remaining maps are before and after comparisons. Again, an interesting look would have been perhaps deviations from the average or of the actual change per district.
I appreciate the impact of the main story, the increasing diversity of England and, to a lesser extent, Wales. London in particular is now minority white. However, I am less keen on the circle-y things and that data could probably have been presented in a clearer, more direct fashion. I am not a fan of red, yellow, and green traffic light colours, but I also recognise that the Guardian is working within their brand on this.
Unfortunately this interactive map of Northern Ireland’s national identity does not quite work for me. I appreciate the toggle between the different response options, however, I find the responses themselves hard to compare. The colours remain the same, but the scales for the results change. For those identifying as Northern Irish, the top value is clearly less than those identifying as either British or Irish. But I would have liked to have seen the scales for British and Irish to closer match. I also find the black background distracting and overwhelming the colours. I wonder how the result would have worked if treated with the above aesthetic.
The BBC took a stab too with a section devoted to the results. Unlike the ONS visualisation above, however, the side-by-side comparison is forced to be smaller with the included text. And when one zooms into a particular district, the map degrades into crude polygons—a particular pet peeve of mine—that would be unrecognisable to someone familiar with the intimate geographic details of their home region. (Yes, simple shapes make the files smaller for overview maps, but when seen up-close, they lose their value by making ugly maps.) Also, the colours and bins in this particular view are not as informative as in the view above.
The BBC, however, did create a small graphic for an article that showed population changes in the districts, alas the colours did not work as well as one would hope.
That’s a lot for people to digest, but, overall I think the clearest visualisations go to the ONS. They lack the commentary that can be brought by journalism organisations, e.g. the BBC, but one needs a clear and powerful visualisation before one can start writing an analysis.

Hurricane Sandy hit the Jersey shore before moving northwest through southeastern Pennsylvania. These were two maps from two different electric utility companies providing information on the number of outages. This first and smaller graphic is from PECO. The second and larger is from FirstEnergy. The graphic from FirstEnergy breaks into the township level when zoomed in sufficiently. Clearly from being able to post this, I am among the fortunate with my electricity still up and running.
Clearly these are not all outages, only the outages reported by these two electrical utilities. At the time of writing some 1.3 million people were without electricity in Pennsylvania and over 7 million in the Northeast while Sandy—now an extra-tropical low pressure system—continues to dump rain and snow on the interior reaches of the area.
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.

So perhaps the title is a bit of a non-sequitor, but the Washington Post released a table of the Top-100 counties by average income. As a Washington paper their focus was on that city’s suburbs, three counties of which are Numbers 1, 2, and 3. But I wanted to get a sense of where other counties were, including that of my hometown.
Over the last week a video clip on YouTube that mocked the Muslim prophet Mohammad sparked unrest across the Muslim world, from Morocco to Bangladesh and from Turkey to Kenya. While most of the protests were peaceful, a few were not. In Libya, the US consulate in Benghazi was attacked—in circumstances still not entirely clear—and four Americans were killed, including the US ambassador, Christopher Stevens. In Khartoum, Sudan, the embassies of the US, the United Kingdom, and Germany were all attacked. While in Afghanistan, the Taliban successfully attacked the UK’s heavily fortified base of Camp Bastion, nearest to Kandahar, killing two US Marines and destroying six Harrier jets.
Combing through several news sites, including the BBC, AP, and Reuters among others, I mapped where protests occurred and sought to show how much of that country’s population identifies as Muslim. Most nations were, not surprisingly, heavily Muslim. But several countries with rather small Muslim populations such as Kenya, Sri Lanka, and India also hosted protests, some violent. Not included, because of the difficulty in changing the map, is Australia. Sydney experienced protests nearing rioting as protestors marched.
