21st Century Prohibition

This map comes from the BBC, which investigates prohibition in the 21st century at the local level, as the national policy ended in the early decades of the 20th century.

Heritage Maps

From FlowingData comes a post to an interactive piece by Bloomberg that looks at the geographic distribution of different heritage—read heritage, neither race nor ethnicity—groups. (Its choice of groups, however, is slightly contentious as it omits several important ones, including African-Americans.)

I would say that a typical map like this would simply plot the percent of each county, state, or other sub-division for the selected heritage group. Much like below, as I chose the Irish.

Bloomberg’s piece is a bit more interesting than that because of the ability to compare two groups, to see where they overlap and where they diverge. In doing so, they created a divergent choropleth that can show the subtleties and nuances of settlement patterns.

Bringing 19th Century Mapping Techniques to the 21st Century

Charles Booth was a 19th century social scientist living in Britain. He famously investigated poverty and mapped out which parts of London were teeming with vicious, lower-class criminals or well-to-do upper class folks. Today, one might use a simple choropleth style to paint whole swathes of London by postal districts or constituencies or some such. But, Booth went street-by-street and house-by-house colouring blocks of London’s residential areas until he arrived at a map far more complex—and thus ultimately more telling—of the intricacies of London’s social structure.

Oliver O’Brien has created a modern take on Booth’s approach to investigate the housing demographics of the UK, which ignores the large areas of the British countryside that are devoid of homes and thus focuses on the denser residential areas of the UK’s major cities.

Censuses seem to be a natural dataset for such work, but I wonder if in the future we will be able to apply such data visualisations to other geographically-tied data.

Busting Bunkers

There is quite a lot of talk these days about the possibility of Israel, either with or without American assistance, launching an attack on Iran to halt the further development of its nuclear programme. The trouble is that Israel may not have the weapons necessary to carry out a successful attack, but the US has quite the arsenal. And one of the most useful, for just such a task is the Massive Ordnance Penetrator.

The National Post created an infographic to look at the bomb and just how it might be used if the US should decide to use it.

Delivery Routes

Sunday in the New York Times, an article on bicycle delivery had an accompanying infographic. It detailed the dinner route of the article’s main individual. The piece is an interesting use of small multiples to provide a timeline of a route, while each new delivery maintains the old paths for reference. And from a data perspective, I found it good to acknowledge the one instant where the follower lost contact with the delivery man.

Fatal Passenger Train Derailment

Sunday afternoon in Burlington, Canada, a VIA passenger train—think Canada’s version of Amtrak—derailed shortly after switching tracks. The two engineers in the locomotive and their trainee died in the accident, which is still under investigation.

The National Post covered the story and included a few graphics to explain just what happened. Maps pointed out exactly where the train derailed. The graphic below details how a switch works for those unfamiliar with rail transport.

And lastly, a larger graphic attempts to explain what may have happened in lieu of the final accident report from the Canadian Transportation Safety Board.

And the Award Comes From…an Old White Male. Most Likely.

So apparently last night actors, directors, and others associated with the production of films won little statues. (And then probably celebrated with fancy foods and wines.) Yes, last night was the Academy Awards. But who is this Academy that decides upon the best films and performances?

As it turns out, the demographics of the Academy do not quite mirror those of the broader country. Just over a week ago, the Los Angeles Times looked at the Academy and visualised its membership, discovering the details of which was itself a journalistic feat.

After a broad overview with pie charts and such, each branch was mapped as a choropleth to the Los Angeles area. Those members from outside the LA metropolitan area were given small squares to represent their cities.

As someone not at all familiar with Los Angeles and its neighbourhoods, perhaps where the members of the various branches of the Academy live is actually somewhat interesting. However, I fail to understand the value in that. More useful is the idea of breaking out a socio-economic demographic and mapping that data. And if that had been the case here we almost have a set of small multiples. These are just a bit big.

Overall, a solid body of work.

Tsunami Debris

We are coming upon the date when a year ago an earthquake and its subsequent tsunami devastated Japan. As the wave rushed over land it ripped up and destroyed whole villages. Most of the debris remained scattered across the Japanese landscape, but as the water receded some was inevitably swept back out to sea.

The International Pacific Research Center has released a model of where any floating debris—a good amount is presumed to have sank by now—may have been carried by the ocean’s currents.

What Philadelphians Think About Philadelphia

Yo, Philly, apparently Pew did a survey on what Philadelphians think about Philadelphia. And what better way to talk about a survey than through an infographic. So thanks to the Inquirer, that is what we have.

The interesting bit is that while there is a black-and-white, presumably print version, the website broke the whole graphic into its components and made them larger for web viewing. But, if you look at this example from the segment on immigration and diversity, they ought to have left colour alone. The two segments Bad Thing and No Difference use the same colour when they clearly do not mean the same thing. The black-and-white version keeps those two as separate greys.
