More Election Cartography Primers

Today, print subscribers to the New York Times were treated to a fold-out map showing a choropleth map of the 2012 election results at the ZIP code level (above). “The map is part of a special election section that aims to help explain the political geography of the United States — identifying where people who are conservative and liberal live and pointing out how physical boundaries, like the Rio Grande and the Cascade Mountains, often align with political ones,” writes the Times’s Alicia Parlapiano.
Parlapiano’s piece is in fact a lengthy tutorial on how to read election maps, along the lines of the pages I linked to in last week’s post on election map cartography—it outlines the problems of state-level election maps and choropleth maps that privilege area over population, for example, and shows some other ways of depicting the results.
It can’t be a coincidence that in today’s Washington Post we have Lazaro Gamio’s article dramatically highlighting the difference between area and population size with comparative maps. Mark Newman’s cartograms also make an appearance.
I can only conclude that both the Times and the Post are making efforts to educate their readers before the election results start coming in, one week from tonight. (Deep breath.)
You Are Here: NYC
Today is the publication date for Katharine Harmon’s latest book of map art: You Are Here: NYC: Mapping the Soul of the City (Princeton Architectural Press). This is Harmon’s third map art book and features some two hundred maps of New York City, “charting every inch and facet of the five boroughs, depicting New Yorks of past and present, and a city that never was.” Fast Company Co.Design’s Meg Miller has a piece on the book.

Ricci Map Derivative Found in a Garage Sells for $24,000
Two dark, torn illustrations found in the garage of a Palm Springs home and listed for sale as “two 19th century hand colored prints of the world” turned out to be something quite possibly a bit more significant. First identified as two panels (of six) from a 1708 Korean map, Kim Jin-yeo’s Gonyeomangukjeondo (곤여만국전도), which is a derivative of Matteo Ricci’s famous Kunyu Wanguo Quantu (aka the “Impossible Black Tulip”), the panels ended up selling earlier this month for $24,000; the buyer, map dealer Barry Ruderman, is restoring the map for sale and suspects that it may in fact be a 17th-century Chinese copy rather than a Korean map.

Mount Buggery to Nowhere Else: A Book on Australian Toponyms
A decade ago Mark Monmonier published
Many of Evans’s humorous stories go a way to responding to some of the scientific inadequacies and toponymic foibles so common in place naming studies. And after I’ve spent almost a decade inundated with often sterile and uninspirational place name theory and how it may fit within more general research in onomastics, the study of proper names, Evans’s tongue-in-cheek take is more than welcome.
I get the distinct impression that this is a less-serious work of scholarship than Monmonier’s. [WMS]
Speaking American
Based on an interactive dialect quiz in the New York Times that generated more than 350,000 responses, Josh Katz’s Speaking American: How Y’all, Youse, and You Guys Talk: A Visual Guide “offers a visual atlas of the American vernacular—who says what, and where they say it—revealing the history of our nation, our regions, and our language.” Out now from Houghton Mifflin Harcourt.

Grim London
Here’s an appropriately spooky map for Halloween: Grim London, a map that celebrates the creepy side of London’s history. “Bringing the scary truths to life, Grim London is a personalised interactive map of the most spine-chilling events that have occurred across the capital.” [TimeOut London]
Mapping Obamacare

The New York Times maps the decline in the numbers of the uninsured since the implementation of the Affordable Care Act.
Over all, the gains are substantial: a seven-percentage-point drop in the uninsured rate for adults. But there remain troublesome regional patterns. Many people in the South and the Southwest still don’t have a reliable way to pay for health care, according to the new, detailed numbers from a pair of groups closely tracking enrollment efforts. Those patterns aren’t an accident. As our maps show, many of the places with high uninsured rates had poor coverage before the Affordable Care Act passed. They tend to be states with widespread poverty and limited social safety nets. Look at Mississippi and Texas, for example.
NACIS 2017 in Montreal
Next year’s annual meeting of NACIS, the North American Cartographic Information Society, will take place from 10-13 October 2017 in Montreal. Hey, my home province — I might actually be able to attend.
A Primer on Election Map Cartography
With less than two weeks before the 2016 U.S. presidential election, it’s time for a refresher on election map cartography, particularly in the context of U.S. presidential elections.
Cartograms

Let’s start with the basics: at All Over the Map, Greg Miller explains the problem with U.S. presidential election maps—big states with few electoral votes look more important than smaller states with more votes—and introduces the idea of the cartogram: a map distorted to account for some variable other than land area.
Here are some cartograms of the 2012 U.S. presidential results (see above). Previously: Cartograms for the 2008 U.S. Presidential Election Results.
The Map That Started It All

Back in 2014, Susan Schulten looked at the map that may have started it all: an 1883 choropleth map of the 1880 U.S. presidential results (see above) that shows results not only on a county-by-county basis, but also the amount the winning candidate won by.
The map may not look advanced today, but in 1883 it broke new ground by enabling Americans to visualize the spatial dynamics of political power. Readers responded enthusiastically. One reviewer pointed to the Republican counties in Arkansas—something left invisible on a map of the Electoral College returns—and wondered what other oddities of geography and history might be uncovered when election returns were more systematically measured. In other words, the map revealed spatial patterns and relationships that might otherwise remain hidden, or only known anecdotally. Perhaps its no coincidence that at the same time the two parties began to launch more coordinated, disciplined, nationwide campaigns, creating a system of two-party rule that we have lived with ever since.
(This map also inverts the modern colours for the two main U.S. political parties: here the Democrats are red and the Republicans are blue. Those colours were standardized only fairly recently.) [Geolounge]
Rethinking Election Map Design
Back to Greg Miller, who has a roundup of different kinds of election maps throughout history, including the maps we’ve seen here so far, Andy Woodruff’s value-by-alpha maps (previously) and others.
For other ways of mapping election results, see this gallery of thematic maps, which includes things like 3D choropleth maps, dot density maps, and all kinds of variations on cartograms and choropleth maps. There’s more than one way to map an election. [Andy Woodruff]
5,000-Year-Old Stone Map Found on Danish Island
An archaeological dig on the Danish island of Bornholm has turned up a small stone, in two pieces, with scratches in a criss-cross pattern that has led researchers to conclude it’s a 5,000-year-old map of the island.
Earthquakes, Eruptions and Emissions
The Smithonian’s Earthquakes, Eruptions and Emissions interactive map “is a time-lapse animation of volcanic eruptions and earthquakes since 1960. It also shows volcanic gas emissions (sulfur dioxide, SO2) since 1978 — the first year satellites were available to provide global monitoring of SO2.” [Axis Maps]
Texas Monthly on Smith Map Studio

Texas Monthly has a piece about Christopher Alan Smith, who for the past decade has been creating original maps, mostly of Texas and Texas-related subjects. It’s been his full-time gig since 2008. Smith uses a mixture of pen-and-ink and acrylic paints:
I tend to follow the style of postage stamps and currency. I use a pen-and-ink stipple technique, which is a series of dots that create the illusion of halftones. Cross-hatching is another method, using lines instead of dots. I’ve also started using engraved wood to give the maps a layered, 3-D look. For example, on my Thirteen Colonies map, I illustrated the coastline on two layers of hardboard.

Mapping Mosul

The New York Times is mapping the battle for Mosul on this page; the maps show the changing front lines around the city (see above).
Meanwhile, the Washington Post explains the history of Mosul in five maps.
Mapping Clinton and Trump’s Upside Potential (Whatever That Means)
Earlier this month FiveThirtyEight built a county-by-county model showing where both Hillary Clinton and Donald Trump’s “upside potential” — by which they meant where they would each benefit from the shifts in the electoral landscape. Compared to 2012, Clinton is underperforming with non-college-educated whites and Trump is underperforming with Asians, African-Americans, Latinos and college educated whites.
To get a handle on how these shifts could affect the electoral landscape, we modeled how many of Romney’s votes came from college-educated whites and minorities and how many of Obama’s votes came from non-college-educated whites in each state, county and congressional district. The difference between these two vote totals, shown in the map above, can tell us where Clinton and Trump have the most potential to build on 2012.
The authors went on to game out what that might look like in terms of the electoral vote if one in five voters in those shifting groups switched allegiances.
