Diagrams of Power, a group exhibition taking place right now at OCAD University’s Onsite Gallery in Toronto, “showcases art and design works using data, diagrams, maps and visualizations as ways of challenging dominant narratives and supporting the resilience of marginalized communities.” Curated by Patricio Dávila, it runs until 29 September. Free admission.
Puerto Ricans, as U.S. citizens, are able to travel freely between Puerto Rico and the U.S. mainland. In the wake of Hurricane Maria, many of them sought refuge in Florida, New York and other parts of the U.S. Using anonymized cell phone location data for some 500,000 smart phones, data analysis firm Teralytics was able to map where Puerto Ricans moved from August 2017 to February 2018. CityLab has the maps and the story: “Between these months, nearly 6 percent of the Puerto Rican population left the island and is still living in the continental U.S. Another 6 percent left between October and September 2017 but returned to the island by February 2018.”
NASA’s Socioeconomic Data and Applications Center (SEDAC) has produced a population estimation service “for estimating population totals and related statistics within a user-defined region.” Basically, it provides a population estimate for an area drawn on a map. Available as data via map and GIS clients, it’s also accessible via a web app. I’ve noodled about with it; its population estimates are generally not insane. [Kottke]
One of the proposals in the new draft London Plan is to prohibit new fast food establishments within 400 metres of an existing school as a means of combatting childhood obesity.1 This is going over about as well as you’d think. Dan Cookson has mapped the locations of London’s fast food establishments and the 400-metre exclusion zones around each school; his map suggests a problem: there would be few places in the city able to host a new fast food joint.
It’s in French, and the accompanying text is weighted toward Quebec examples, but Le Devoir’s interactive map showing neighbourhood-by-neighbourhood median income levels, based on recent census data, and how they relate to the national average is worth looking at even so. [Nathaniel Kelso]
Atlas of Nebraska by J. Clark Archer et al. (Bison Books). “Far more than simply the geography of Nebraska, this atlas explores a myriad of subjects from Native Americans to settlement patterns, agricultural ventures to employment, and voting records to crime rates.” [Amazon]
Update (30 Oct.): Jonathan Land Evans writes with information on overseas orders for his book, Bermuda Maps: “The most direct way by which people overseas may order copies is by e-mailing firstname.lastname@example.org, as the museum now uses The Bookmart bookstore in Bermuda for all order-fulfillment involving shipping to addresses outside Bermuda. The hardback book is a large one, handsomely illustrated in colour, and costs $65 plus postage.”
The Conversation has a piece on how indigenous peoples in the Amazon are using “counter-mapping” to reclaim not only their ancestral lands, but as a way to counter the colonial process of mapmaking itself.
Maps have always been part of the imposition of power over colonised peoples. While map-making might be thought of as “objective”, it is fundamentally political, a necessary part of controlling a territory. Maps inscribe borders, which are then used to include some and exclude others.
During a late 19th-century rubber boom, Amazonia became increasingly well mapped out as the young nations of Peru, Bolivia, Brazil and Colombia vied for territorial control. The rights and interests of Amazonian peoples were never included in this process and they would be continually denied rights, recognition and citizenship from these nations until the 1980s and 1990s. Even following legal recognition, their territorial rights—critical for their continued existence—are still often ignored in practice.
These marginalised people are now working together to reclaim the process of mapping itself. In the central Brazilian Amazon there has been a recent flurry of “counter-mapping”, used by forest peoples to contest the very state maps that initially failed to recognise their ancestral territorial rights.
Along with Regions and Seasons (previously), the Boston Public Library’s Leventhal Map Center is hosting another exhibition, Who We Are: Boston Immigration Then and Now, which runs until 26 August. “This exhibition compares the landscape of today’s ‘new’ Boston with that of over 100 years ago. The maps and graphics on display here show where Boston’s foreign-born residents originate from, and where newer immigrant groups have settled, while celebrating who we are, and the vibrant diversity that is Boston.” Text is in English, Spanish, Haitian Creole, Chinese and Vietnamese.
Statistics Canada released population and dwelling data from the 2016 Census yesterday. MountainMath’s CensusMapper project already has interactive maps based on that data: population change since 2011 (absolute and percentage), population density, and unoccupied dwellings—with presumably more to come, since the interface allows you to make your own census-derived maps.
Oxford geography professor Danny Dorling spoke at the TEDx Exeter conference in April 2016. If you’re familiar with Dorling’s work, it will come as no surprise that he makes extensive use of cartograms to describe the world’s population. Video: TED, YouTube.
Decades after German reunification, there are still stark differences between the former West and East Germany, and every so often those differences are explored and examined. Yesterday marked the 26th anniversary of reunification, for which the Washington Post saw fit to dust off and update a 2014 analysis. There are lots of maps, exploring everything from employment to flu vaccination to camper trailer ownership, but all but one date seem to be from that earlier version. This Post piece draws heavily on a 2014 article from Die Zeit (in English), which has even more interesting maps (with a rather funky design).
