Guerrilla Cartography is running a Kickstarter to raise funds for its third atlas focusing on the basics of survival. Shelter: An Atlas follows Food (2013) and Water (2017), and will collect more than 60 maps exploring the idea of shelter in its various aspects—“from housing and homelessness to animal habitats and even psychological shelters we build around us.” Examples at the link.

Geographer Christopher Winters maps car ownership—or rather the lack thereof—in The Geography of Carfree Households in the United States. In only a few census tract do more than 75 percent of the population go without owning a car. Not surprisingly, most of them are in New York, plus other densely populated cities: “New York has many more such households than any other urban area. It’s the one large place in the United States where only a minority of households have a vehicle available.”
As part of its extensive coverage of the 2020 census, the Washington Post maps the changes in the U.S.’s ethnic/racial makeup, and where it’s been changing.
Writing at The Conversation, geographers Derek Alderman and Joshua Inwood explore African American examples of “counter-mapping,” from maps made by the Black Panthers proposing new police districts to modern interactive maps of lynchings and police violence. “Black Americans were among the earliest purveyors of counter-mapping, deploying this alternative cartography to serve a variety of needs a century ago.” [Osher]

Last year I told you about Charles Booth’s London Poverty Maps, a book collecting and analyzing the maps produced by Booth’s block-by-block survey of poverty and the social classes of late 19th-century London. Somehow I missed the fact that there has been an online, interactive version of said maps for several years now. [Open Culture]

Charles Booth’s London Poverty Maps (Thames & Hudson, October) is a look back at Booth’s idiosyncratic and judgey block-by-block survey of poverty and the social classes of late 19th-century London (his maps described the “lowest class” as “vicious, semi-criminal,” for example). The final maps, hand-coloured, are famous in map terms: there was an exhibition back in 2011. The book adds preparatory maps, “selected reproductions of pages from the original notebooks, containing anecdotes related by Londoners of every trade, class, creed and nationality together with observations by Booth’s interviewers that reveal much about their social class and moral views.” Plus essays and infographics to put the whole thing in a modern context. Mapping London has a review.

Data.Pour.Paris is a collection of interactive maps about the city of Paris. It’s a lot more interesting—and granular—than it appears at first glance, though. The traffic and real-time metro maps you might expect, but the map of street lights drills down to individual streetlights—and their wattage. Public order complaints are mapped individually, and there’s even a map of the 2018 Paris marathon that tracks the progress of individual runners. They’re the work of French engineer Benjamin Tran Dinh, and they’re neat. They speak as much to the availability of such data as the ability to map it. [Maps Mania]

The HTC 2020 map is an interactive map of hard-to-count communities built for campaigns to increase participation in the United States’s 2020 census. Hard-to-count communities are populations that historically have a poor self-response rate: they return their census forms online or by mail at lower rates, requiring followup interviews by enumerators. The map shows response rates by census tract, and notes the demographics of each tract in terms of why the response rates might be low: lack of Internet access, or large numbers of people who are historically undercounted (poor, rural, people of colour).

CBC News: “A group of researchers at the University of Ottawa is using Google Street View to spot instances of gentrification in the city’s neighbourhoods. […] The program looks for patterns of improvements on individual properties, such as new fences, landscaping, siding or significant renovations.” Honestly not something for which I expected Street View to have a use.
Laura Vaughan’s Mapping Society: The Spatial Dimensions of Social Cartography (UCL Press, 3 September) “traces the evolution of social cartography over the past two centuries. In this richly illustrated book, Laura Vaughan examines maps of ethnic or religious difference, poverty, and health inequalities, demonstrating how they not only serve as historical records of social enquiry, but also constitute inscriptions of social patterns that have been etched deeply on the surface of cities.” Available in the U.K. in hardcover (£45) or paperback (£25), but you can also download the PDF for free: the book is published under a Creative Commons licence.
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.
Update: The above is lacking in some detail; here’s the Toronto Star review to make up for it.
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.”
Datawrapper has added population cartograms to its map collections, and in its blog post discusses the advantages and disadvantages of cartograms vs. geographical maps, as well as the advantages and disadvantages of some of the different types of cartograms. Turns out that cartograms are kind of like map projections: each has its pros and cons; each is better suited to some uses than to others. [Caitlin Dempsey]
Maarten Lambrechts discusses how to make a dot density population map, in technical detail. He uses QGIS to process data for his home country of Belgium. The map above is one result (he also zoomed in on Brussels).
