Four coauthors, but no one bothered to add links or a bibliography for the whopping two studies they reference? I wouldn't be so quick to throw stones about improperly citing the literature! @tkemeny.bsky.social @maxbuchholz.bsky.social
Excerpt from Storper et al 2025 (https://www.planningreport.com/2025/07/25/storper-et-al-yes-yimby-ism-profoundly-conservative-and-wrong-housing-policy) critique of Davis 2025 (https://www.theatlantic.com/ideas/archive/2025/07/housing-abundance-antitrust/683504/). The authors criticize Davis for not properly referencing the literature; later in the same paragraph, they cite two studies without linking to the original papers or including a bibliography below. By comparison, Davis properly cites 11 sources in his original op-ed.

Not enough people know about this chart, showing one of humanity's greatest achievements and one of our largest unfinished challenges — made much worse by the dismantling of USAID. ourworldindata.org/child-mortal...
Child mortality rate by country income group from 1990 through 2023. The share of children who died before age 5 in low-income countries declined from nearly 20% in 1990 to 6% in 2023.

Seeing Pike Place chock-full of people this afternoon, it's hard to believe that most of the outdoor market space used to be reserved for cars!
People walking on Pike Place on a sunny day. The street still has a barrier up due to construction: about two-thirds of this street section used to be reserved for vehicles. People are walking on both sides of the barrier, and sone people on the left side of the street are buying flowers from market stalls.

I made an interactive map comparing five minute walks to transit stops (green) with Seattle's plans to allow more housing (brown/orange).

𝗡𝗲𝘄 𝗿𝗲𝘀𝗲𝗮𝗿𝗰𝗵: Published this morning in the Journal of the International AIDS Society, Tram et al. estimate that a 90-day pause in PEPFAR funding will lead to nearly 110,000 excess HIV deaths due to missed ART treatments.

Open access article here: doi.org/10.1002/jia2...
Table 1 from Tram et al. (2025) showing estimated excess HIV-related deaths from a pause in PEPFAR funding, broken down across countries served by PEPFAR. Across all countries, the authors estimate 109,552 excess HIV deaths from a 90-day pause in PEPFAR funding.

Spent a bunch of time making a map for Seattle's Comp Plan comments this evening, waited my turn to speak for 6 hours, and then the meeting got cut short. Sometimes that's just the way the weather goes! I'll look forward to discussing Frequent Transit Corridors with City Council sometime soon.
Photo of me holding a map showing the "Frequent Transit Corridor" along Lake City Way south of NE 100th St. Blue parcels are a short walk to public transit, yellow parcels are zoned multifamily or commercial in OPCD's draft zoning maps. The takeaway: capacity could be added to the blue zones, shifting new residents onto quieter side streets and creating little walkable neighborhoods all around the city!

If Seattle creates one new neighborhood center, it should be in Madrona:
- Madrona is surprisingly amenity-dense for its size
- Madrona's black population dropped by 2/3rds from 2000 to '20. Housing stock may be the same, but "neighborhood character" (who gets to live there) has changed dramatically
Map of Madrona and surrounding areas showing walking times to six amenity types: supermarkets, libraries, parks >1 acre, public transit stops, restaurants, and coffee shops. Most of Madrona is less than 15 minutes from all six of these amenities, and central Madrona is less than 10 minutes from all amenities. A Grocery Outlet is located at MLK and Union, and a public library is located at 33rd and Union along with an elementary school. The map was exported from https://close.city A map showing the proportion of black residents across each block in Madrona as of the 2000 Census. Many blocks west of 34th Avenue were 40% black or greater in 2000. Black residents made up 29% of Madrona's overall neighborhood population in 2000. A map showing the proportion of black residents across each block in Madrona, as of the 2020 Census. Only one block in Madrona was at least 40% black as of 2020, and many blocks west of 34th Avenue have become less than 10% black. Black residents made up 9.6% of Madrona's overall neighborhood population in 2020.

That's all for now, but I'll end with a full list of figures and maps in the book. It's an absolute gold mine!
A list of the first 27 figures in the book. Topics include cholera, zoonotic diseases, global calorie and protein intake, cancer, and tuberculosis. A list of the final three figures in the book: (28) Deaths from all causes in Britain, 1954-1958; (29) The temperature-humidity limits of human comfort in Hong Kong, presented above; and (30) Mental illness in England and Wales.

A description of the US leading the way in milk pasteurization, presented without comment.
Snippet from page 54: "The United States led the way in demanding the strictest control of milk and insisted on pasteurisation. For long it was a special pride of a dairy or dairy farm to market TT milk (Tuberculin tested) and a higher price was charged."

Now, some snippets showing how much things have changed... the author predicts that "we ourselves are living in the very midst of a campaign for the complete eradication" of malaria, while polio is described as globally endemic.
Snippet from the book: "The story of the unravelling of the riddle of malaria is one of the great romances of science, and we ourselves are living in the very midst of the campaign for complete eradication of the disease." Malaria remains one of the top infectious disease killers of children under 5 worldwide. Snippet from a discussion of polio: "A map showing known distribution of polio is in fact a map of the world distribution of population."

A table of leading causes of death across the United States in 1949 and 1960. Note the three-quarters reduction in TB deaths over one decade!
Table of leading causes of death across the United States in 1949 and 1960. Deaths from infectious diseases, including TB, syphilis, typhoid, diptheria, whooping cough, and polio all drop precipitously from 1949 to 1960. Strokes, nephritis (kidney inflammation), and prostate cancer are all listed as "deaths of old age".

These complicated figures accompany a chapter on heat strain, where the author correctly predicts that air conditioning will change the possibilities for human settlement over the coming century:
This "climagram" figure shows estimated physical strain for moderate activity, shown via sloping lines that range from 10% to 90%, under different temperature and humidity conditions. Example ranges are shown for six different cities and times of day. Figure showing human "comfort zones" based on temperature and humidity during the summer and winter months in Hong Kong. The author points out that climate-controlled indoor spaces will allow people in a wider range of geographies to live comfortably throughout the year.

Another interesting parallel with today: estimating the spatial distribution of cancer across Britain is still the canonical case study used to demonstrate disease mapping techniques.

Compare the map below to this chapter from @paulamoraga.bsky.social's book: www.paulamoraga.com/book-geospat...
Distribution of stomach cancer among British men, 1954-1958.
