This is my favorite plot from this post, showing life expectancy at three spatial scales:
- Countries of the world (range: 51 to 85 yrs)
- Counties of the US (66 to 90 yrs)
- Census tracts in King County, WA (71 to 87 yrs)
At each scale, averages hide dramatic spatial heterogeneity in health

- Census tracts in King County, WA (71 to 87 yrs)

Mayor Katie Wilson! She kicked off her term with an impressive display of stamina—I was near the back of a looong reception line.

In my testimony, I argued that the City of Burien's camping ban was spatially illegible: the prohibition zone was defined in a complicated way that invited mistakes from city mapmakers and the general public.

In my defense, the WA Bikes board is appointed by, and entirely composed of, the Cascade board. I think it's reasonable to ask Cascade board candidates about their positions on WA Bikes issues!

When @cascade.org announced its board elections, I followed up to ask if the candidates had public stances on this year's WA Bikes endorsements.
Unfortunately I didn't hear back until today (voting closed yesterday), but I'm sharing the response for anyone interested in how these endorsements work.

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

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.

New from ProPublica: Black and Hispanic students made up just 11.7% of the student population in Seattle's private schools, compared to 28.8% of students in Seattle Public Schools.

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
