1924 Minneapolis density zones as an instrumental variable for rapid response networks

I haven't seen any changes to zoning because of this 😉

Less of a problem for e.g studies of birth to age 30, for which we have more studies in more places across more birth cohorts

Evan Roberts @evanrobertsnz.bsky.social · 6h

Neologism is good! Indeed, there is a challenge in life course studies that the subject is young enough that we don't have a lot of cohorts that have been studied cradle to grave, and so we don't know how well studies generalize across time and context.

Unfortunately studying old people means waiting a long time. Significant cognitive decline on a population scale is not super evident until people's 70s, so Great Depression & just post-WWII cohorts are first ones we can really study this in at scale.

Good reminder that a word I use several times a week in a professional context is indeed specialist jargon 😀

Bad news for all those suckers out there who chose to have siblings! You're making each other's cognitive decline go faster in later life.
www.demographic-research.org/articles/vol...

Background: Siblings are the most common household companions in childhood, yet demographers know little about how sibship configurations reverberate across the life course to shape population‐level cognitive health at older ages.

Objective: The author assesses whether coresiding siblings in childhood are linked to late-life cognitive trajectories and asks how associations differ by sibship size, age spacing, and sex composition.

Methods: This study uses 12 biennial waves of the Health and Retirement Study (1998–2020; 42,530 person-wave observations) linked to respondents’ records in the 1940 full-count US census (N = 6,187). The author estimates late-life cognitive decline trajectories by childhood coresiding sibship structure, adjusting for childhood socioeconomic, demographic, geographic, and household attributes alongside time-varying adulthood health covariates.

Results: Compared with only children, individuals who coreside with more than one sibling experience faster annual declines in cognition, net of covariates. Decline steepens monotonically with each additional sibling and is faster when at least one sibling is closely spaced. Men raised with only brothers display the lowest baseline scores, whereas women, especially those with brothers, show the most rapid deterioration. Findings are robust to birth order controls and alternative model specifications.

Conclusions: Resource dilution in large or closely spaced sibships erodes cognitive reserve over the life course, consistent with gendered sibling caregiving norms that magnify women’s later life risks.

Contribution: By merging historical census data with longitudinal survey data, this study provides evidence that childhood sibship structures have enduring, gender-contingent associations with cognitive aging, highlighting siblings as an overlooked demographic determinant of population health.

Research ethics ? (please send resources!): I'm writing about publicly available court cases from 1970s describing gender-based violence (SA, DV). Victims' names are listed. Citations for the cases is "In Re [victim name]..." Ok to name victims in text? Feels violating, but maybe I'm overthinking.

Book is about veteran suicide, but I’ve also read lots of obituaries of death by other causes where (from death certificates) I know the cause.

Evan Roberts @evanrobertsnz.bsky.social · 21h

i also have this question in my head. from my book research I can say 1) this phrase is old and international, and 2) illness is sometimes true, sometimes euphemistic for suicide

If China takes over Canada, and Minnesota becomes South Manitoba in the War of Stupid Secession, then by the transitive principle NZ dairy products will be available duty free in Minnesota, and I won’t have to eat this inferior midwestern grain fed stuff.

Evan Roberts @evanrobertsnz.bsky.social · 22h

Most people are focused on the out of touch hilarity of “Canada will eliminate the Stanley Cup”, but a close second is any notion that the US is committed to free trade in dairy products.

Minnesota, where the same place can look very different in different seasons [as opposed to my hometown where you can look at a photo and not know what time of year it was]

Is this the same place?

#InfillFriday These two 3 story duplexes going up in Minneapolis are mildly interesting. Front duplex is popping up one story on a 1900 house. Back lot building is new. On a 10k lot this is pretty modest density. Note they're under mature tree line

Since we're crayoning:
Here's a challenge.
Pick a metro area.
You can build 10 miles subway, 20 miles elevated rail, or 40 miles at grade (street, freeway, rail ROW) rail (or any suitably weighted combination.)
Where do you put it for max ridership?
How do you adjust the bus network to work with it?

Being unfair to the 95 final. Outcome was horrible for NZ, but it was a gripping game, and seeing Mandela be part of the South African celebrations was probably good for SA and the world.

Yeah. Saved feels different from Slow Train Coming and Shot of Love. Never have quite grasped the trajectory across those three albums.

Have you thought about it from the cats perspective though? 🐈‍⬛

If I recorded my foam rolling time it would often be "With Pet" because she's fascinated when humans get down to her level and do weird cat- like stretches.
