I mean, why would we need official statistics when a DoorDasher can bring it, lukewarm and possibly missing an item, to our door (and sometimes to our neighbor's door, but who's counting)?

And @karenguzzo.bsky.social doing an incredible job of explaining the difference between period and cohort fertility (without saying either of those terms, because this is largely a policy audience) and the implications.
Audience is paying very close attention.

It's a downer of a shutdown day, but on the bright side, I get to see colleagues W Schwarm, @karenguzzo.bsky.social, E Zheng, and K Kane talk about population trends at the annual @scagnews.bsky.social Demographic Workshop.

Can anyone explain to me why telework rates in 2024-25 are higher than in 2022-23 (according to CPS)?
Is it real? (It certainly debunks the RTO narrative.)
Is it a methodological shift?
Is it labor market shift? (I don't see anything obv in industry or occupation mix but maybe I missed something?)

The "last updated" date on this National Survey of Children's Health page is a lie.
I have a copy of the data and codebook from Oct 2024.
The materials there today are missing at least one key measure: whether or not the child faced discrimination for their sexual orientation or gender identity.
