Fertility, birth, reproduction: Connecting formal demographic frameworks The conventional framework of fertility research conceptualizes childbirth from the mother’s perspective. From her perspective, birth is an uncertain and potentially recurring event. In contrast, t...

✍️ Just out: Annette Baudisch & I delve into the formal demography of fertility, birth, & reproduction timing. 👶 We use methods from mortality research to summarize when in the parental life course children are born. 📆 1/n

Let's be clear: no one should be taking medical advice from the man who told Americans to inject bleach.

To moms worried about the Tylenol they took while pregnant: you deserve better than being RFK Jr's scapegoat.

And to the autism community: you are loved exactly as you are.

Pretty clear illustration of "you may as well stand up for what you believe in, they're coming for you anyway."

Does anyone want to be formal demography reading buddies? I have a bunch of areas I’m trying to read up on and I feel like I’d get it faster if I had someone to explain results to and ask questions of.

A blog from me on why social science infrastructures matter. I talk about the value of social science data collections & data services (especially @ukdsimpact.bsky.social), current opportunities and challenges (including AI, the growth of TREs & training), & what we're doing about them at ESRC.

Recalling that COVID still ranks in the top 10 causes of death in the US since 2023, while it ranked third in 2021-2022! So it had not only an important impact during the height of the pandemic, but it also remained a leading cause of death overall thereafter.

How many people died of COVID? We likely undercounted, not overcounted COVID deaths

Persistent minimizing of the COVID death toll hits me especially hard in the #demography feels. To be clear:

➡️ Over one million Americans died of COVID-19.

➡️ Official COVID deaths were likely undercounted, not overcounted.

Graphic describing some of the key features of the study: 30,000 babies will take part, it is the first new UK-wide birth cohort study in 25 years, babies will be age 9-11 months at the first survey, and 3-4 years at the second survey.

Graphic showing sample sizes in the four UK countries: 16,300 babies in England, 5,000 babies in Scotland, 4,500 babies in Wales, and 4,200 babies in Northern Ireland.

Graphic describing some of the elements of the study. This includes boosts for ethnic minority and low income families, interviews with fathers as well as mothers, consent to linkage to administrative data.

We're excited to announce CLS will lead the first new nationally representative UK-wide birth cohort study in 25 years. Generation New Era will follow the lives of more than 30,000 babies born in 2026, during their early years, and potentially beyond. Read more: bit.ly/4gfttBP

EBV induces CNS homing of B cells attracting inflammatory T cells - Nature Epstein–Barr virus infection generates a neuroinvasive B cell subset, which recruits activated T cells to the central nervous system, promoting multiple sclerosis.

Before COVID we didn’t even know a virus causes multiple sclerosis. They just figured out how it does it.
