Pronatalist policies are rising as birth rates fall. In The Lancet, LCDS researcher @sanderwagner.bsky.social says support should focus on autonomy, fertility care, childcare and parental leave — not pressure. Read: www.thelancet.com/journals/lan...

Concerns over reproductive rights as pronatalism increases

“It is time to reflect on whether or not to have a child.” That will be the opening line of a government letter being sent to 29-year-olds in France in June, 2026. Aiming to address infertility, the l...

Now, that is a super cool way of applying Caswell's formal demography of kinship framework ! #Demography #Kinship

What can demography teach us about the "gay cousin at Thanksgiving" meme? A lot! If you were born in the 80s, 90s, or 00s, you could have one queer cousin, on average*. Younger cohorts have fewer cousins overall, but still have a strong share who are queer. * for an American woman in 2023.

Day 2 of kinship workshop, we moved into richer terrain with two-sex, time-varying models and spent time unpacking a powerful idea : kin loss and bereavement One striking insight: in India, an individual aged 100 in 2020 would have experienced the loss of nearly 45 kin over their lifetime!

Over a dozen ways to decompose life expectancy, all in one (we hope) friendly interface. Please have a look at the LEdecomp R package cran.r-project.org/web/packages... See the function LEdecomp() for access to all of them. If we left something out, please shout! #rstats #demography #mortality

What is the most profitable industry in the world, this side of the law? Not oil, not IT, not pharma. It's *scientific publishing*. We call this the Drain of Scientific Publishing. Paper: arxiv.org/abs/2511.04820 Background: doi.org/10.1162/qss_... Thread @markhanson.fediscience.org.ap.brid.gy 👇

We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing: a 🧵 1/n Drain: arxiv.org/abs/2511.04820 Strain: direct.mit.edu/qss/article/... Oligopoly: direct.mit.edu/qss/article/...

A table showing profit margins of major publishers. A snippet of text related to this table is below. 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A). Their profit margins have always been over 30% in the last five years, and for the largest publisher (Elsevier) always over 37%. Against many comparators, across many sectors, scientific publishing is one of the most consistently profitable industries (Table S1). These financial arrangements make a substantial difference to science budgets. In 2024, 46% of Elsevier revenues and 53% of Taylor & Francis revenues were generated in North America, meaning that North American researchers were charged over US$2.27 billion by just two for-profit publishers. The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year.
