LGBTQ+ adults in the US have distinct partnership and living arrangements often missed in surveys: less often married, more likely to cohabit or have non-coresidential partners, and more likely to live alone, with roommates, or in smaller households.

Figure 1 showing adjusted predicted probabilities of student’s expectations–enrolment by migrant background.

Academic expectations don’t always become reality. @etrappolini.bsky.social, Di Patrizio & Giudici show that migrant-origin students — especially later arrivals — are less likely to enrol in university than Italian peers with similar expectations.

A figure showing diagrams about the probability of the number of kin for cousins and sisters at 20 years and 50 years of age. Cousins (age 20) mean=0.8, sd=0.92, skew=1.19; Cousins (age 50) mean=0.77, sd=0.9, skew=1.21; Sisters (age 20) mean=0.88, sd=1.01, skew=1.24; Sisters (age 50) mean=0.84, sd=0.98, skew=1.26

“How many sisters or cousins will you have? We've developed the first method to calculate the probability distribution of kin numbers across your lifetime – not just averages, but actual chances of having 0, 1, 2+ relatives at each age.”

Figure showing predicted cognitive functioning trajectory with years since baseline by sibship size, Health and Retirement Study, 1998–2020, linked to the 1940 census (N = 42,530 person-wave observations)

Using HRS data linked to the 1940 Census, @yiangli.bsky.social shows that individuals with more childhood co-residing siblings are linked to steeper late-life cognitive decline, and women raised with brothers show the fastest deterioration.

Who else is in the room matters. Third-party presence during interviews strongly influences infertility reporting and partner agreement about their ability to have a child.

We are inviting you to submit contributions to a Special Collection on the Socioeconomic Inequalities in Mortality in the Long-Run, organized by K. Thompson, T. Riswick & S. Clouston. Submissions to this collection are possible from January 28, 2026 until June 28, 2026. (1/2)

Loneliness has a demographic footprint. The new essay from @hpa_passarelli outlines how relational disconnection interacts with mortality, fertility, and migration – and why it matters for understanding population change. #Demography #Loneliness

Thanks @jomuzhi.bsky.social for so gracefully pointing out my mistake - and causing me to panic and make it even worse. 😉

Oh, we really messed up now! Didn't mean to delete the post about today's publication and the apology for the wrong graphic!! But third time's the charm - maybe will get it right this time. Stay glued to your screens to witness success (or failure) in real time!

Is Korea’s marriage decline real – or just delayed?
A new study uses tempo-adjusted indicators to unpack 30 years of change – postponement, structural shifts, and pandemic effects.

Diagram of the mean age difference in Ghana and in Kenya for the survey period 1990 to 2024

In Ghana and Kenya large spouse age gaps (ten years and above) are falling. The decline in Ghana is driven by more educated men; in Kenya there is a shift in partner selection. Smaller gaps, more equity. #GenderEquity #Agegap @demographyvienna.bsky.social

Using unique couple-level data, we identified six life-course couple migration patterns in China. We found that wives who reunited with their migrant husbands have fewer depressive symptoms in later life than left-behind wives.

Using UKHLS data, @claudiabrunori.bsky.social shows that transnational separation is widespread among childhood immigrants, underscoring the need for targeted survey questions and more research of its consequences.

A global study of 913k Zoe users shows lesbian (48%) and bisexual (40%) identities dominate worldwide, while younger generations show rising diversity, with 6.6% pansexual, 3.4% queer, and 0.7% asexual. Sexuality is evolving globally.

Unrealized fertility—having fewer children than desired—is common across the globe yet has been under-studied. A new paper in Demographic Research reviews what’s known and argues for a more coherent approach to its study across contexts.

Wars that leave families some agency can transform parenting: fewer children, better care, improved survival. Conflict isn’t always only destruction. @hcebolla.bsky.social @cchscsic.bsky.social @csic.es

How do grades differ for children in stepfamilies formed through cohabitation compared to remarriage? This study fills a research gap by highlighting the educational disparities between children in cohabiting and remarried stepfamilies.
