The Uncontrolled Policy Experiment on Trans Youth

“The US is conducting a large-scale, uncontrolled policy experiment on trans youth. At the same time, federal actions are dismantling the systems needed to measure the consequences.”

PSC Coffee Chats are Tuesdays at 10. Winter 2026: Feb. 17, Mar. 17 (Pi/e Day), and Apr. 21 at ISR Thompson 2116

Today! Join us for PSC's coffee chat monthly Tuesdays at 10 for baked goods and brief interviews. Our research administrator Sabrina Garber is today's guest. All are welcome!

❤️ It’s up there with the best kinds of love. #DemographerLove

Check it out @asanews.bsky.social #ASA2026 attendees!

At our recent @um-psc.bsky.social coffee chat, Ana Reynoso named PSID, alongside Scandinavian registry data, as her favorite data source. Follow @umpsid.bsky.social and use this rich, longitudinal data on income dynamics to improve lives. #LoveData26 Video: @abbymehraban.bsky.social

Three-column infographic comparing Business owners, Formal self-employed, and Informal self-employed, each with an icon at the top (buildings, briefcase, and a bicycle courier) and a list of outcomes; Business owners column lists Higher earnings, More stable, Best health, and Highest life satisfaction with corresponding icons, Formal self-employed lists Moderate earnings, Some stability, Better health, and Higher life satisfaction, and Informal self-employed lists Lower earnings, Less stable, Poorer health, and Lower life satisfaction; footer text reads Based on PSID data from 2003 to 2019.

Not all self-employment offers the same security.

New U-M research using PSID data on about 10,000 U.S. families finds informal gig and odd-job work is tied to lower earnings, poorer health, and more instability. ISR researcher Joelle Abramowitz explains why these distinctions matter.

Graphic on a dark blue background with the ISR logo at top left, a yellow silhouette map of Denmark on the left with a dark blue silhouette of an adult lifting a child, and large yellow text on the right that reads Denmark policies offset about 80% of the motherhood earnings penalty with the 80% circled in red; along the bottom are three labeled icons reading Child Allowances (stacked coins with a person symbol), Paid Leave (calendar with a check mark), and Subsidized Child Care (house with a baby stroller).

Denmark shows how policy can reduce the motherhood earnings penalty.

ISR researcher @sashakillewald.bsky.social finds paid leave, child allowances, and subsidized child care offset about 80% of mothers’ earnings losses.

Denmark’s generous child care and parental leave policies erase 80% of the ‘motherhood penalty’ for working moms Two researchers found that Danish government benefits do not fully offset moms’ lost earnings. But they do help offset lost income for working women with kids.

ICYMI: our own Stone Center Director @sashakillewald.bsky.social explores the costly ‘motherhood penalty’ and how one country is erasing it. Learn more in her article from the@us.theconversation.com:
