Thank you to everyone who joined us for our webinar, The Day Federal Data Went Dark: A Year of Monitoring and Action. We are grateful to be in a community with so many amazing organizations.

You can watch the recording to learn about more than a dozen efforts to monitor and safeguard federal data.
The Day Federal Data Went Dark: A Year of Monitoring and Action
January 31, 2025, is infamous as the day thousands of federal datasets and webpages went dark. While many of these resources have since been restored–often after being scrubbed of references to gender, DEI, and climate–they continue to face significant risks. In the webinar, we mark the one-year anniversary of this takedown to discuss the current state of federal data and recognize the immense amount of work that has been done to defend these public resources. Leaders from the data community will share insights on monitoring tools they have developed and the actions being taken to safeguard essential federal data. This webinar is cohosted by dataindex.us and the Association of Public Data Users. 0:00 Introduction 2:53 EssentialData.US x Federation of American Scientists 6:51 American Statistical Association 10:31 CDC Data Project 14:17 Friends of BLS 17:50 Public Environmental Data Partners 21:24 The Leadership Conference Education Fund 26:26 Movement Advancement Project 30:37 Population Association of America 35:05 Democracy 2025 40:42 Data Rescue Project 44:16 Population Reference Bureau 47:14 Association of Public Data Users 50:10 dataindex.us 55:19 Conclusion

How many STEM Ph.D.s were lost from the U.S. federal government last year?

My colleagues @mghersher.bsky.social and @policyhound.bsky.social dug into a recent data release to find the answer. A @science.org exclusive.

Paid family leave improves the health of US families. Read our new research brief on #PaidLeave: hsph.harvard.edu/wp-content/u...

The US remains one of only six countries in the world without national PFL - we can do better. @paidleaveforall.bsky.social

Some important points from new study: if you describe specific safety net programs (eg SNAP, unemployment insurance) instead of generic "welfare programs," people are more likely to tolerate slightly higher fraud to ensure access. There is always this trade-off; framing matters. @donmoyn.bsky.social
People are willing to accept a fraud access tradeoff. More specifically, the accepted allowing about 1 case of fraud to ensure access for 5 eligible claimants. For every ineligible person who might wrongly receive benefits, Americans are willing to ensure five eligible people get help.

@christinajcross.bsky.social's fabulous book painstakingly details how family structure is - and isn't - related to children's academic achievements, including insights into why pushing marriage won't alleviate race and ethnic differences in achievement.

What happens to self-reported race/ethnicity when you change the way you ask it?

There is some discordance.

And it is consequential for estimating quantities of interest, like disease risks by population group.

Thanks to @sabrinamalhi.bsky.social @washingtonpost.com for covering this study, including the fact that recent cuts in spending for youth #mentalhealth are likely going to prevent us from addressing the long-term consequences of school closures: www.washingtonpost.com/health/2025/...
Going back to school during the pandemic linked to improved child mental health
A new study finds that school reopenings during the pandemic were associated with declines in diagnoses of anxiety, depression and other mental health conditions in children.

Youth Mental Health Improved When Schools Reopened, Study Finds
www.nytimes.com

We used quasi-experimental diff-in-diff analysis & commercial claims data on 180,000 kids. Of course, usual limitations apply in terms of possible time-varying confounding, like other COVID policies. Also, healthcare *utilization* does not necessarily = health. journals.lww.com/epidem/abstr... 5/5
journals.lww.com

Our study findings resonate with another recent study @stanfordeducation.bsky.social finding that kids' test scores dropped during the pandemic, especially math scores for girls. Gendered patterns in social interactions may help explain this. apnews.com/article/math... 4/
The gender gap in math widened in the pandemic. Schools are trying to make up lost ground
Efforts to close the gender gap in STEM education are gaining momentum after setbacks during the COVID-19 pandemic.

Does this mean schools shouldn't have closed during pandemic? No, #publichealth folks were making decisions based on available evidence under uncertainty. It does mean policymakers should balance physical well-being (infections) & mental well-being in the future. journals.lww.com/epidem/abstr... 3/
