The 2025 American Community Survey should have come out today. But it has been delayed because of unusual political encroachment at Census. ACS drives business and policy decisions, especially in local communities, and is the primary input to Census’s immigration estimates.

Abstract
This paper examines the relationship between union membership and deaths of despair. Using state-level variation in the timing of the adoption of right-to-work laws as a natural experiment, I show that right-to-work laws are associated with a decline in union membership and an increase in deaths of despair. Two-way fixed-effects (TWFE) difference-in-differences (DiD) estimates suggest that the adoption of a right-to-work law is associated with a 2.6 percentage point reduction in union membership and an increase in deaths of despair mortality of 13 additional persons per 100,000, implying there are approximately 7.5 additional deaths of despair for every 1,000 workers who lose union membership. An analysis of mechanisms suggests the increase in mortality is largely driven by increased opioid usage and a concomitant increase in overdose deaths. I support the TWFE results with estimates from two alternative estimators robust to concerns about treatment effect heterogeneity and variation in treatment timing. Estimates from the Callaway and Sant’Anna (2021) estimator and the Borusyak et al. (2024) estimator support the TWFE findings: right-to-work laws reduce union membership and increase deaths of despair.

So-called right-to-work (RTW) laws undermine workers’ ability to form unions. Unionization rates are clearly lower in RTW states—and since unions raise wages, that suppression lowers pay. The latest from @elisegould.bsky.social and Emma Cohn examines the economic impact of RTW 👇 1/7 #econsky

The latest administrative data show the BLS payroll survey got 2025 job growth right, but this appears to have escaped the dude running the Department of Labor, who still points to revisions as evidence the agency can't be trusted. Maybe the credibility problem isn't the agency's?
What to watch: Sonderling acknowledged that BLS faces a credibility problem.

"A lot of people don't trust BLS anymore," he said, pointing to a large downward revision released after the 2024 election that showed Biden-era job growth was weaker than initially reported.
The revision "really hurt the credibility" of the agency, he said.
"I've made a commitment to reform that and be much more transparent on how some of these revisions and job data are done," Sonderling said.
The other side: Trump raised a different set of concerns about BLS credibility when he fired commissioner Erika McEntarfer last summer, accusing her without evidence of rigging the data.

The firing prompted economists across the political spectrum to warn that political interference could undermine confidence in BLS data.
