The State of the American Housing Market has been updated with May data!

Inventory rose 31.5% compared to last May. Notably, this is the first month since December 2019 where the number of active listings surpassed 1 million. The median list price remained steady from a year ago at $440,000.

Good idea. Even in this environment it was shortsighted of ABC to completely shutter 538. www.semafor.com/article/05/1...

Polls conducted after Trump's new tariffs are just brutal for him:

- Net approval rating hits a new low of -4
- Disapproval over 50% for the first time in his second term
- Econ approval at -15
- Tariffs underwater by 30

Will be updating this post with more: www.gelliottmorris.com/p/trump-appr...
Live updates: Trump's approval hits new low after "Liberation Day" tariffs
His average economic approval also hits a new low (-13), and his tariffs are underwater by 30 points

Several big 538 projects have made on the long-list for the 2024 Information is Beautiful awards. A big honor for a small group of journalists. Congrats to the team ❤️ www.informationisbeautifulawards.com/showcase?act...

ABC News has now fully taken down the old 538 website, including all interactive projects since 2014. Aside from erasing history this prevents access to publicly released data, including raw polls, averages, model estimates & story dta. Totally unacceptable for a company (allegedly) doing journalism

Along with the rest of the staff, I was laid off from 538 today. I am incredibly proud of the work we did there and honored to have learned so much from such talented journalists.

As reported, the entire staff of 538 was laid off this morning. This is a severe blow to political data journalism, and I feel for my colleagues. Readers note: As we were instructed not to publish any new content, all planned updates to polls data and averages are canceled indefinitely. Huge loss :(

It's true. ABC News shuttered 538, and I was laid off today. It was an honor to work with a talented, smart and most importantly, kind, group of journalists; and to build off the groundbreaking work of the those who came before me.

Incredibly sad to report that ABC News is indeed eliminating 538.

I count myself incredibly lucky to have worked with such incredibly smart, kind people for 7 years. Thank you all for coming along for the ride.

Trump could have the most failed Cabinet nominations to start a presidency. abcnews.go.com/538/trumps-c...

The record is 3, and Gaetz was the earliest Cabinet withdrawal in modern history.

The @washingtonpost.com, @lhreports.bsky.social and @eluniversalmx.bsky.social collected death records from every Texas county and Mexican state bordering the Rio Grande to examine the effects of tougher enforcement, and whether it has increased drownings:
