Friday was my last day at WIRED. Today I started a new job at Bloomberg on a dream desk with @suryamattu.com and @jeffykao.bsky.social.

Got a tip? A dataset? Something we should look at? Find me on Signal at dmehro.89

In no particular order, here’s some stuff I’d like to continue to dig in to:

Good "missing data" story
crampell.bsky.social
When Trump encounters a demographic he doesn’t care for, he “disappears” them–in many cases, the very record of their existence.
Meet America’s new “missing persons," and the govt campaign to delete statistical evidence of anyone who doesn't fit Trump’s idea of our new golden age.

Opinion | Here are the people Trump doesn’t want to exist
Women, people of color and those in the LGBTQ+ community are main targets.

NEW: The US government has collected DNA samples from 133,000+ migrant children and teenagers and uploaded them into CODIS, a national criminal database originally built for convicted sex offenders and violent criminals, according to documents reviewed by WIRED.
The US Is Storing Migrant Children’s DNA in a Criminal Database
Customs and Border Protection has swabbed the DNA of migrant children as young as 4, whose genetic data is uploaded to an FBI-run database that can track them if they commit crimes in the future.

I see your point! I was just using the domain term to contrast from arrests at or along the Southern border. But yeah the North, (also Midwest) and elsewhere in the country, too. Thanks for tuning it!

Sounds like a cool project! Thanks for reading

Thank you for reading, I'll share that feedback with the team!

This is a great story, the kind of great story you can do through using the data released by The Deportation Data Project: deportationdata.org

Every data reporter covering immigration should get familiar with the data here
leonyin.org
100%, such a rich dataset. Thanks for sharing Will!
leonyin.org
Our analysis uses records from the Data Deportation Project. They FOIA'd ICE for arrest and detention records of over 3.5 immigrants spanning Obama's second term to the first four weeks of Trump's second term. This data is available for anyone to use:

This trend is partially due to historic lows in border arrests (freeing up space in the largest ICE facilities), and an increase in interior arrests. However, interior arrests aren't at a historic high, and the NE's largest detention center in had over 400 beds open. bloom.bg/43am95w
leonyin.org
When immigrants are transferred across state lines they often need to get new legal counsel. ICE detention facilities in the South and SW are remote, with immigration lawyers few and far between. The avg distance to the closest immigration lawyer in Louisiana is over 100 miles.

leonyin.org
In prior years few immigrants detained by ICE in the Northeast were sent to the South & SW. Virtually nobody sent to New Mexico, and less than 1% of ppl sent to Texas or Arizona. In Trump's first month, 12% of ppl detained in the NE were sent to Texas, 4% to NM and 3% to AZ.

The Rising Cost of ICE Flying Immigrants to Far-Flung Detention Centers
The increase in long-distance transfers makes it harder to fight deportation and boosts taxpayer expense.
bloom.bg
leonyin.org
Getting transferred to the South and SW reduce detained immigrants' chances at staying in the country. 70% of people detained in Louisiana and New Mexico end up deported, which is double that of the Northeast and the Nat'l Avg, which is about 50%.

After a big story we (reporters) go back to zero. It's a lifeless and cold wasteland. Sometimes we shine a light down a new rabbit hole and see new potential to start digging again.

come on down and say what up! (if you're going NICAR)

Thanks! The impact is a result from our super team, especially @natalielung.com for her continued reporting on the topic!
