Tucson's Migra Map: How a PhD Student and a Spreadsheet Are Charting ICE Activity in Arizona

If you want a snapshot of how immigration enforcement is reshaping daily life in the American Southwest, skip the cable news shouting and look at a map. Specifically, look at the Tucson Migra Map, a community-built tracker stitched together by volunteers, geography nerds, and a stubborn belief that public information should actually be, well, public.

What the Map Actually Does

The Tucson Migra Map, hosted at tucsonmigramap.com, plots verified accounts of immigration enforcement activity across Tucson and the surrounding area. It was built by Dugan Meyer, a PhD geography student at the University of Arizona who volunteers with Tucson Rapid Response. The data has been collected in spreadsheets since January 2025, then filtered, vetted, and pinned to a map only after the fact.

That last bit is the crucial difference. Other trackers, such as the now-defunct People over Papers (which Padlet pulled offline citing content policy violations) and the much-discussed ICEBlock app, leaned towards real-time alerts. The Migra Map deliberately does not. Meyer argues the post-incident approach is closer to a FOIA-style public record than a panic button, and that publishing verified, after-the-fact information is squarely protected by the First Amendment.

The Numbers Behind the Pins

As of late April 2026, the team had reviewed roughly 562 reported incidents and judged about 300 of them solid enough to include on the map. That filtering matters. A tracker that publishes every rumour quickly becomes useless, or worse, dangerous. One that publishes nothing is just a blog. The Migra Map is trying to live in the awkward middle.

The wider context is what makes the project feel urgent. Arizona-wide ICE arrests more than tripled in fiscal year 2025, climbing from under 200 in late 2024 to more than 800 by June 2025, according to FOIA records analysed by the Deportation Data Project and reported by AZ Mirror. That is a state-level figure rather than a Tucson-only one, but it gives you the shape of the surge driving demand for tools like this in the first place.

Why a Map, and Why Now

Mass deportation has been a cornerstone of President Donald Trump's second-term agenda, and Arizona, with its long border and busy enforcement corridors, has been one of the loudest test cases. Local mutual aid groups, including La Bodega, founded by activist Lucia Vindiola, have stepped in where federal transparency has not. The El Super grocery store on Tucson's south side has reportedly seen a particularly high concentration of enforcement activity, the kind of granular detail that only emerges when residents pool their observations.

For UK readers wondering why this should land on your radar, think of it as a case study in civic mapping under pressure. The same questions, what counts as a verified incident, who gets to publish it, and where the line sits between transparency and tipping off targets, are showing up in debates over Home Office enforcement, asylum hotel protests, and police data here too.

The Taco Giro Raid

One incident has come to symbolise the tension around all of this. On 5 December 2025, federal agents executed 16 warrants across Southern Arizona as part of a multi-year investigation into alleged immigration and tax crimes linked to the Taco Giro restaurant chain. Forty-six people were arrested.

Among those caught up in the chaos was Democratic Representative Adelita Grijalva, who said she was pepper sprayed by federal agents during the raid. Tucson Mayor Regina Romero and reporting from AZ Luminaria backed her account. The Department of Homeland Security pushed back, with spokesperson Tricia McLaughlin telling Fox News that Grijalva was simply standing near someone else who was sprayed for allegedly obstructing officers. The two versions cannot both be entirely right, and the dispute itself is part of why locals say they want a map: when even a sitting member of Congress and a federal agency cannot agree on what happened, ordinary residents have little hope of getting a straight answer about a raid at their corner shop.

What Makes This Tracker Different

Plenty of activist tech projects fall into one of two traps. They either move so fast they amplify rumours, or they move so slowly they become irrelevant. The Migra Map's choice to publish only verified, post-incident reports is genuinely interesting because it is a deliberate trade-off, not an oversight.

You lose the ability to warn someone in real time that agents are at the petrol station up the road. You gain credibility, a defensible legal position, and a dataset that researchers, journalists, and policymakers might actually trust. Given that ICEBlock has reportedly faced pressure to come offline (a claim that floats around news coverage but which we could not independently verify in current reporting) and People over Papers has already been shut down by its host, the slower approach also has the advantage of being harder to kill.

The Civil Liberties Question

Inevitably, projects like this provoke a debate about whether they help communities or hinder enforcement. Meyer's framing, that the map is essentially a citizen-run public record, is a clever bit of legal positioning. It nudges the project towards the same protected territory occupied by court reporters, FOIA-driven databases, and watchdog journalism.

Whether courts ultimately agree is another matter. The First Amendment shields a lot, but the political appetite to chase down enforcement-tracking tools is not exactly subtle right now. Expect the legal questions to get more, not less, interesting in 2026.

The Verdict from Across the Pond

You do not have to take a side on US immigration policy to find the Tucson Migra Map worth watching. It is a small, specific, low-budget piece of civic infrastructure that is asking a big question: when official data is patchy, contested, or simply absent, who gets to fill the gap, and on what terms?

If it works, expect copycats. If it gets shut down, expect a fight. Either outcome will tell us something useful about the state of digital civil liberties in 2026.
