Department of Homeland Security
GovernmentThe Department of Homeland Security collects and publishes operational data across its multiple agencies and missions, including U.S. Customs and Border Protection, Immigration and Customs Enforcement, the Transportation Security Administration, and the Federal Emergency Management Agency. Their datasets cover border crossing volumes, apprehensions and enforcement actions, security incident reports, disaster declarations, and infrastructure vulnerability assessments. DHS data is often used by policymakers, researchers, and journalists to track immigration enforcement trends, border security measures, and emergency management activities.
Pinned datasets
DHS Yearbook - Lawful Permanent Residents by Country
How many people got green cards last year, and where were they from? This data answers that question for every country in the world, going back a decade. You can see which countries send the most immigrants to the US, how those patterns have shifted over time, and compare regions. It's the official count from Homeland Security, published every year.
DHS Yearbook - Naturalizations by Country
Not all immigrants become citizens, and this data shows who did. For each year from 2014 to 2023, you can see how many people from each country took the final step to become US citizens. Some countries send far more naturalizations than others. Mexico, China, India, and the Philippines have historically led, but the numbers shift year to year. If you're curious whether naturalization rates are going up or down, or which countries have citizens most likely to become American, this is where to start.
DHS Immigration Enforcement Monthly Tables
Immigration enforcement actions reported each month by DHS, broken down by what happened to people: removals (forced returns), voluntary departures, administrative returns, and expulsions under Title 42. You can see month-by-month trends in how many people were deported, chose to leave, or were expelled, going back to 2014. Useful for tracking enforcement activity changes, comparing months and years, or analyzing the effect of policy shifts.
DHS Fentanyl Disruption Seizures
In FY2023, DHS agents seized over 20,000 pounds of fentanyl across the country and arrested people running pill press operations. This data shows how much fentanyl they grabbed each month, which regions are hotspots for seizures, how many pill presses they shut down, and how much cash they confiscated. It's a month-by-month breakdown of a specific federal enforcement effort, so you can see if seizures are going up or down and which parts of the country are dealing with the heaviest trafficking.
