In this blog post, I use #RStats to explore publicly available ICE arrest data. #Dataviz shows recent trend where ICE are primarily targeting/locating people without criminal records in communities.

Code along and take a look for yourself: jef.works/blog/2025/09... #CodeTutorial

People are being arrested by ICE. What countries are they from?

I analyze public data from deportationdata.org/data/ice.html to find increased arrests for immigrants from many countries #FirstTheyCame

Code so you can reproduce these trends for yourself: gist.github.com/JEFworks/1f0...

I visualize trends in #ICE #immigration arrests and encounters over time and across select US cities using public data from deportationdata.org/data/ice.html

Here is the #RStats #ggplot code so you can visualize the #dataviz trends in your own city: gist.github.com/JEFworks/0c7...

I use #ggplot #gganimate #Rstats to visualize spatiotemporal trends in public ICE detention data.

Watch ICE detention increase over time: more detainees (bigger dots), more non-criminals (blue → red), and more jails far from the border in 2025.

We also created an interactive website so doctors and scientists can easily explore our research data and use it to advance care and discovery.
