The always informative Aaron Reichlin-Melnick brought the Deportation Data Project site to my attention. It does what you would think, providing aggregated data on detentions and deportations undertaken by the federal government.

Obtained directly from the government, the information is useful in part because it is broken down into a number of different categories. One can see, for example, the prior criminal histories (if any) of those arrested by ICE. Data are also broken down by state, date and disposition; if there’s information provided by the government, it’s indexed and available for perusal.

Granted, it’s a bit hard to peruse in its raw, tabular form. So I created a quick interactive, displaying monthly totals by state and category. Want to see arrests by criminal history in Delaware? Want to see the percentage of arrests in D.C. that targeted people with criminal histories? Go for it.

Following Reichlin-Melnick’s lead, I also broke out the data so that you can look at all arrests in a month or just those of people who weren’t already in law enforcement custody. (ICE will often arrest and deport people who were already detained by local law enforcement agencies.) You can play with the tool below.
