As a non-expert who cares about this issue, the "criminal/other" split is very clear and was the first thing I looked for.
This is very counter to the administration narrative that our country is teeming with foreign gang members, and it is presented in a chill, non-shrill, high credibility way. That's very helpful!
Some more explanation or breakdown on what types of "other" violations dominate (e.g. are these all just overstays?) might be nice, but the point is still well made. I would also like to see what percentage were felony charges/convictions if there's a significant percentage of misdemeanors.
I expect with the recent ICE funding boost and the hiring spree they're about to go on, the "criminal"/"other" ratio going to plummet as ICE climbs the s-curve. It will be very useful to have a live measure of that as it happens.
One meta point: I'm always shocked at how rare it is, for issues that are current and important in the public discourse, that someone makes a technically and visually competent, single-purpose website contributing to the debate. I have seen them to be extremely valuable on campaigns I've worked on, such as the campaign to stop the SOPA/PIPA site-blocking bills in 2011/2012, but it's so rare anyone makes one. Thank you for creating an exception to a generally disappointing rule!
ICE alleges these people have violated the civil code so calling them "violators" assumes guilt and comes across as inflammatory. Something like like "No Criminal Status" would be accurate and more neutral.
Personally, I'd call them "Productive Members of Society The Rest of Us Depend On."
Like it or not, this data is highly political. You can’t correctly interpret it in a vacuum.
This is only useful for in-group messaging.
You could collect oral accounts and invite people to submit them.
From the grapevine (and this makes sense because they're pushing into new numerical territory, and also don't care at all) the conditions are very crowded / harsh. You could also include accounts from family members about the kafkaesque absence of information, e.g. It's good to make the point that almost every number in this chart is a human, and a family and circle of friends, who harmed no one and is being severely harmed.
Also loans forgiven would be nice to see since ICE signups now get a $10K reduction. Not a large number but more to make a point.
Number of children separated from Families.
Number of US citizens illegally detained.
Number of lawsuits against ICE.
Cost of ICE vs each Detainee.
This also underplays the current cruelty of the US system, far out of proportion with any proper policing of immigration (which obviously reasonable people can argue about). So, I don't think you're wrong exactly, and you can play the victim if you want ("I know I will be downvoted", sad violin).
