You already calculate the economic impact of the loss of workers, you could reframe the detention rates based on that. Any way to obviously state, “more is worse,” is a good start.
One other suggestion would be to include, somewhere, an image or oral account of detention conditions.
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.
