This appears to have a slight pro-Democratic tilt overall, but I do not think it's meaningful, especially given the limits of the data we're working with.
It has the equivalent of the following number of majority+plurality districts by racial group:
White: 284+27
Black: 27+14
Hispanic: 47+13
API: 10+7
"The equivalent" because with multi-winner districts, majority is not the relevant threshold. A group has the equivalent of a majority district if they are above the threshold for a seat, and a plurality district if they are below the threshold but closer than any other group.
As always, remember that these are not the actual districts that would be drawn if the Fair Rep Act passed. They're just samples. But proportional representation works - you'd get similar results under any reasonable set of districts.
3. Instead of each Rep having their own district, states would divide into larger multi-winner districts, each electing 3, 4, or 5 Reps proportionally. That's what these maps show.
