This doesn’t seem accurate at all. The census itself doesn’t display this info, is it from their website? Race is self reported so I don’t get why a origin map is relevant. Also, the US census does not consider hispanic/Latino to be a racial category. Folks who select that option for ethnicity are ALSO asked to select race seperately.
Only thing that could make it better would be small icons showing the most notable goods transported on each. I can guess but I bet there would be some surprises
