The other thing this doesn't control for, aside from the physical factors you've mentioned, is the average # of people in a household, or the avg # of dwellings per building (apartments versus single-family homes, etc.). The last column would be interesting if it was death rate per X number of people infected. But then of course we really have no idea who's been infected, so that's not possible. EDIT: also, darker skinned people have honestly been, on average, less likely to be able to stay home. Construction, delivery, food prep, etc,— those folks have largely kept working and so increase their risk. Great local study in SF about this. In any event, you know I think your eye for data is great and helpful. I just don't think it should make white folk (like me) breathe a big sigh of relief. This virus is nasty.
since skin color is a topic, here is a warning to be careful on drawing conclusions.. https://www.nejm.org/doi/full/10.1056/NEJMp2012910 It is equally important, however, that in documenting Covid-19 racial disparities, we contextualize such data with adequate analysis. Disparity figures without explanatory context can perpetuate harmful myths and misunderstandings that actually undermine the goal of eliminating health inequities. Such clarifying perspective is required not just for Covid-19 but also for future epidemics. There are several key dangers of insufficient contextualization, but researchers, journalists, public health officials, and policymakers can take a few important steps to address them when discussing racial disparities, especially in the public sphere.
It's kind of weird to have this discussion about which groups are being hit hardest by COVID-19 and not explicitly call out poverty/income level as a major factor. (I know your edit addresses this to a degree.) I think when this is more comprehensively studied, we'll find that poverty/income level and all the increased risk factors for this group from baseline health, living conditions, ability to limit exposure because of work circumstance, etc will explain the disproportionate impact much better than "race".
It's turning into a very class based and divisive (boomer remover) epidemic. People who have the luxury of working from home usually take higher paychecks. Not sure how wall streets staying bubbly with unemployment numbers like they are, unless they think all the furloughed folk will shuffle back to their "replaceable" jobs...
