I don't think the data couldn't be useful, I just don't think it's worth it. The first problem is how will you collect this data? Self report? Assigned by the government based on your parents? DNA test? Who will you give this data to? What will you do with the conclusions? Say for Covid-19, will you make rules stricter for some ethnicities? Or prioritize them for vaccines? How do you even know how correct this data is? There's a big correlation between ethnicities, wealth and social customs. Or do you want to give the researchers also information about that? For me all the answers on those questions are negative. I see no way to do this in an ethical way. We already know there are issues with equality, employment etc of some ethnicities, I think collecting statistics on it will only make the racists in our society believe stronger in their views. I don't believe we can stop racism by introducing more (positive) racism.
