I'm glad you see my point. Race is a social construct. That construct changes over time. What use is this data without defining what is being measured? In the decision of Alvarez v Lemon Grove (1931) the judge refers to people of Mexican descent as 'one race of White people'. White wasn't a race in 1931. Greek, Slav and German were all different races of White people.

We do need to talk about race because there are racists in the world, but we need to be sure we all have the same understanding of the words we use.
