Friends:
What I don’t understand why this subject keeps popping up as stubbornly as it does. I haven’t heard much of a use case other than “I want to stratify XYZ by race”, and when that’s done folks stare at the percentages and learn - nothing.
The vast vast majority of our genetic material, which defines the our susceptibility to disease, is not distributed along racial lines. The couple genes switching melanine production high or low, or shape the eyes and nose length, appear important to our visual pattern recognition, but have nothing to do with outcomes. Tay-Sachs syndrome in Ashkenazi and Quebecians, and gastric cancer in Orientals are extremely rare exceptions in the overall distribution of things. When you really need to compare these racial subpopulations - please use the source values. If you in fact are after socioeconomic factors - there are better surrogates than that.
I guess I have an aversion against this insistence on racial differences.
