Out of curiosity, what would be the driver for the decision to create local standard concepts vs. pushing for standardization of existing concepts? SNOMED already has codes for all of the race concepts mentioned in this thread - 4218447 works for Brazilian indigenous peoples and 4183595 works for Australian aboriginal peoples, no? Related to that, what is the rubric for deciding whether a concept is standard/non-standard? Apologies if this is clearly documented elsewhere - please feel free to tell me to go dig for my answer.
