SNOMED Ethnicity SNOMED CT

This is a codelist of all ethnicity codes which ever appear in TPP. SNOMED codes with a zero count are excluded from the codelist.

We are aware that some of the individual codes contained in this codelist are offensive and upsetting. Although these terms are outdated and no longer in routine use, it is necessary to include them in codelists due to the historic nature of the data that is being analysed.
