  3. Methodology

    We expanded the SNOMED ethnicity codelist identifying 657 ethnicity SNOMED codes. By comparing the codelist to the ctv3 codelist, the primis codelist, and a codelist from GDPPR we grouped the codelist according to the 2001 census. Then we removed the codes that did not identify an ethnicity, leaving 599 codes.
