Note: This variable was derived from race and was not asked as a separate demographic question. At the time of SHHS Visit 1, race and ethnicity were collected together in a single question. This variable was derived later on when the datasets were prepared for deposition in Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC).

Harmonized by the NSRR team to align with TOPMed and BioDataCatalyst standards. Source: :race:
