The U.S. Centers for Disease Control and Prevention (CDC) curates CDCREC for use in coding race and ethnicity data.
The main purpose of the code set is to facilitate use of federal standards for classifying data on race and ethnicity when these data are exchanged, stored, retrieved, or analyzed in electronic form.
CDCREC includes a hierarchy of race terms and a hierarchy of ethnicity terms.
