The adult form of pernicious anemia is most prevalent among individuals of either Celtic (ie, English, Irish, Scottish) or Scandinavian origin. In these groups, 10-20 cases per 100,000 people occur per year.

Pernicious anemia is reported less commonly in people of other racial backgrounds. Although the disease was once believed to be rare in Native American people and uncommon in black people, its incidence in these groups now appears to be higher than previous estimates suggested. Indeed, it is now apparent that pernicious anemia occurs more commonly in all racial and ethnic groups than was previously recognized.
