Epidemiology

Keloids are only found in humans and occur in 1% to 16% of the population, with significant ethnicity-related differences.[2]​ Keloids are most common among Afro-Caribbean people, with an estimated incidence of 5% to 10%.[3]​ Some studies report an increased prevalence in Asian people compared with white people.[4][5]​​ However, the reported incidence is similar in Japan (0.1%) and England (0.09%).[3]​

It is thought that men and women are equally affected. The average age at onset is 10-30 years.[6]​
