The prevalence of psoriasis is estimated to be between 500 and 4,600 cases annually per 100,000 people. Psoriasis usually affects individuals of the Caucasian race. Psoriasis tends to primarily affect Northern European and Southeast Asian countries.
Epidemiology and Demographics
- Worldwide, the prevalence of psoriasis ranges from a low of 500 cases per 100,000 persons to a high of 4,600 cases per 100,000 persons.
- The prevalence of psoriasis in the United States is 2,000 cases per 100,000 persons.
- Worldwide, the prevalence of psoriatic arthritis (PsA) ranges from a low of 100 cases per 100,000 persons to a high of 1,000 cases per 100,000 persons.
- Worldwide, 7,000 per 100,000 people with arthritis are affected by psoriasis.
- Worldwide, the incidence of psoriasis ranges from a low of 78.9 cases per 100,000 persons (United States) to 230 cases per 100,000 persons (Italy).
- Psoriasis has two peaks with regard to age. The mean age of the first peak is between 15 years to 25 years and the mean age of the second peak is between 55 and 60 years.
- Psoriasis tends to affect Caucasians more than other races, with a prevalence of 2,500 per 100,000 Caucasian persons in the United States, which is higher than other ethnic populations in the country.
- There is no gender predilection for psoriasis, although women are more severely affected than men once they have developed the disease.
