Prevalence of Psoriasis

Who Develops Psoriasis?

Psoriasis affects an estimated 3.0% of the adult population 20 years of age or older in the United States, or more than 7.5 million adults.
Approximately 600,000 adults in the United States live with undiagnosed psoriasis.
Psoriasis prevalence is similar between males (2.8%) and females (3.2%).
Prevalence appears to differ by race and ethnicity, although these estimates may be due to health disparities experienced by individuals with psoriasis – including disproportionate underdiagnosis of psoriasis and lower rates of utilizing dermatologic care among racial and/or ethnic minoritized individuals.
Whites have the highest prevalence of psoriasis (3.6%) followed by Asians (2.5%) and then Blacks (1.5%).
An estimated 1.9% of Hispanics have psoriasis.
Psoriasis prevalence increases with age, with individuals between the ages of 50 – 59 experiencing the highest prevalence of psoriasis (4.3%), followed by individuals 70 years of age or older (3.9%).
Among adults, individuals between the ages of 20 – 29 had the lowest prevalence of psoriasis (1.6%).
