Pityriasis rosea is a common skin condition characterized by a distinctive rash that usually begins with a single large patch, called a herald patch, followed by multiple smaller spots. The demographics most commonly affected by pityriasis rosea are young adults, particularly those in the age range of 20 to 30 years. Although females may have a slight predominance in some studies, the gender difference is not as significant as the age correlation.

The choice identifying young adults aged 20-30 as the most affected demographic reflects the broader understanding of the condition's typical presentation. Despite some representation among children and other age groups, the incidence peaks in young adulthood, making this group the more accurate answer.

Understanding the demographic factors allows healthcare providers to better recognize and diagnose the condition in their patient population, highlighting the importance of age over gender alone in this scenario.
