The prevalence of vitiligo is believed to be be-tween 0.5% and 2% of the world population on average, but local numbers may vary greatly. Large studies in China, India, and Denmark have found the prevalence to be 0.093%, 0.005%, and 0.38%, respectively. Gujarat, India is considered to have the highest prevalence in the world with 8.8% of the local people affected by vitiligo. Men and women are equally affected, but women are more likely to seek treatment. In most studies, 20% of vitiligo subjects report to having a first-degree relative suffering from vitiligo.

The mean age of onset is earlier in those patients having family history of vitiligo, which ranges from 7.7% to more than 50%. Vitiligo is significantly more prevalent in young women (≤ 30 years of age) than in young men. The peak occurrence in females occurs in the first decade of life.
Male peak prevalence is in the fifth decade of life. Vitiligo is more frequently diagnosed in spring and summer (64.4%).
