Who's At Risk
Hives appear in people of all ages, of all races, and of both sexes.

Acute hives are most common in children and young adults, and chronic hives are more often seen in females, especially middle-aged women.

Hives are very common; it is estimated that up to 20% of the population may develop hives at some point in their lives.
