While dolls are usually for children, they are also collected by adults, for remembering things from the past, their beauty, their historical importance or their financial value (being worth money). In ancient times, dolls were used as symbols of a deity (god), and played an important role in religious ceremonies and rituals.

Lifelike or anatomically correct dolls are used by health professionals, medical schools, and social workers to train doctors and nurses in different health procedures or to find out about cases of sexual abuse of children. Artists sometimes use jointed mannequins or ball-jointed dolls in drawing the human body. Action figures are types of dolls that represent superheroes and military people are particularly popular among boys. There are baby dolls, paper dolls, rag dolls, talking dolls, fashion dolls and many others.
