Genograms are used in a variety of fields, such as medicine, psychology, social work, genealogy, genetic research, and education.

Additional data may include education, occupation, major life events, chronic illnesses, social behaviors, nature of family relationships, emotional relationships, and social relationships. Some genograms also include information on disorders running in the family, such as alcoholism, depression, diseases, alliances, and living situations.
