A genogram contains basic information found in family trees, such as each person's name, gender, birth date, and death date. Additional data includes education, occupation, significant life events, chronic illnesses, social behaviors, familial relationships, emotional relationships, and social relationships, to name a few. Some genograms additionally include details regarding family ailments such as alcoholism, depression, diseases, partnerships, and living arrangements. Because there are no restrictions on the sort of data that can be included, genograms can be rather diverse.
Genograms make it easy to spot and analyze trends in a person's family history that may have influenced their current circumstances.
