A diagrammatic representation of Oliveros Allan's family relationship is shown below.
The health information about the families portrayed is contained in genograms. First, they comprise basic information common in family trees, such as each individual's name, gender, date of birth, and date of death. Education, occupation, key life events, chronic illnesses, social behaviors, type of familial relationships, emotional relationships, and social relationships are all examples of additional data. Some genograms also incorporate information on family-run problems like 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.
