What is a genogram?
A genogram is a diagram of a family across at least three generations, drawn with standard symbols for each person, couple and child, with lines for how people relate and fills for health conditions. Below is a finished genogram of the Okafor family, followed by what a genogram includes, how it differs from a family tree and who uses one.

Person symbols
A square for a male and a circle for a female, with the birth year above and the age inside. The X through Samuel's square is for his death in 2018.
Couple line
Robert and Patricia's couple line has two slashes for their divorce in 1983.
Child lines
Amara, Tobi and Kemi are joined to their parents' couple line, oldest on the left.
Emotional bond
The two green lines between Amara and her aunt Ifeoma are a close bond.
Health condition
The green quarter is diabetes, which Ngozi and her son Emeka both have.
Key
Each person symbol, couple and child line, emotional bond and condition fill in the genogram has a row in the key, with a count beside each one.
What a genogram is
A genogram is drawn in a standard notation, with a symbol for each person, a line for each couple and a line from each couple to their children, one generation to a row. Clinicians also add how family members relate to each other, the health conditions and causes of death in the family, and events such as a divorce, a migration or a cutoff.
Most genograms include three generations, the index person, their parents and their grandparents, so that a pattern such as early heart disease or a divorce in each generation can be seen on one page. In the Okafor genogram above, Amara is the index person and is drawn with a yellow outline.
What is included in a genogram
A full genogram includes these parts:
- People. A square for a male, a circle for a female and a diamond for a person of unknown gender, with the birth year above the symbol and an X through it for a death, as on the genogram symbols chart.
- Couple and child lines. A line joins each couple, with slashes across it for a separation or divorce, and each child is joined to that line, oldest on the left. The relationship lines guide has every couple line.
- Emotional bonds. A line between two people for how they relate, such as close, distant or in conflict, or the cutoff line when contact has stopped.
- Health conditions. A colored fill in part of a person's symbol for each condition. These fills are the core of a medical genogram.
- Households. A dashed outline around the people who live together, as in the multigenerational household example.
- Notes. Short facts under a name, such as a cause of death or, on a career genogram, each relative's job.
- The key. A list of each person symbol, couple and child line, emotional bond and condition fill used in the genogram, explained on the genogram key page.
Genogram vs family tree
On a family tree you can find names, dates and who is descended from whom. A genogram has the same structure in a standard notation, with relationships, health conditions and life events added, so a reader can see how the family works as well as who is in it. The genogram vs family tree example has one family drawn both ways.
What genograms are used for
Family therapists use a genogram to look for patterns that repeat across generations, such as triangles, cutoffs and fused relationships, which are concepts from Bowen family systems theory. The guide to genograms in family therapy has more on their use in practice, and the page on genograms in marriage and family therapy has a 3 generation example.
Social workers draw genograms in assessments, at intake or in a child welfare case, to see who is in a client's family and who could offer support, often next to an ecomap of the services around the family. The page on genograms in social work has a kinship care example.
Nurses and physicians use a medical genogram to take a family health history and look for conditions that run in the family, such as heart disease, diabetes or cancer, and a medical genogram is also the usual assignment for nursing students. The page on genograms in nursing has a family health history example.
School, career and pastoral counselors use genograms to understand the family a client comes from. On a career genogram each relative's job is written under their name, and a cultural genogram has each person's heritage, religion and migration added. Students who draw a family systems genogram for coursework can start from the example on the page about genograms in psychology and counseling.
Where genograms come from
Genograms grew out of the family diagram that Murray Bowen used to follow emotional patterns across generations in his family systems theory. Monica McGoldrick and Randy Gerson standardized the notation in their 1985 book Genograms in Family Assessment, and most clinicians still follow its symbols and its three-generation default.
How a genogram is drawn
A genogram is drawn in layers, starting with the people and the couple and child lines, then the emotional bonds, health conditions and notes. Each step is described in the how to make a genogram guide, and in the free genogram maker you can draw one in your browser without an account and export it with its key.
Questions people ask
See every page in the genogram guideWhat is the purpose of a genogram?
Therapists, social workers, nurses and counselors draw a genogram to see a client's family structure, relationships and health history across three generations on one page. A pattern that repeats, such as divorce, heavy drinking or early heart disease, is easier to see there than in a written history.
Who created the genogram?
Monica McGoldrick and Randy Gerson standardized the genogram symbols in their 1985 book Genograms in Family Assessment, building on the family diagram Murray Bowen used in family systems theory. The book's fourth edition, Genograms: Assessment and Treatment (2020), is still the standard reference.
Is a genogram just a family tree?
No. A genogram includes the people and lines of a family tree, in a standard notation, together with how family members relate, their health conditions and events such as a divorce or a migration.
See one family drawn as a tree and as a genogramWhat is another name for a genogram?
Clinicians trained in Bowen family systems theory often call it a family diagram, which was the name Bowen used. Outside Bowen theory, it is called a genogram or a family genogram in most textbooks and courses.
What is a genogram in social work?
Social workers draw a genogram as part of an assessment, and many draw an ecomap of the services and people around the family next to it.
Genograms in social workWhat is the difference between a genogram and an ecomap?
A genogram is a diagram of a family across generations, and an ecomap is a diagram of one person or household and the systems around them, such as school, work, health care and friends. The two are often drawn together in an assessment.
