How common are postpartum mental health conditions?
Postpartum mental health conditions are common and treatable. About 1 in 5 birthing people experience a perinatal mood or anxiety disorder during pregnancy or the first year after birth (Postpartum Support International) — making these the most common complication of childbirth. Yet up to half of cases go undiagnosed, and with the right support, most mothers recover.
How widespread are perinatal mood and anxiety disorders?
They are the single most common complication of childbirth. Perinatal mood and anxiety disorders (PMADs) touch roughly 1 in 5 birthing people, and the figures below show just how common they are.
- About 1 in 5 women — and 1 in 10 men — may experience depression and anxiety during the perinatal period (Postpartum Support International).
- PMADs are the most common complication of childbirth, affecting roughly 1 in 5 birthing people during pregnancy or the first year postpartum (Policy Center for Maternal Mental Health).
- About 15–20% of new mothers in the US experience a PMAD (Policy Center for Maternal Mental Health).
- Postpartum depression diagnosis rates have nearly doubled, rising from 9.4% in 2010 to about 19% in recent years (Policy Center for Maternal Mental Health).
- Maternal anxiety disorders affect about 20% of women, with peak rates of roughly 25.5% during early pregnancy (Policy Center for Maternal Mental Health).
How many mothers actually get diagnosed and treated?
Far fewer than the number who need it. Up to half of cases are never noticed, and most mothers are never even screened — so the gap between who is affected and who gets care is wide. It also helps to know that this often does not start after birth.
- Up to 50% of PMAD cases go unnoticed or undiagnosed (Policy Center for Maternal Mental Health).
- Despite ACOG guidelines, fewer than 20% of women are screened for maternal depression (ACOG).
- Maternal depression often begins before birth: about 33% of episodes start during pregnancy and about 26% before pregnancy, with only about 40% beginning purely postpartum (Policy Center for Maternal Mental Health).
Who is affected most — and least likely to get care?
The burden does not fall evenly. Some mothers face higher rates and, at the same time, steeper barriers to treatment. Fathers are affected too. And cost remains a real wall for many families (see our postpartum therapy cost guide).
- Black and Latina mothers experience postpartum depression at rates up to 40% — nearly double the rate of White mothers — yet are up to 57% less likely to receive treatment (Policy Center for Maternal Mental Health).
- Women in rural communities are about 21% more likely to develop postpartum depression than those in urban areas (Policy Center for Maternal Mental Health).
- About 10% of new fathers also experience depression or anxiety, especially when their partner is affected (Postpartum Support International).
Why does untreated maternal mental illness matter?
Because the cost is measured in both lives and dollars. Untreated perinatal mood and anxiety disorders carry a heavy burden for mothers, babies, and families.
- Untreated PMADs carry an enormous burden — costing upwards of $32,300 per affected mother–child pair in medical and developmental impacts (Policy Center for Maternal Mental Health).
- Up to 20% of perinatal deaths are linked to suicide, which generally peaks between 9 and 12 months postpartum (Policy Center for Maternal Mental Health).
The hopeful part
Do mothers recover with treatment?
Yes. The most important point of all is that these conditions are treatable — and with the right support, most mothers get better.
- Perinatal mood and anxiety disorders are temporary and treatable with appropriate support (Postpartum Support International).
- Early identification matters: when up to half of cases go unnoticed, getting screened and connected to care is often the turning point (ACOG).
- Trauma-informed therapy with a perinatal specialist is a well-established part of recovery (Postpartum Support International).
What is the Postpartum Therapy Project doing about this gap?
We close the gap between “needs help” and “gets help.” The Postpartum Therapy Project funds a full year — 26 bi-weekly sessions — of specialized postpartum therapy at $0 to mothers who qualify, matches each mom with a vetted, trauma-informed perinatal therapist, and runs peer support groups.
If you're a mom, learn about free postpartum therapy and who qualifies. If you work with new mothers, you can refer a mom in a few minutes.

Frequently asked questions
- How common is postpartum depression?
- About 1 in 5 women — and 1 in 10 men — may experience depression and anxiety during the perinatal period, according to Postpartum Support International. Perinatal mood and anxiety disorders (PMADs) are the most common complication of childbirth, affecting roughly 1 in 5 birthing people during pregnancy or the first year postpartum, and about 15–20% of new mothers in the US experience a PMAD.
- Is postpartum depression only a postpartum problem?
- No. Maternal depression often begins before birth. About 33% of episodes start during pregnancy and about 26% start before pregnancy, with only about 40% beginning purely after birth. That is one reason the term "perinatal" matters — it covers pregnancy and the first year after.
- How many mothers go untreated?
- A large share. Up to 50% of PMAD cases go unnoticed or undiagnosed. Despite ACOG guidelines, fewer than 20% of women are screened for maternal depression — so many mothers are never identified, let alone treated.
- Do perinatal mood and anxiety disorders affect everyone the same way?
- No. The burden falls unevenly. Black and Latina mothers experience postpartum depression at rates up to 40% — nearly double the rate of White mothers — yet are up to 57% less likely to receive treatment. Women in rural communities are about 21% more likely to develop postpartum depression than those in urban areas, and about 10% of new fathers also experience depression or anxiety.
- Can postpartum depression and anxiety be treated?
- Yes. Perinatal mood and anxiety disorders are common and treatable, and with appropriate support most mothers recover. Specialized, trauma-informed therapy with a perinatal therapist is a well-established part of that support.
