There is no single global count of mothers who die from postpartum depression each year, largely because these deaths are systematically undercounted. In the United States, suicide accounts for roughly 39% of combined homicide and suicide deaths among pregnant and recently postpartum people, totaling 886 suicides over an 18-year period from 2005 to 2022. That works out to about 49 deaths by suicide per year among this narrowly defined group. But the real number is almost certainly higher, and understanding why requires looking at how these deaths are tracked and what falls through the cracks.
What the U.S. Data Actually Shows
A national study reviewing CDC data from 2005 through 2022 found that 20,421 pregnant people died during that period. Of those deaths, 11% (2,293) were due to homicide and suicide combined. Breaking that down further, 886 were suicides. Homicide and suicide together rank as the leading cause of maternal death in the U.S., which surprises many people who assume hemorrhage or preeclampsia top the list.
About 1 in 8 women with a recent live birth report symptoms of postpartum depression, according to CDC surveillance. Perinatal mental health conditions, including postpartum depression and the rarer but more dangerous postpartum psychosis, are now recognized as a leading underlying cause of pregnancy-related deaths. Not every maternal suicide stems from postpartum depression specifically, but untreated or undertreated perinatal mood disorders are a major driver.
Why the True Number Is Higher
The World Health Organization’s official definition of a maternal death excludes deaths from intentional injury, poisoning (including drug overdose), and self-harm. That means a suicide by a woman suffering from postpartum depression is never classified as a maternal death under the standard international framework, even when her pregnancy clearly played a role. This single definitional choice removes an entire category of deaths from the most widely cited maternal mortality statistics.
Death certificates create another gap. Studies conducted before a pregnancy checkbox was added to U.S. death certificates found that as many as half of all maternal deaths could not be identified through cause-of-death information alone. Even after the checkbox was introduced, medical certifiers sometimes mark it incorrectly. The result is a messy dataset where some deaths are overcounted and others are still missed entirely.
The 886 suicides identified in the national study only captured deaths during pregnancy or within the first 42 days after delivery. Postpartum depression can develop or worsen well beyond that window. Research from the National Institute of Mental Health found that among women with suicidality, nearly 59% of diagnoses occurred in the year after giving birth. Deaths that happen at three, six, or nine months postpartum often fall outside the surveillance window, meaning they are never linked back to childbirth at all.
When Risk Is Highest
Suicidal thoughts and behaviors during the perinatal period are not evenly distributed across time. NIMH data shows that the year after birth carries higher risk than the year before: 59% of suicidality diagnoses among childbearing women appeared in the postpartum year, compared to 45% in the year before delivery (with some overlap, as about 4% of women experienced suicidality in both periods).
Postpartum psychosis, a rarer condition affecting roughly 1 to 2 out of every 1,000 deliveries, carries a significantly elevated risk of suicide. It typically emerges within the first two weeks after birth and involves hallucinations, delusions, or severe confusion. While postpartum depression develops more gradually and affects far more women, postpartum psychosis is responsible for a disproportionate share of the most acute crises.
Racial Disparities in Risk
Postpartum depression does not affect all mothers equally. About 1 in 5 American Indian/Alaska Native, Asian or Pacific Islander, and Black women report symptoms of pregnancy-related depression, compared to roughly 1 in 10 White women. Hispanic women report rates similar to White women, at around 12% versus 11%.
These gaps appear to be widening. Research among women in Southern California found that postpartum depression prevalence has grown over the past decade, with the steepest increases among Black and Asian and Pacific Islander women. The reasons are layered: women of color face greater barriers to mental health care, higher exposure to racism and chronic stress, and cultural barriers that can delay help-seeking. Racism and discrimination are now recognized in research as direct contributors to poor maternal mental health outcomes, not just background factors.
The Gap Between Prevalence and Deaths
Postpartum depression is common. Suicide from postpartum depression is rare in absolute terms. The vast majority of the roughly 500,000 U.S. women each year who experience postpartum symptoms will recover, especially with treatment. But “rare” in a population this large still translates to dozens of confirmed deaths annually in the U.S. alone, with the true figure likely higher once you account for deaths beyond 42 days postpartum, deaths misclassified on certificates, and overdoses that may be intentional but are recorded as accidental.
Globally, no reliable count exists. Many countries lack maternal mortality review committees, and the WHO definition’s exclusion of suicide from maternal death statistics means most nations have no systematic way to track these losses. What researchers do know is that perinatal mental health conditions are a leading underlying cause of pregnancy-related death wherever the data has been examined closely enough to look.
The honest answer to “how many mothers die from postpartum depression” is that we don’t fully know, and the systems designed to count maternal deaths were built in a way that ensures we won’t, at least not without significant changes to how these deaths are classified and tracked.
