Birth Defects in the U.S. 2025
Birth defects continue to be a critical public health concern in the United States in 2025, affecting 1 in every 33 newborns, which equates to roughly 120,000 infants each year. These defects—which can be structural (such as cleft palate or congenital heart defects) or functional (including metabolic or developmental disorders)—often lead to long-term disabilities, emotional strain on families, and significant healthcare burdens. Despite advances in medical science and improved prenatal care, birth defects remain the leading cause of infant mortality, responsible for approximately 20% of all infant deaths nationwide. Their persistence reflects the complex mix of genetic, environmental, and lifestyle-related risk factors that continue to influence fetal development.
The current landscape of birth defects in the U.S. showcases both progress and challenges. Prevention strategies such as folic acid supplementation have led to a marked decline in neural tube defects, while improvements in prenatal screening and pediatric surgery have enhanced the survival rates of children born with conditions like congenital heart defects—of whom over 85% now live into adulthood. However, racial disparities, rising maternal age, and risk factors like obesity and diabetes continue to impact outcomes unevenly. With an estimated $2.6 billion in annual healthcare costs linked to treating birth defects, the urgency for continued public awareness, early detection programs, and equitable healthcare access remains at the forefront of maternal and child health initiatives in 2025.

The birth defects landscape in the U.S. in 2025 reveals a complex interplay of genetics, environment, and maternal health factors. Heart defects remain the most common category, affecting a large proportion of newborns with structural anomalies. Notably, male infants are more likely to be affected by specific defects—an observation backed by years of CDC research into sex-linked vulnerability during fetal development. A key risk factor continues to be maternal age, as women over age 35 face a significantly increased risk of having a child with chromosomal or structural anomalies. Fortunately, preventive efforts have shown measurable success—50–70% of neural tube defects like spina bifida can be prevented with adequate folic acid intake before and during early pregnancy.
Beyond biological factors, research in 2025 has deepened our understanding of genetic and environmental contributions to birth defects. According to CDC analysis, around 15–25% of cases can now be attributed to identifiable genetic causes, while 10–15% are linked to environmental exposures, including certain medications, infections, or harmful substances encountered during pregnancy. A striking 30% of affected babies are born with multiple defects, adding complexity to diagnosis and treatment. The economic impact is equally significant—birth defects cost the U.S. healthcare system billions of dollars annually, underscoring the need for continued investment in preventive care, early screening, and support services for affected families.

Clubfoot is by far the most common condition in this category, occurring in 1 in 536 births and affecting 6,850 babies annually. This condition involves the foot being twisted inward and downward, but with early intervention using casting techniques like the Ponseti method, most children achieve normal foot function and appearance.
Omphalocele and Gastroschisis are serious abdominal wall defects that occur at rates of 1 in 2,064 and 1 in 2,439 births respectively, affecting 1,779 and 1,506 babies annually. These conditions involve the intestines and other abdominal organs protruding outside the body and require immediate surgical intervention after birth. Diaphragmatic hernia, occurring in 1 in 3,214 births with 1,143 cases annually, involves a hole in the diaphragm that allows abdominal organs to move into the chest cavity, potentially causing serious breathing problems. Limb reduction defects, the least common at 1 in 4,021 births with 914 cases annually, involve incomplete formation of arms or legs, requiring ongoing orthopedic care and often prosthetic devices.
Eye Defects Statistics in the US 2025
| Eye Defect Type | Prevalence Rate | Annual Cases |
|---|---|---|
| Anophthalmia/Microphthalmia | 1 in 5,078 births | 723 cases |
Eye defects, while less common than other categories of birth defects, still represent a significant challenge for affected families. Anophthalmia and Microphthalmia occur in 1 in 5,078 births, affecting 723 babies annually. Anophthalmia is the complete absence of one or both eyes, while microphthalmia involves underdeveloped eyes that are smaller than normal. These conditions can range from mild vision impairment to complete blindness.
The impact of these eye defects extends beyond vision problems to include cosmetic concerns and potential psychological effects on both children and families. Treatment often involves the use of ocular prosthetics to improve appearance and may include vision therapy and special education services. While the prevalence of these conditions is relatively low compared to other birth defects, the specialized care required makes them particularly challenging for families to navigate. Early intervention and support services are crucial for helping children with these conditions develop to their full potential and integrate successfully into educational and social environments.
Chromosome Defects Statistics in the US 2025
| Chromosome Defect Type | Prevalence Rate | Annual Cases |
|---|---|---|
| Down Syndrome (Trisomy 21) | 1 in 643 births | 5,713 cases |
| Trisomy 18 | 1 in 3,336 births | 1,101 cases |
| Trisomy 13 | 1 in 6,967 births | 527 cases |
Chromosome defects represent a significant category of birth defects caused by abnormalities in chromosome number or structure. Down Syndrome (Trisomy 21) is the most common chromosomal condition, occurring in 1 in 643 births and affecting 5,713 babies annually. This condition, caused by an extra copy of chromosome 21, results in intellectual disability, distinctive facial features, and increased risk of certain medical conditions including heart defects and gastrointestinal problems.
Trisomy 18 and Trisomy 13 are much more severe chromosomal conditions with significantly higher mortality rates. Trisomy 18 occurs in 1 in 3,336 births affecting 1,101 babies annually, while Trisomy 13 occurs in 1 in 6,967 births affecting 527 babies annually. Both conditions involve severe intellectual disability, multiple organ system abnormalities, and poor prognosis, with many affected infants dying within the first year of life. The relatively high prevalence of Down Syndrome compared to other chromosomal conditions reflects both its compatibility with life and the increased awareness and diagnostic capabilities for this condition. These statistics underscore the importance of genetic counseling and prenatal screening programs that help families make informed decisions about their pregnancies.
Stomach and Intestine Defects Statistics in the US 2025
| Stomach/Intestine Defect Type | Prevalence Rate | Annual Cases |

| Esophageal Atresia | 1 in 4,167 births | 882 cases |
| Rectal and Large Intestinal Atresia/Stenosis | 1 in 2,220 births | 1,654 cases |
Stomach and intestine defects, while less common than some other categories, represent serious conditions that require immediate medical intervention. Rectal and Large Intestinal Atresia/Stenosis is the more common condition, occurring in 1 in 2,220 births and affecting 1,654 babies annually. This condition involves blockage or narrowing of the rectum or large intestine, preventing normal bowel function and requiring surgical correction.
Esophageal Atresia occurs in 1 in 4,167 births, affecting 882 babies annually. This condition involves incomplete development of the esophagus, the tube connecting the mouth to the stomach, making normal feeding impossible and requiring emergency surgical intervention. Both conditions significantly impact a newborn’s ability to feed and digest food properly, often requiring multiple surgeries and ongoing medical care. The specialized nature of these conditions means that affected infants typically require care at major medical centers with pediatric surgical capabilities. Early diagnosis and prompt treatment are crucial for optimal outcomes, and most children with these conditions can achieve normal digestive function with appropriate medical and surgical management.
