Average Birth Weight in the US 2025
Understanding birth weight patterns provides crucial insights into maternal and infant health across the United States. Birth weight serves as one of the most important indicators of newborn health and development, influencing immediate medical care needs and long-term health outcomes. The Centers for Disease Control and Prevention (CDC) through the National Center for Health Statistics (NCHS) continuously monitors these vital statistics to guide public health initiatives and healthcare policies.
The latest data reveals significant patterns in birth weight distribution across different demographic groups and geographic regions. Healthcare providers, policymakers, and expecting parents rely on this information to understand trends, identify at-risk populations, and implement appropriate interventions. Birth weight classifications help medical professionals determine necessary care protocols, with low birth weight infants requiring specialized attention and monitoring. These statistics reflect broader maternal health trends, access to prenatal care, and socioeconomic factors that influence pregnancy outcomes across American communities.

Understanding Birth Weight Categories and Their Implications in the US 2024
The data reveals critical patterns in how American babies are distributed across birth weight categories. The low birth weight rate of 8.58% represents a concerning continuation of elevated rates compared to historical benchmarks from the 1980s and early 2000s. This percentage translates to approximately 310,813 infants born in 2024 weighing less than the crucial threshold of 2,500 grams (5 pounds 8 ounces). Medical research consistently demonstrates that babies born below this weight face significantly higher risks of immediate health complications, including respiratory distress, feeding difficulties, temperature regulation problems, and increased susceptibility to infections.
The very low birth weight category, affecting 1.36% of births or roughly 49,268 infants, represents the most vulnerable population requiring intensive neonatal care. These babies weighing less than 1,500 grams (3 pounds 4 ounces) face substantially elevated risks of developmental delays, chronic health conditions, and require extended hospitalization in neonatal intensive care units. The rate has remained relatively stable since declining from peaks observed between 2005-2007, yet continues to strain healthcare resources and impact families across the nation. Within the moderately low birth weight range of 1,500-2,499 grams, approximately 261,545 babies were born, representing 7.22% of all births. These infants typically require special care but face better prognoses than their very low birth weight counterparts, though they still experience elevated health risks compared to normal weight newborns.
Low Birth Weight Rates by Race and Ethnicity in the US 2025
| Race/Ethnicity Group | Low Birth Weight Rate 2024 | Very Low Birth Weight Rate 2024 | Total Births 2024 |
|---|---|---|---|

Racial and Ethnic Disparities in Birth Weight Across the US 2024
The disparities in birth weight outcomes across racial and ethnic groups represent one of the most persistent health inequities in American maternal and infant health. Non-Hispanic Black mothers experience a low birth weight rate of 14.80%, more than double the rate observed among non-Hispanic White mothers at 7.04%. This translates to approximately 69,968 Black infants born at low birth weight in 2024 compared to roughly 125,339 White infants. The disparity becomes even more pronounced in the very low birth weight category, where Black infants face a rate of 3.02% compared to 1.08% for White infants, representing nearly triple the risk. These differences persist across socioeconomic levels and reflect complex interactions of factors including stress, discrimination, access to quality prenatal care, underlying health conditions, and environmental exposures.
Hispanic mothers showed a low birth weight rate of 7.92%, affecting approximately 77,770 infants in 2024, positioning them between White and Black populations. The Hispanic community of 982,253 births represents a substantial portion of American births, and their outcomes reflect diverse subpopulations with varying risk profiles. Asian mothers demonstrated a rate of 8.60%, slightly higher than White mothers, with approximately 19,500 infants born at low birth weight. American Indian and Alaska Native populations experienced a rate of 8.20%, while Native Hawaiian and Pacific Islander mothers showed 7.50%. These statistics underscore the critical need for culturally competent prenatal care, addressing social determinants of health, reducing maternal stress, and ensuring equitable access to comprehensive healthcare services across all communities.
Preterm Birth Rates and Birth Weight Correlation in the US 2024
| Gestational Age Category | Preterm Rate 2024 | Associated Low Birth Weight Risk | Number of Births 2024 |
|---|---|---|---|
| Early Preterm (Under 34 weeks) | 2.72% | Very High (90%+ low birth weight) | Approximately 98,537 |
| Late Preterm (34-36 weeks) | 7.69% | Moderate to High (40-60% low birth weight) | Approximately 278,564 |
| Total Preterm (Under 37 weeks) | 10.41% | Varies by gestational age | Approximately 377,101 |
| Early Term (37-38 weeks) | 29.84% | Lower risk but elevated | Approximately 1,081,046 |
| Full Term (39-40 weeks) | 54.94% | Lowest risk | Approximately 1,990,113 |
Data Source: CDC National Center for Health Statistics, Provisional Data for 2024
The Critical Connection Between Gestational Age and Birth Weight in the US 2024
Preterm birth represents the single most significant risk factor for low birth weight, with the preterm birth rate of 10.41% in 2024 remaining essentially unchanged from 2023. This rate translates to approximately 377,101 babies born before completing 37 weeks of gestation, with the majority requiring specialized medical attention and facing elevated health risks. The relationship between gestational age and birth weight follows a predictable pattern, with babies born earlier typically weighing less and facing compounded health challenges. Early preterm births occurring before 34 weeks, affecting 2.72% of births or roughly 98,537 infants, carry the highest risk of very low birth weight and associated complications including respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and long-term developmental challenges.
Late preterm births between 34-36 weeks account for 7.69% of deliveries, representing approximately 278,564 babies who may appear healthy but face subtle developmental delays and increased medical needs compared to full-term infants. The 2024 late preterm rate of 7.69% represents one of the highest levels recorded since 2007, when national obstetric estimate data became available. These babies often weigh between 2,000-2,500 grams, placing many in the low birth weight category while others fall just above the threshold. The distribution of term births shows 29.84% occurring at early term (37-38 weeks), a percentage that has increased in recent years, while 54.94% reach full term at 39-40 weeks, the optimal window for birth associated with the best health outcomes and normal birth weights typically ranging from 3,000-3,600 grams.
State-by-State Low Birth Weight Variations in the US 2024
| Geographic Region | States with Highest LBW Rates | Estimated LBW Rate Range | States with Lowest LBW Rates | Estimated LBW Rate Range |

Data Source: CDC National Center for Health Statistics, State-Level Birth Data 2023-2024 (estimates based on recent trends)
Geographic Variations in Birth Weight Outcomes Across the US 2024
Geographic location significantly influences birth weight outcomes, reflecting regional differences in healthcare access, socioeconomic conditions, racial and ethnic composition, and public health infrastructure. Southern states consistently demonstrate the highest low birth weight rates, with Mississippi, Louisiana, Alabama, and Arkansas experiencing rates between 10.5% and 12.0%, substantially above the national average of 8.58%. These elevated rates correlate with higher preterm birth rates, greater prevalence of maternal health conditions including hypertension and diabetes, limited access to comprehensive prenatal care in rural areas, and higher proportions of populations experiencing socioeconomic disadvantages. Mississippi particularly struggles with maternal and infant health indicators, reflecting systemic challenges in healthcare delivery and social determinants of health.
Northeastern and Western states typically demonstrate more favorable birth weight distributions, though significant variations exist within regions. Vermont, New Hampshire, and Maine consistently report among the lowest low birth weight rates at 6.5% to 7.0%, benefiting from better healthcare access, higher rates of prenatal care utilization, and more favorable socioeconomic indicators. Pacific Northwest states including Oregon, Washington, and Idaho similarly show rates in the 6.8% to 7.3% range. California, despite having one of the largest and most diverse populations with 401,515 births in 2024, maintains a rate around 8.0%, slightly below the national average. Urban-rural disparities within states add another layer of complexity, with metropolitan areas generally showing better outcomes than rural communities where healthcare access remains limited, specialist care requires extensive travel, and socioeconomic challenges persist.
Maternal Age and Birth Weight Patterns in the US 2024
| Maternal Age Group | Birth Rate per 1,000 Women 2024 | Estimated LBW Risk | Number of Births 2024 | Key Characteristics |
|---|---|---|---|---|
| Under 20 years | 12.7 (ages 15-19) | Elevated (9-10%) | 137,020 | Higher preterm risk, less prenatal care |
| 20-24 years | 56.7 | Moderate (8-9%) | 610,548 | Improving outcomes with proper care |

| 40-44 years | 12.8 | Elevated (9-11%) | 141,204 | Higher multiple birth and complication rates |
| 45+ years | 1.1 | High (11-13%) | 10,929 | Significantly elevated risks |
Data Source: CDC National Center for Health Statistics, Provisional Data for 2024
How Maternal Age Influences Birth Weight Outcomes in the US 2024
Maternal age represents a critical factor influencing birth weight outcomes, with both younger and older mothers facing elevated risks compared to women in their prime reproductive years. Teenage mothers ages 15-19, who delivered 137,020 babies in 2024 at a rate of 12.7 births per 1,000 females, experience higher rates of low birth weight estimated at 9-10%. These elevated risks stem from biological immaturity, inadequate prenatal care utilization, nutritional deficiencies, continued physical growth competing with fetal development, and socioeconomic factors including poverty, limited education, and lack of social support. The teen birth rate continues its decades-long decline, dropping 3% from 2023 and representing 69% lower than rates observed in 2007, yet those who do give birth face significant challenges.
Women ages 30-34 represent the largest group of mothers with 1,110,643 births at a rate of 95.4 per 1,000 women, and generally experience favorable birth weight outcomes with rates around 7-8% when receiving adequate prenatal care. This age group benefits from greater financial stability, higher education levels, better healthcare access, and established careers allowing for comprehensive prenatal care. However, mothers ages 40-44 who delivered 141,204 babies face elevated low birth weight risks of 9-11% due to increased rates of pregnancy complications including gestational diabetes, hypertension, placental problems, and chromosomal abnormalities. The birth rate for this group at 12.8 per 1,000 women has risen almost continuously since 1985, reflecting delayed childbearing trends. Women 45 and older, while representing just 10,929 births at a rate of 1.1 per 1,000 women, face the highest risks with low birth weight rates estimated at 11-13%, along with substantially elevated rates of preterm birth, cesarean delivery at 48%, and pregnancy complications.
Cesarean Delivery Rates and Birth Weight Considerations in the US 2024
| Demographic Group | Total Cesarean Rate 2024 | Low-Risk Cesarean Rate 2024 | Change from 2023 | Associated Factors |
|---|---|---|---|---|
| National Average | 32.4% | 26.6% | +0.1% (total) | Steady increase since 2019 |
| Non-Hispanic Black | 37.5% | 31.5% | +0.5% | Highest cesarean rate |
| Non-Hispanic White | 31.1% | 25.6% | Unchanged | Below national average |
| Hispanic (All Races) | 32.2% | 25.9% | +0.2% | Near national average |
| Non-Hispanic Asian | 34.4% | 30.1% | +0.2% | Elevated rates |
| Mothers 40+ years | 48.1% | N/A | +0.4% | Age-related increase |

Cesarean Delivery Trends and Their Impact on Birth Outcomes in the US 2024
The cesarean delivery rate of 32.4% in 2024 represents a continued upward trend from the 2019 low of 31.7%, affecting approximately 1,173,346 births. This rate positions the United States among countries with higher cesarean rates globally, raising concerns about overuse of surgical delivery and associated maternal and infant health implications. While cesarean delivery can be lifesaving when medically indicated, including cases of fetal distress, abnormal positioning, placental complications, or maternal health conditions, rising rates suggest factors beyond medical necessity may be influencing delivery decisions. These include practice patterns, liability concerns, maternal preferences, scheduling convenience, and previous cesarean deliveries creating higher likelihood of repeat procedures.
The low-risk cesarean rate of 26.6% measures surgical deliveries among first-time mothers with singleton, term, vertex (head-first) pregnancies—situations where vaginal delivery typically carries fewer risks. This rate remaining at 26.6% unchanged from 2023 indicates that approximately one in four women with the most favorable conditions for vaginal delivery undergo cesarean section. Non-Hispanic Black women face the highest cesarean rate at 37.5%, up from 37.0% in 2023, with their low-risk rate of 31.5% also substantially exceeding other groups. These disparities reflect complex factors including higher rates of medical complications, implicit bias in healthcare delivery, differing practice patterns across hospital systems serving diverse populations, and structural racism affecting medical decision-making. Asian women show elevated rates at 34.4% with low-risk rates of 30.1%, while Hispanic and White women experience rates closer to or below the national average. Maternal age strongly influences cesarean likelihood, with mothers 40 and older experiencing rates of 48.1%, nearly double that of younger mothers.
Prenatal Care Access and Birth Weight Outcomes in the US 2024
| Prenatal Care Timing | Percentage of Mothers 2023 | Associated Birth Outcomes | Estimated Impact on LBW |
|---|---|---|---|
| First Trimester Care | 76.1% | Optimal outcomes, early intervention | 6.5% – 7.5% LBW rate |
| Second Trimester Care | Approximately 16% | Moderate outcomes, delayed intervention | 9% – 10% LBW rate |
| Third Trimester/No Care | 7.0% | Poor outcomes, missed interventions | 15% – 20% LBW rate |
| Adequate Care (Non-Hispanic White) | 82.4% | Best access and outcomes | Lowest LBW rates |
| Adequate Care (Non-Hispanic Black) | 66.3% | Significant access barriers | Highest LBW rates |
| Adequate Care (Hispanic) | 68.9% | Moderate access challenges | Intermediate LBW rates |

The Critical Role of Prenatal Care in Birth Weight Outcomes Across the US 2024
Prenatal care access and timing represent modifiable factors significantly influencing birth weight outcomes, yet substantial disparities persist across demographic groups. In 2023, 76.1% of mothers began prenatal care in the first trimester, declining from 77.0% in 2022 and representing the lowest percentage since comparable national data became available in 2016. This translates to approximately 2,737,547 mothers receiving early care while roughly 859,470 mothers experienced delayed or no prenatal care. Early prenatal care initiation enables timely identification and management of maternal health conditions, nutritional counseling, screening for infections and complications, monitoring fetal growth, and intervention when problems arise—all factors that influence birth weight and overall pregnancy outcomes.
Late or no prenatal care, affecting 7.0% of mothers or roughly 251,721 women in 2023, associates with dramatically elevated risks of poor birth outcomes including low birth weight rates estimated at 15-20%, more than double the national average. Racial and ethnic disparities in prenatal care access mirror disparities in birth weight outcomes. Non-Hispanic White mothers achieved 82.4% first-trimester care initiation compared to just 66.3% for Black mothers and 68.9% for Hispanic mothers. These gaps reflect multiple barriers including insurance coverage limitations, geographic access challenges particularly in rural and underserved urban areas, cultural and linguistic barriers, discrimination and mistrust of healthcare systems, and socioeconomic factors limiting ability to take time from work or arrange childcare for appointments. Native Hawaiian and Pacific Islander women face the most significant barriers with only 48.6% beginning first-trimester care and 22.4% receiving late or no care, correlating with their elevated adverse birth outcome rates.
Multiple Birth Trends and Birth Weight Implications in the US 2024
| Multiple Birth Type | Rate per Births 2024 | Number of Births 2024 | Low Birth Weight Risk | Very Low Birth Weight Risk |
|---|---|---|---|---|
| Twin Births | 30.7 per 1,000 | Approximately 111,216 total infants | 56.3% | 9.4% |
| Triplet Births | 69.2 per 100,000 | Approximately 2,507 infants | 95.1% | 34.5% |
| Quadruplet+ Births | 4.1 per 100,000 | Approximately 148 infants | 98.4% | 82.3% |
| Singleton Births | N/A | 3,482,971 | 7.0% | 1.1% |
| All Multiple Births | Approximately 3.1% | Approximately 113,871 total infants | High to Very High | Significantly Elevated |
Data Source: CDC National Center for Health Statistics, Final Data for 2023 with 2024 estimates
Multiple Births and Their Profound Impact on Birth Weight Statistics in the US 2024
Multiple births exert disproportionate influence on low birth weight statistics despite representing only approximately 3.1% of all births, contributing substantially to elevated rates of preterm delivery and low birth weight. The twin birth rate of 30.7 per 1,000 births declined 2% from 2023, continuing a downward trend from the 2014 peak of 33.9, yet still remains 62% higher than rates observed in 1980. This translates to approximately 111,216 twin infants born in 2024, with an estimated 56.3% or roughly 62,595 babies born at low birth weight and 9.4% or approximately 10,454 twins born at very low birth weight. The average gestational age for twins is approximately 35-36 weeks compared to 39-40 weeks for singletons, with average birth weights around 2,300-2,500 grams compared to 3,200-3,400 grams for single births.
Triplet and higher-order multiple births, while rare at 73.8 per 100,000 births (down 6% from 2023), face the most severe risks with 95.1% of triplets born at low birth weight and 34.5% at very low birth weight. The approximately 2,507 triplet infants and 148 quadruplet or higher-order multiple infants born in 2024 require intensive medical care, prolonged hospitalization, and face significant developmental risks. The decline in higher-order multiples from the 1998 peak of 193.5 per 100,000 reflects changes in assisted reproductive technology practices, with clinicians transferring fewer embryos to reduce multiple pregnancy risks. However, the persistently elevated twin rate, driven partly by delayed childbearing (older mothers have higher natural twin rates) and continued use of fertility treatments, ensures that multiple births will continue influencing national birth weight statistics and placing demands on neonatal intensive care resources.
Socioeconomic Factors and Birth Weight Disparities in the US 2024
| Payment Source for Delivery | Percentage of Births 2023 | Associated LBW Patterns | Demographic Characteristics |
|---|---|---|---|
| Private Insurance | 51.0% | Lower LBW rates (6.5-7.5%) | Higher income, better prenatal access |
| Medicaid | 41.5% | Elevated LBW rates (9-10%) | Lower income, access barriers |
| Self-Pay/Uninsured | 4.4% | Highest LBW rates (12-15%) | Severe access limitations |
| Other Insurance | 3.2% | Variable outcomes | Military, tribal, government programs |
| Medicaid (Mothers <20 years) | 78.5% | Very high LBW risk | Compounded age and economic factors |
| Medicaid (Mothers 35-39 years) | 28.1% | Moderate LBW risk | Economic challenges at older age |
Data Source: CDC National Center for Health Statistics, Births: Final Data for 2023
Socioeconomic Determinants of Birth Weight Outcomes in the US 2024
Socioeconomic factors profoundly influence birth weight outcomes through multiple interconnected pathways including healthcare access, nutritional status, environmental exposures, chronic stress, and underlying health conditions. The source of payment for delivery serves as a proxy for socioeconomic status, with 51.0% of births covered by private insurance in 2023 (approximately 1,833,907 births) generally experiencing more favorable outcomes. These mothers typically have higher incomes, better education, stable employment with healthcare benefits, consistent access to prenatal care, ability to afford nutritious food, and lower exposure to environmental hazards—all factors promoting healthy fetal growth and normal birth weights.
Medicaid coverage for 41.5% of births (approximately 1,492,348 births) indicates lower socioeconomic status and associates with elevated low birth weight rates estimated at 9-10%, substantially above rates for privately insured mothers. Medicaid-covered mothers often face multiple challenges including food insecurity, housing instability, transportation barriers limiting healthcare access, residence in disadvantaged neighborhoods with environmental exposures, chronic stress from financial pressures, and higher rates of underlying health conditions. The 4.4% of births to uninsured/self-pay mothers (approximately 158,225 births) face the most severe access barriers, often receiving little or no prenatal care and experiencing low birth weight rates of 12-15% or higher. Age intersects with payment source, with 78.5% of teenage mothers relying on Medicaid compared to only 28.1% of mothers ages 35-39, reflecting how socioeconomic disadvantage compounds with biological age-related risks.
Smoking and Substance Use Impact on Birth Weight in the US 2024
| Maternal Behavior | Prevalence 2023 | Estimated Birth Weight Impact | LBW Risk Increase |
|---|---|---|---|
| Smoking During Pregnancy | 3.0% | Reduces birth weight 150-250 grams | Doubles risk (16-18% LBW) |
| Smoking (Non-Hispanic White) | 4.4% | Higher prevalence, significant impact | Major contributor to disparities |
| Smoking (Non-Hispanic Black) | 2.7% | Lower prevalence than White mothers | Still significant health impact |
| Smoking (Hispanic) | 0.8% | Lowest prevalence | Minimal population impact |
| Quit Before Pregnancy | 22.3% of smokers | Eliminates smoking-related risk | Returns to baseline risk |
| Smoking Ages 20-24 | 3.3% | Peak prevalence age group | Compounded with young age risks |
Data Source: CDC National Center for Health Statistics, Births: Final Data for 2023
Smoking and Substance Exposure Effects on Birth Weight Across the US 2024
Maternal smoking during pregnancy represents one of the most significant modifiable risk factors for low birth weight, with smoking mothers facing approximately double the risk of delivering low birth weight infants compared to non-smoking mothers. Despite dramatic declines over recent decades, 3.0% of mothers reported smoking during pregnancy in 2023, down 19% from 2022 and 58% from 2016, translating to approximately 107,881 mothers exposing their developing babies to tobacco smoke. Smoking during pregnancy restricts blood flow to the placenta, reduces oxygen delivery to the fetus, increases carbon monoxide exposure, and introduces numerous toxic chemicals—all mechanisms that impair fetal growth and typically reduce birth weight by 150-250 grams on average, often pushing babies from normal weight into the low birth weight category.
Racial and ethnic disparities exist in smoking rates, with 4.4% of non-Hispanic White mothers reporting pregnancy smoking compared to 2.7% of Black mothers and just 0.8% of Hispanic mothers. This pattern contrasts with the higher overall low birth weight rates among Black mothers, indicating that smoking represents just one of many factors influencing outcomes and that other determinants carry greater weight in explaining racial disparities. Smoking prevalence peaks among mothers ages 20-24 at 3.3% and ages 25-29 at 3.2%, declining among older mothers. Encouragingly, 22.3% of women who smoked in the three months before pregnancy successfully quit before or during early pregnancy, demonstrating that cessation efforts can succeed and eliminate smoking-related birth weight impacts. Substance use including alcohol and illicit drugs, though less completely captured in birth certificate data, similarly impairs fetal growth through various mechanisms including direct toxicity, nutritional deficiencies, placental insufficiency, and preterm delivery.
Future Outlook
The trajectory of birth weight statistics in the United States presents both challenges and opportunities for improving maternal and infant health outcomes. Current trends indicate that low birth weight rates around 8.6% are likely to persist or potentially increase slightly in coming years without significant interventions addressing underlying risk factors. The continued elevation of late preterm births at 7.7%, one of the highest rates since 2007, suggests ongoing challenges in preventing early deliveries and their associated impact on birth weight. Demographic shifts including continued delayed childbearing with more mothers over age 35, increasing prevalence of maternal obesity and chronic health conditions like diabetes and hypertension, and persistent racial and ethnic disparities all point toward sustained pressure on birth weight statistics. The decline in first-trimester prenatal care initiation to 76.1% raises particular concern, as early and consistent prenatal care represents one of the most effective strategies for optimizing pregnancy outcomes.
However, multiple promising developments offer pathways to improvement. Advances in maternal-fetal medicine continue enhancing ability to identify and manage high-risk pregnancies, with better ultrasound technology, fetal monitoring, treatment of maternal conditions, and neonatal care improving survival and outcomes even for very low birth weight infants. Growing recognition of racial and ethnic health disparities has spurred initiatives to address implicit bias in healthcare, improve culturally competent care delivery, and tackle social determinants of health through expanded Medicaid coverage, community-based interventions, and policy changes addressing housing, food security, and environmental justice. The dramatic success in reducing smoking during pregnancy from 7.2% in 2016 to 3.0% in 2023 demonstrates that targeted public health campaigns can achieve substantial progress on modifiable risk factors. Continued investment in research elucidating mechanisms underlying disparities, expansion of programs like home visiting services and group prenatal care, policy initiatives supporting paid family leave and workplace protections, and comprehensive approaches addressing the full spectrum of factors influencing pregnancy outcomes hold promise for reducing low birth weight rates and achieving health equity across all American communities in the years ahead.
