Abstract

Objectives

This report presents 2024 data on U.S. births by selected characteristics. Trends in fertility patterns and maternal and infant characteristics are described.

Methods

Descriptive tabulations based on birth certificates of the 3.63 million births registered in 2024 are shown for various maternal demographic and health characteristics; medical and healthcare utilization, including source of payment for the delivery; and infant health characteristics. Selected data by mother's state of residence and birth rates also are shown. Trends for 2010 to 2024 are presented for selected items and by race and Hispanic origin for 2016-2024.

Results

A total of 3,628,934 births occurred in the United States in 2024, an increase of 1% from the record low reported for 2023. The general fertility rate declined 1% from 2023 to 53.8 births per 1,000 females ages 15-44 in 2024. Birth rates declined for females ages 15-34 from 2023 to 2024, rose for women ages 40-44, and were unchanged for females ages 10-14 and women ages 35-39 and 45-49. The total fertility rate declined 1% to 1,599.5 births per 1,000 women in 2024, a record low. Birth rates declined for both unmarried and married women from 2023 to 2024. Prenatal care beginning in the first trimester declined to 75.5% in 2024. The percentage of women who smoked during pregnancy declined to 2.4%. The cesarean delivery rate increased by less than 1% to 32.4%. Private insurance as the source of payment for the delivery increased to 51.8% of births, while Medicaid deliveries declined to 40.2%. The preterm birth rate (10.41%) was unchanged from 2023; low birthweight births declined 1% (8.52%). The twin birth rate declined 2% in 2024 to 30.1 per 1,000 births; the triplet and higher-order multiple birth rate was 71.3 per 100,000 births compared with 73.8 for 2023.

Births: final data for 2001

Martin JA et al., 2003 Natl Vital Stat Rep

This report presents 2001 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal demographic characteristics including age, live-birth order, race, Hispanic origin, marital status, and educational attainment; maternal characteristics (medical risk factors, weight gain, tobacco, and alcohol use); medical care utilization by pregnant women (prenatal care, obstetric procedures, complications of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, abnormal conditions, congenital anomalies, and multiple births). Also presented are birth and fertility rates by age, live-birth order, race, Hispanic origin, and marital status. Selected data by mother's State of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. Descriptive tabulations of data reported on the birth certificates of the 4.026 million births that occurred in 2001 are presented. Denominators for population-based rates are derived from the 1990 U.S. census. As a result, rates are generally larger than would be the case if 2000-based estimates were used. The magnitude of the overestimate will vary by population subgroup; overestimates are likely greatest for those of Hispanic origin. The number of births, the birth rate, fertility rate, and total fertility rates all declined 1 percent in 2001. The teenage birth rate reached another historic low. Birth rates for women in their twenties declined slightly, whereas rates for women aged 30 to 44 years continued to rise. Births to unmarried women changed very little. Smoking by pregnant women was down again. Women were more likely to begin care in the first trimester of pregnancy (83.4 percent). The cesarean delivery rate rose for the fifth consecutive year to 24.4 percent; the primary cesarean rate was up 5 percent and the rate of vaginal births after a previous cesarean fell 20 percent. Preterm and low birthweight levels both rose for 2001. The twin birth rate continued to climb, and following 2 years of decline, the rate of triplet/+ births also increased.

Annual summary of vital statistics--2001

March of Dimes, 2001 Pediatrics

The number of births, the crude birth rate (14.5 in 2001), and the fertility rate (67.2 in 2001) all declined slightly (by 1% or less) from 2000 to 2001. Fertility rates were highest for Hispanic women (107.4), followed by Native American (70.7), Asian or Pacific Islander (69.4), black (69.3), and non-Hispanic white women (58.0). During the early to mid 1990s, fertility declined for non-Hispanic white, black, and American Indian women. Rates for these population groups have changed relatively little since 1995; however, fertility has increased for Asian or Pacific Islander and Hispanic women. The birth rate for teen mothers continued to fall, dropping 5% from 2000 to 2001 to 45.9 births per 1000 females aged 15 to 19 years, another record low. The teen birth rate has fallen 26% since 1991; declines were more rapid (35%) for younger teens aged 15 to 17 years than for older teens aged 18 to 19 years (20%). The proportion of all births to unmarried women remained about the same at one-third. Smoking during pregnancy continued to decline; smoking rates were highest among teen mothers. The use of timely prenatal care increased slightly to 83.4% in 2001. From 1990 to 2001, the use of timely prenatal care increased by 6% (to 88.5%) for non-Hispanic white women, by 23% (to 74.5%) for black women, and by 26% (to 75.7%) for Hispanic women. The number and rate of twin births continued to rise, but the triplet/+ birth rate declined for the second year in a row. For the first year in almost a decade, the preterm birth rate declined (to 11.6%); however, the low birth weight rate was unchanged at 7.6%. The total cesarean delivery rate jumped 7% from 2000 to 2001 to 24.4% of all births, the highest level reported since these data became available on birth certificates (1989). The primary cesarean rate rose 5%, whereas the rate of vaginal birth after a previous cesarean delivery tumbled 20%. In 2001, the provisional infant mortality rate was 6.9 per 1000 live births, the same as in 2000. Racial differences in infant mortality remain a major public health concern, with the rate for infants of black mothers 2.5 times those for infants of non-Hispanic white or Hispanic mothers. In 2000, 66% of all infant deaths occurred among the 7.6% of infants born low birth weight. Among all states, Maine and Massachusetts had the lowest infant mortality rates. The United States continues to rank poorly in international comparisons of infant mortality. The provisional death rate in 2001 was 8.7 deaths per 1000 population, the same as the 2000 final rate. In 2000, unintentional injuries and homicide remained the leading and second-leading causes of death for children 1 to 19 years of age, although the death rate for homicide decreased by 10% from 1999 to 2000. Among unintentional injuries to children, two-thirds were motor vehicle-related; among homicides, two-thirds were firearm-related.

Association Between Loss of Hospital-Based Obstetric Services and Birth Outcomes in Rural Counties in the United States

Kozhimannil KB et al., 2018 JAMA Free full text on PubMed Central

Hospital-based obstetric services have decreased in rural US counties, but whether this has been associated with changes in birth location and outcomes is unknown. To examine the relationship between loss of hospital-based obstetric services and location of childbirth and birth outcomes in rural counties. DESIGN, SETTING, A retrospective cohort study, using county-level regression models in an annual interrupted time series approach. Births occurring from 2004 to 2014 in rural US counties were identified using birth certificates linked to American Hospital Association Annual Surveys. Participants included 4 941 387 births in all 1086 rural counties with hospital-based obstetric services in 2004. Loss of hospital-based obstetric services in the county of maternal residence, stratified by adjacency to urban areas. Primary outcomes were county rates of (1) out-of-hospital births; (2) births in hospitals without obstetric units; and (3) preterm births (<37 weeks' gestation). Between 2004 and 2014, 179 rural counties lost hospital-based obstetric services. Of the 4 941 387 births studied, the mean (SD) maternal age was 26.2 (5.8) years. A mean (SD) of 75.9% (23.2%) of women who gave birth were non-Hispanic white, and 49.7% (15.6%) were college graduates. Rural counties not adjacent to urban areas that lost hospital-based obstetric services had significant increases in out-of-hospital births (0.70 percentage points [95% CI, 0.30 to 1.10]); births in a hospital without an obstetric unit (3.06 percentage points [95% CI, 2.66 to 3.46]); and preterm births (0.67 percentage points [95% CI, 0.02 to 1.33]), in the year after loss of services, compared with those with continual obstetric services. Rural counties adjacent to urban areas that lost hospital-based obstetric services also had significant increases in births in a hospital without obstetric services (1.80 percentage points [95% CI, 1.55 to 2.05]) in the year after loss of services, compared with those with continual obstetric services, and this was followed by a decreasing trend (-0.19 percentage points per year [95% CI, -0.25 to -0.14]). In rural US counties not adjacent to urban areas, loss of hospital-based obstetric services, compared with counties with continual services, was associated with increases in out-of-hospital and preterm births and births in hospitals without obstetric units in the following year; the latter also occurred in urban-adjacent counties. These findings may inform planning and policy regarding rural obstetric services.

Triplet births in the United States. An epidemic of high-risk pregnancies

Keith LG et al., 2002 J Reprod Med

To more precisely understand the changes in triplet births in recent years. Analysis of recent government and medical publications pertaining to triplets. Triplet births are at much greater risk than singletons of poor birth outcomes. More than 9 of 10 triplet births are born preterm (< 37 completed weeks of gestation) as compared with < 1 of 10 singleton infants. The average weight of a triplet newborn (1,698 g) is one-half that of a singleton newborn (3,358 g). The infant death rate for triplet and other higher-order multiple births is 12 times higher than that for singletons (93.7 as compared with 7.8 infant deaths per 1,000 live births). Based on their frequency of preterm birth, low birth weight and infant death rate, it is appropriate to characterize all triplet pregnancies as high risk.

Societal cost of nine selected maternal morbidities in the United States

O'Neil SS et al., 2022 PLoS One Free full text on PubMed Central

To estimate the cost of maternal morbidity for all 2019 pregnancies and births in the United States. Using data from 2010 to 2020, we developed a cost analysis model that calculated the excess cases of outcomes attributed to nine maternal morbidity conditions with evidence of outcomes in the literature. We then modeled the associated medical and nonmedical costs of each outcome incurred by birthing people and their children in 2019, projected through five years postpartum. We estimated that the total cost of nine maternal morbidity conditions for all pregnancies and births in 2019 was $32.3 billion from conception to five years postpartum, amounting to $8,624 in societal costs per birthing person. We found only nine maternal morbidity conditions with sufficient supporting evidence of linkages to outcomes and costs. The lack of comprehensive data for other conditions suggests that maternal morbidity exacts a higher toll on society than we found. Although this study likely provides lower bound cost estimates, it establishes the substantial adverse societal impact of maternal morbidity and suggests further opportunities to invest in maternal health.
