The mean age of mothers has increased from 2000 to 2014 for all birth orders, with age at first birth having the largest increase, up from 24.9 years in 2000 to 26.3 years in 2014. Increases in the average age for all birth orders were most pronounced from 2009 to 2014. In 2014, Asian or Pacific Islander mothers had the oldest average age at first birth (29.5 years), while American Indian or Alaska Native mothers had the youngest (23.1 years). Mean age at first birth increased in all states and the District of Columbia (D.C.) from 2000 to 2014, but D.C. (3.4 years) and Oregon had the largest increases (2.1 years).

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 4.022 million births that occurred in 2002 are presented. Denominators for population-based rates are derived from the 2000 U.S. census. Rates for 1991-2001 may differ from those published previously based on the 1990 U.S. census. There were 4,021,726 live births in 2002, essentially unchanged from 2001. The birth rate, fertility rate, and total fertility rates all declined 1 percent in 2002. The teenage birth rate dropped 5 percent, reaching another record low. The birth rates for women 20-24 years declined, whereas the rate for women 25-29 years was stable. The birth rate for women 30-34 years declined, but the rate for women 35-44 years continued to rise. Births to unmarried women changed very little. Smoking during pregnancy was down again. The timeliness of prenatal care continued to improve. The cesarean delivery rate climbed to the highest level ever reported in the United States (26.1 percent) and the rate of vaginal birth after previous cesarean plummeted 23 percent to 12.6 percent. Preterm and low birthweight levels both rose for 2002. The twin birth rate continued to climb, but the rate of triplet/+ births was down slightly.

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 4.09 million births that occurred in 2003 are presented. Denominators for population-based rates are derived from the U.S. 2000 census. In 2003 there were 4,089,950 live births reported in the United States, 2 percent more than the number in 2002. The crude birth rate (CBR) and general fertility rate (GFR) rose slightly. Childbearing among teenagers declined for the 12th straight year to another historic low. Birth rates for women aged 20-24 years also declined, whereas rates for women aged 25-44 years increased 2-6 percent, reaching highs not reported since the mid- to late 1960s. All measures of unmarried childbearing increased considerably in 2003, but smoking during pregnancy continued to decline. Timely initiation of prenatal care improved slightly. The cesarean delivery rate jumped another 5 percent to another all-time high, and the rate of vaginal birth after previous cesarean dropped 16 percent, an all-time low. Key measures of birth outcome-the percentages of preterm and low birthweight (LBW) births-rose. The twinning rate increased, but the rate of triplet and higher order multiple births was essentially stable.

This report evaluates the quality of selected medical and health data from the 2003 revision of the birth certificate by comparing birth certificate data with information abstracted from hospital medical records. A random sample of records for 600 births that occurred in 2010-2011 in State A, and a convenience sample of 495 births that occurred in State B in 2009 were reviewed. Birth certificate and hospital medical record data were compared for these categories: pregnancy history, prenatal care, gestational age, birthweight, pregnancy risk factors, obstetric procedures, onset of labor, source of payment, characteristics of labor and delivery, fetal presentation, method of delivery, abnormal conditions of the newborn, infant living, and infant breastfed. Levels of missing data, exact agreement, kappa scores, sensitivity, and false discovery rates are presented, where applicable. Exact agreement or sensitivity, was high for a number of items for both states (e.g., number of cesarean deliveries, cephalic presentation, cesarean delivery, and birthweight within 500 grams), but exact agreement or sensitivity was low or extremely low for both states for several items (e.g., total number of prenatal visits, previous preterm birth, meconium staining, and fetal intolerance of labor) (Figure 1). Levels of agreement or sensitivity for most items (e.g., prenatal care beginning in first trimester and source of payment-private insurance) were substantial or moderate. Data quality varied by state, and often, varied widely by hospital.

The percent change in rates for 1991-2000 is presented for the United States, and the change for 1991-99 is presented for States. Tabular and graphical descriptions of the trends in teenage birth rates for the Nation and each State, by age group, race, and Hispanic origin, are discussed. Birth rates for teenagers 15-19 years generally declined in the United States since the late 1950s, except for a brief, but steep, upward climb in the late 1980s until 1991. The 2000 rate (49 births per 1,000) is about half the peak rate recorded in 1957 (96 per 1,000). Still the U.S. rate is considerably higher than rates for other developed countries. During the 1990s rate declines were especially large for black teenagers. State-specific rates fell significantly in all States for ages 15-19 and 15-17 years, and in all but three States for ages 18-19 years. Overall the range of decline in State rates for ages 15-19 years was 11 to 36 percent. For teenagers 15-17 years, the range of decline by State was 13 to 43 percent. Reductions by State were largest for black teenagers 15-19 years, with rates falling 40 percent or more in seven States. The factors accounting for these declines include decreased sexual activity reflecting changing attitudes towards premarital sex, increases in condom use, and adoption of newly available hormonal contraception, implants, and injectables.
