NCHS has released a new report that presents 2014 data on U.S. births according to a wide variety of characteristics.
Data are presented for maternal age, live-birth order, race and Hispanic origin, marital status, attendant at birth, method of delivery, period of gestation, birthweight,and plurality.
Birth and fertility rates are presented by age, live-birth order, race and Hispanic origin, and marital status.
- In 2014, 3,988,076 births were registered in the United States, up 1% from 2013.
- The general fertility rate rose slightly to 62.9 per 1,000 women aged 15–44, the first increase in the rate since 2007.
- The teen birth rate fell 9% from 2013 to 2014, to 24.2 per 1,000 females aged 15–19.
- Birth rates declined for women in their early 20s but increased for women aged 25–39.
- The total fertility rate (estimated number of births over a woman’s lifetime) rose slightly to 1,862.5 births per 1,000 women.
- The birth rate for unmarried women declined for the sixth straight year.
- The cesarean delivery rate declined to 32.2%.
- The preterm birth rate declined 1% to 9.57%, but the low birthweight rate was essentially unchanged at 8%.
- The 2014 twin birth rate was 33.9 per 1,000 births, a new high for the United States; the triplet and higher-order multiple birth rate dropped 5% to 113.5 per 100,000 total births.

A new NCHS report presents recent findings for 2013 on four maternal morbidities associated with labor and delivery—maternal transfusion, ruptured uterus, unplanned hysterectomy, and intensive care unit (ICU) admission—that are collected on birth certificates for a 41-state and District of Columbia reporting area, which represents 90% of all births in the United States.
Key Findings from the Report:
- Rates of maternal morbidity were higher for cesarean than vaginal deliveries—rates of transfusion (525.1 per 100,000) and ICU admission (383.1) were highest for primary cesarean deliveries, while rates of ruptured uterus (88.9) and unplanned hysterectomy (143.1) were highest for repeat cesarean deliveries.
- Higher rates of maternal morbidity for cesarean compared with vaginal deliveries were found for nearly all maternal age groups and for women of all races and ethnicities.
- Women with no previous cesarean delivery who had vaginal deliveries had lower rates for all maternal morbidities compared with those who had cesarean deliveries.
- Women with a previous cesarean delivery who labored and had vaginal birth generally had lower rates for most of the morbidities, but failed trials of labor were generally associated with higher morbidity than scheduled repeat cesarean deliveries, especially for ruptured uterus, which was seven times higher (495.4 per 100,000 compared with 65.6).

A new NCHS report explores trends in low-risk cesarean delivery at a national level, with particular focus on changes from 2009 through 2013. Trends are examined by state of residence, gestational age, age of mother, and race and Hispanic origin of mother. An earlier report based on birth certificate data, using a slightly different definition, explored low-risk trends from 1990 through 2003
Key Findings from the Report:
- The low-risk cesarean delivery rate reached a low of 18.4% in 1997 and then rose steadily to a high of 28.1% in 2009. The rate decreased from 2009 through 2013, reaching 26.9%. Declines were widespread during this time.
- Low-risk cesarean delivery rates were down for more than one-half of states.
- Rates declined for all term gestational ages (37 or more completed weeks); the largest decline was at 38 weeks, down 9%.
- Rates for all maternal age groups and race and Hispanic origin groups were also down. The largest declines were for women under 40 (6%–8%) and for non-Hispanic white women (6%); rates for these groups decreased at all term gestational ages.

The state known as “The Last Frontier” has the highest suicide rate and ranks 6th in accidents. Alaska also has mortality rates that are higher than the U.S. for the following causes: cancer, stroke, Alzheimer’s disease and influenza/pneumonia.
However, Alaska had the lowest rates in the country for low birthweight rate (6% of all births) and cesarean delivery rates (20.8% of all births). The state also ranks among the 10 lowest rates for heart disease mortality, with an age-adjusted death rate of 151.5.

NCHS released a new report called Births: Preliminary Data for 2012 that looks at births in the United States. U.S. data on births are shown by age, live-birth order, race, and Hispanic origin of mother. Data on marital status, cesarean delivery, preterm births, and low birthweight are also presented. Key Findings from the Report:
- The preliminary number of births for the United States in 2012 was 3,952,937, essentially unchanged (not statistically significant) from 2011; the general fertility rate was 63.0 births per 1,000 women age 15-44 years, down only slightly from 2011, after declining nearly 3 percent a year from 2007 through 2010.
- The number of births and fertility rate either declined or were unchanged for most race and Hispanic origin groups from 2011 to 2012; however, both the number of births and the fertility rate for Asian or Pacific Islander women rose in 2012 (7 percent and 4 percent, respectively).
- The birth rate for teenagers 15-19 years was down 6 percent in 2012 (29.4 births per 1,000 teenagers 15-19 years), yet another historic low for the nation, with rates declining for younger and older teenagers and for nearly all race and Hispanic origin groups.
- The birth rate for women in their early twenties also declined in 2012, to a new record low of 83.1 births per 1,000 women. • Birth rates for women in their thirties rose in 2012, as did the birth rate for women in their early forties. • The birth rate for women in their late forties was unchanged.
- The nonmarital birth rate declined in 2012 (to 45.3 birth per 1,000 unmarried women aged 15-44), whereas the number of births to unmarried women rose 1 percent and the percentage of births to unmarried women was unchanged (at 40.7 percent). • The cesarean delivery rate for the United States was unchanged in 2012 at 32.8 percent.
- The preterm birth rate fell for the sixth straight year in 2012 to 11.54 percent.
- The low birthweight rate also declined in 2012, to 7.99 percent.

The total U.S. cesarean delivery rate reached a high of 32.9% of all births in 2009, rising 60% from the most recent low of 20.7 in 1996. Since 2009, the U.S. cesarean delivery rate has not increased. NCHS’s report explores cesarean delivery rates by gestational age for 1996–2011, focusing on 2009–2011. Analysis is limited to singleton births; multiple births are nearly 2.5 times more likely to be delivered by cesarean.
Key Findings from the Report:
- Cesarean delivery rates decreased more than 5% among births at 38 weeks of gestation, but increased 4% among births at 39 weeks.
- Decreases in cesarean delivery rates for births at 38 weeks occurred for non-Hispanic white, non-Hispanic black, and Hispanic women, as well as for all maternal age groups.
- Increases in cesarean delivery rates for births at 39 weeks occurred among non-Hispanic white, non-Hispanic black, and Hispanic women, as well as for all maternal age groups.
- The cesarean delivery rate at 38 weeks decreased in 30 states; the cesarean delivery rate at 39 weeks increased in 23 states.

A report released yesterday from the National Center for Health Statistics showed that the cesarean rate rose by 53% from 1996 to 2007, reaching 32%, the highest rate ever reported in the United States. The 1.4 million cesarean births in 2007 represented about one-third of all births in the United States.
Although clear clinical indications often exist for a cesarean delivery, the short- and long-term benefits and risks for both mother and infant have been the subject of intense debate for over 25 years. Despite this, the rate continues to rise for women in all racial and ethnic groups, as well as for women of every age, as shown below.
