This report by the Childbirth Connection summarizes the best available research about the impact of the healthcare liability system on maternity care and policy strategies for improved functioning of the liability system in maternity care. A broad investigation of maternity care liability issues has not been carried out since the Institute of Medicine issued a report in 1989.
- The report finds that there are more claims for newborn than maternal injury, though childbearing women are more likely to sustain negligent injury, while receiving care in US hospitals. However, the rate of filing claims by or on behalf of those who experienced negligent injury, mother or newborn, is low, about 2%. Payment for damages goes to less than 1% of those with negligent injury, and most money awarded goes toward administrative and legal costs rather than plaintiffs.
- Furthermore, the report did not find evidence of the severe adverse impact this liability system is believed to have on premium affordability or evidence of extensive avoidance defensive practice or assurance defensive practice. The report goes on to propose solutions for deficiencies in the current liability system with the aim to alleviate professional stressors, improve care of women and newborns, and achieve better value for those who pay for maternity services. The report proposes evaluations of these strategies as well as abandoning efforts to advance policy strategies that lack empirical support and/or have potential for narrow impact.
From the report by the National Research Council & Institute of Medicine of the National Academies:
- "The United States spends much more money on health care than any other country. Yet Americans die sooner and experience more illness than residents in many other countries. While the length of life has improved in the United States, other countries have gained life years even faster, and our relative standing in the world has fallen over the past half century. What accounts for the paradoxical combination in the United States of relatively great wealth and high spending on health care with relatively poor health status and lower life expectancy?
- The report identifies a number of misconceptions about the causes of the nation’s relatively poor performance. The report describes multiple, plausible explanations for the U.S. health disadvantage, from deficiencies in the health system to high rates of unhealthy behaviors and from adverse social conditions to unhealthy environments. The panel painstakingly reviews the quality and limitations of evidence about all of the factors that may contribute to poor U.S. health outcomes. In this, and in earlier work the panel cites, many remediable shortcomings have been identified. Thus, the report advances an agenda for both research and action."
Key findings from this report from the CDC include:
- The pregnancy rate for U.S. women in 2009 was 102.1 per 1,000 women aged 15–44, the lowest level in 12 years; only the 1997 rate of 101.6 has been lower in the last 30 years.

This report provides extensive preliminary detail on deaths in 2011. It will eventually be superseded by a final version of the same report. Highlights include:
- On page 7, you will find basic facts about infant mortality (death from birth up to one year). Infant mortality showed a very slight decline from 2010 to 2011. Mortality among black infants was 2.2 times as high as among white infants (11.42 per thousand, compared to 5.11 per thousand).
- On page 8, you will find the top ten causes of infant mortality. It is interesting to think about which of these are and are not related directly to pregnancy and birth.
The revised birth certificate allows researchers to study even more trends in births in the United States. Check out this report using the revised certificate.
- Topics include prepregnancy obesity, receiving WIC, rates of smoking, deliveries covered by Medicaid, and the percentage of births resulting from infertility treatment.
The CDC released this report on Declines in State Teen Birth Rates by Race and Hispanic Origin: 2007-2011. Highlights include:
- "Teen birth rates fell at least 15% for all but two states during 2007–2011—the most recent period of sustained decline; rates fell 30% or more in seven states."
- "Declines in rates were steepest for Hispanic teenagers, averaging 34% for the United States, followed by declines of 24% for non-Hispanic black teenagers and 20% for non-Hispanic white teenagers."
This report by the CDC describes the recent decline in the U.S. infant mortality rate from 2005 through 2011. Highlights include:
- Changes in infant mortality rates over time are examined by age at death, maternal race and ethnicity, cause of death, and state.
- This data brief shows a decline in infant mortality rate by 12%, after plateauing in 2005.
- Since 2005, infant mortality rates for non-Hispanic Black women has declined 16%, 9% for Hispanic women, and declined most rapidly for some, but not all, Southern states.
- Despite these declines, states in the South still had among the highest rates in 2010. Infant mortality rates have also fallen for the five leading caused of infant death in 2011.
The CDC released this report on the Birth Rates for Teenagers in the United States in 2010. Highlights include:
- Though the teen birth rate in the United States remains one of the highest in the industrialized world, the birth rate for U.S. teenagers fell 9 percent from 2009 to 2010. When examining a consistent series of available rates, this resulting rate is the lowest in seven decades.
- The birth rate fell for teenagers in all age groups, in all racial and ethnic groups, and nearly all states. There remain disparities in birth rates across states and regions; however, some of the variation can be explained by the distribution of racial groups in each state.
- Without the fall in birth rate, an additional 3.4 million births to women 15-19 years of age would have occurred between 1992 and 2010.
- The decline is believed to have been influenced by pregnancy prevention messages directed to teenagers.
The National Center for Health Statistics released final data for the nearly 4 million births that occurred in the U.S. in 2010. Here are some highlights of this report:
- The number of U.S. births declined by 3% in 2010, with decreases occurring across nearly all ethnic and racial groups.
- While birth rates for women younger than 39 years declined from the previous year, including those of teenage girls (34.2 per 1,000), the rate for women 40-44 years continued to rise.
- Large disparities still exist between different states in terms of birth rates for teenage mothers. For example, in 2010 U.S. teenage birth rates ranged from 15.7 in New Hampshire to 55.0 in Mississippi.
- As in previous years, the vast majority of 2010 U.S. births occurred in hospital settings (98.8%) and were attended primarily by medical doctors (86.3%). Sixty-seven percent of out-of-hospital births occurred in a private residence (home), while 28% took place in a birthing center.
- For the first year since 1996, the cesarean section rate decreased reaching 32.8% (from 32.9% in 2009). Similarly to previous years, disparities exist between different racial and ethnic groups, with non-Hispanic black women being more likely to deliver by cesarean (35.5%) than non-Hispanic white (32.6%) and Hispanic women (31.8%). Great disparities also exist between different states, ranging from 22.6% in Alaska to 39.7% in Louisiana.
- While low birth weight remained stable at 8.15%, the preterm birth rate decreased to 11.99 percent, marking a decline for the fourth year in a row.
This report includes the most updated final data on deaths provided by the CDC, from 2010 data. Highlights include:
- It provides information about infant mortality by age (infant, neonatal, and postneonatal), sex, race, Hispanic origin, and cause (130 selected causes).
- From 2009 to 2010, the infant mortality rate decreased 3.8 percent, the neonatal mortality rate decreased 3.1 percent, and the postneonatal mortality rate decreased 5.4 percent.
- In 2010, Disorders related to short gestation and low birth weight, not elsewhere classified (second leading cause of infant death), decreased 5. 6 percent from 2009.
- The infant mortality rate did not change significantly in 2010 from 2009 for white infants but decreased 8.0 percent for black infants.
The CDC released this report on the Infant Mortality Statistics from the 2009 Period Linked Birth/Infant Death Data Set. This 2009 period linked data set contains information from the death certificate, which is linked to the birth certificate for each infant under the age of one who died in the 50 states, District of Columbia, Puerto Rico, Virgin Islands, or Guam. Highlights include:
- "The purpose of the linkage is to use the many additional variables available from the birth certificate to conduct more detailed analyses of infant mortality patterns."
- "This report presents infant mortality data by race and Hispanic origin of the mother, birthweight, period of gestation, sex of infant, plurality, maternal age, live-birth order, mother’s marital status, mother’s place of birth, age at death, and underlying cause of death."
- "The linked file is used to analyze and calculate infant mortality rates by race and ethnicity which are more accurately measured from the birth certificate."
This report covers the rising incidence of twins and higher multiples in the United States.
- Over the past 30 years, rates of twinning have gone up 76%, and are now at 33.3/1000.
- Every state saw increases in the rate of twins, although some dramatically more than others. The same is true across races and Hispanic origin, although the increase was less among Hispanic mothers. Similarly, rates increased in all age groups, but higher increases were seen in older mothers.
- The age distribution of mothers - more older women now have babies, and older women are more likely to have twins - accounts for about a third of the increase in twin births. Most of the rest is assumed to be due to treatment for infertility.
This report examines trends over time in home birth in the United States since 1990, using data from the National Vital Statistics System.
- The report provides information and graphs showing that while there has been an overall increase in home births between 1990 and 2009, most of the rise is due to non-Hispanic white women.
- Home birth rates among other groups declined overall since 1990, although in some subgroups the rates have gone up since the mid-2000s.
- The report also discusses:
- Geographic variation in home birth rates
- What kind of providers attend these births
- The risk profiles of women who deliver at home
A one-page reference sheet compiled by Childbirth Connection, this document provides comparisons of average charges by delivery facility type and delivery method for all U.S. births occurring between 2007 and 2009. This fact sheet was created using data made available through the U.S. Agency for Healthcare Research and Quality, HCUPnet, Healthcare Cost and Utilization Project. The complete dataset is available online at: http://hcupnet.ahrq.gov/
The CDC released this report on the racial and ethnic disparities in infant mortality in the United States based on the 2007 data. Highlights include:
- Its findings include a 2.4 times higher rate of infant mortality among non-Hispanic black women than among non-Hispanic white women, and a 1.6 times higher rate among American Indian and Alaska Native women than among non-Hispanic white women. Data for many more racial and ethnic groups is available in the report.
- The report also examines differences in the proximal causes of infant mortality between groups, finding that most excess mortality among non-Hispanic black infants is due largely to prematurity. However, the higher rates among American Indian and Alaska Native infants are due to mortality among term and near-term infants.
The CDC released this report on the final birth data from 2009. Highlights include:
- 4.13 million births occurred in the U.S. during 2009.
- Births decreased 3% from the previous year, with decreases among all racial and ethnic groups.
- Births also decreased among teenage mothers by 6%, reaching the lowest teenage birth rate (39 per 1,000) in seven years.
- While the preterm birth rate decreased in 2009, the rate of cesarean sections increased to 32.3%, as did the proportion of women with gestational diabetes or hypertension (41.2 per 1,000).
The CDC released this report on the final death data from 2008. Highlights include:
- It provides information about infant mortality by age (infant, neonatal, and postneonatal), sex, race, Hispanic origin, and cause (130 selected causes).
- It also includes trend data for infant mortality by race and sex back to 1940, and state-by-state (and territory) data on infant mortality by race.
The CDC released this report on the Infant Mortality Statistics from the 2007 Period Linked Birth/Infant Death Data Set. This 2007 period linked data set contains information from the death certificate, which is linked to the birth certificate for each infant under the age of one who died in the 50 states, District of Columbia, Puerto Rico, Virgin Islands, or Guam. Highlights include:
- In 2007, the infant mortality rate was 6.75 infant deaths per 1000 live births.
- The range in infant mortality was from 4.57 per 1000 live births for mothers of Central and South American origin to 13.31 for non-hispanic black mothers.
- A higher infant mortality was seen with male infants and infants born preterm or at low birthweight.
- The overall infant mortality rate was impacted by those infants with the lowest gestational ages and birthweights.
The CDC released this report in May 2010 on the final death data from 2007. Highlights include:
- This report contains the most recent US data on maternal mortality defined as those deaths occurring during or up to 42 days after pregnancy that were judged to be related to or aggravated by pregnancy or pregnancy management.
- A key population indicator of health, the US maternal mortality rate for this year was 12.7 deaths per 100,000 births.
- Like it does with infant mortality, the US population has dramatic racial disparities in maternal mortality.
- The report provides this data, as well as data about selected causes of maternal mortality and rates by Hispanic origin.
