Births: Final Data for 2013

January 15, 2015

A new NCHS report presents 2013 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. Selected data by mother’s state of residence and birth rates by age and race of father also are shown. Trends in fertility patterns and maternal and infant characteristics are described and interpreted.

Key Findings from the Report:

  • A total of 3,932,181 births were registered in the United States in 2013, down less than 1% from 2012.
  • The general fertility rate declined to 62.5 per 1,000 women aged 15–44.
  • The teen birth rate fell 10%, to 26.5 per 1,000 women aged 15–19.
  • Birth rates declined for women in their 20s and increased for most age groups of women aged 30 and over.
  • The total fertility rate (estimated number of births over a woman’s lifetime) declined 1% to 1,857.5 per 1,000 women.
  • Measures of unmarried childbearing were down in 2013 from 2012.
  • The cesarean delivery rate declined to 32.7%.
  • The preterm birth rate declined for the seventh straight year to 11.39%, but the low birthweight rate was essentially unchanged at 8.02%.
  • The twin birth rate rose 2% to 33.7 per 1,000 births; the triplet and higher-order multiple birth rate dropped 4% to 119.5 per 100,000 total births.

Births in the United States, 2013

December 4, 2014

A new NCHS report presents 2013 final birth data on several key demographic and maternal and infant health indicators. Trends in the number of births, general fertility rates, age-specific birth rates, and cesarean delivery rates by race and Hispanic origin, as well as trends in preterm births by state and trends in twin births are explored, with special focus on the most current period, 2012–2013. A previous report presented 2013 preliminary data on selected topics. Data are from the annual national natality files, representing 100% of births to U.S. residents.

Key Findings from the Report:

  • There were 3.93 million births in the United States in 2013, down less than 1% from 2012 and 9% from the 2007 high. The U.S. general fertility rate was at an all-time low in 2013.
  • Birth rates dropped to record lows in 2013 among women under age 30 and rose for most age groups 30 and over.
  • The cesarean delivery rate declined 1% from 2012 to 2013, to 32.7% of births. This rate rose nearly 60% from 1996 to 2009, but was down slightly from the 2009 high.
  • The 2013 preterm birth rate was 11.39%, down 1% from 2012 and 11% from the 2006 peak. Declines in preterm rates since 2006 were reported across the United States.
  • The twin birth rate, which had been mostly stable for 2009–2012, rose 2% in 2013 to 33.7 per 1,000 births.
