Singleton births are births in pregnancies in which only one fetus is delivered live at any time during the pregnancy.

Gestational age can be classified as "preterm birth" when it occurs before 37 weeks of gestation, "early term" refers to births between 37 and 38 weeks, "full term" are between 39 and 40 weeks, and "late or post-term" encompasses 41 weeks and beyond.

Between 2014 and 2022, the distribution of singleton births by gestational age in the United States indicated that more than half of births were classified as full term. However, there was a slight but consistent decrease in the proportion of full-term births over the analyzed period. Conversely, early term births experienced a steady rise during the study period, increasing from approximately 24 percent in 2014 to nearly 30 percent by 2022. This statistic depicts the distribution of singleton births in the United States between 2014 and 2022, by gestational age.
