There is a fascination with multiple pregnancies and multiples in our culture and many others. With the rise in the numbers of multiples, particularly twins, there are many questions that are commonly asked—like what are the terms used to describe multiple births?

A Simple Chart of Multiple Birth Terms

  • one baby - singleton
  • two babies - twins
  • three babies - triplets
  • four babies - quadruplets or quads
  • five babies - quintuplets or quints
  • six babies - sextuplets
  • seven babies - septuplets
  • eight babies - octuplets

Twins are More Common Than Triplets or More

According to the United States National Vital Statistics Report, there are approximately 33.9 sets of twins born for every 1,000 live births and 113.5 sets of triplets or more per 100,000 births.

In other words, twins are a lot more common (about 3 percent of all live births) versus a pregnancy with three or more babies (about 0.1 percent of all live births). This may surprise some people, considering the number of multiple births seen in the media or on reality television shows.

A Word From Verywell

Whether you, your partner, your friend or a loved is expecting multiple babies or you're just fascinated with multiples, there is a lot more to learn about multiple pregnancies—like how a multiple pregnancy develops or how it is different in terms of maternal and fetal risks than a singleton pregnancy.
