One in 10 babies in the U.S. – nearly 374,000 infants – were born preterm in 2023, meaning before 37 weeks of pregnancy. More than 15% were very preterm, meaning they were born before 32 weeks. A full-term pregnancy lasts 40 weeks.
Florida’s rate is slightly higher, at about 1 in 9 babies born preterm. In an average week, 456 of the 4,257 babies born in the state will be preterm, and 75 of those will be very preterm.
