What is the incidence rate of twin gestations in the US?

The incidence rate of twin gestations in the United States is approximately 34 in 1000 births. This statistic reflects the overall increase in twin births over the past several decades, which can be attributed to various factors such as advanced maternal age and the use of fertility treatments that increase the likelihood of multiple gestations.

This figure is considered accurate among population studies and is used as a standard reference in the field of obstetrics and gynecology. Understanding this incidence rate is crucial for healthcare providers as it influences prenatal care, risk assessment, and management strategies for mothers expecting multiples.
