Twin birth rates in the United States 1980-2023, by ethnicity
In the United States, non-Hispanic Black women currently have higher rates of twin births than any other ethnicity or race with **** per 1,000 live births being twins. There are two types of twins, identical and fraternal.

Fraternal twins, although born at the same time, are no more alike than siblings born at different times.Â
