Definitions for "Multiple birth"
The number of live births that resulted from multiple pregnancies (i.e., a twin, triplet, quadruplet, or quintuplet pregnancy) is reported in this document. Data presented in this report only indicate the number of births from the multiple pregnancy that were delivered alive, not the number of multiple pregnancies that occurred to Indiana women. Because some multiple pregnancies may result in both live births and stillborn fetuses, the total number of multiple births may not be an even multiple of the specified multiple pregnancy (e.g., an odd number of twins).
Delivery of more than one baby (twins, triplets etc.)
A multiple birth occurs when more than one baby is delivered at the same time.
