Collection and usage attributes

Guide for use:Help on this term

Plurality at birth is determined by the total number of live births and stillbirths that result from the pregnancy.

Stillbirths, including those where the fetus was likely to have died before 20 weeks gestation (including fetus papyraceous and fetus compressus), should be included in the count of plurality if recognisable as a fetus and expelled or extracted with other products of conception at 20 or more weeks gestation.
