Data element attributes
Collection and usage attributes
Guide for use:	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, should be included in the count of plurality. To be included, they should be recognisable as a fetus and have been expelled or extracted with other products of conception when pregnancy ended at 20 or more weeks gestation.
