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. 

Fetuses aborted before 20 completed weeks and less than 400 gramss are excluded. If the pregnancy commences as a twin pregnancy but one fetus is miscarried/aborted before 20 weeks and 400 grams, the plurality is single.

Code 1 Singleton
The total number of births resulting from this pregnancy is one.

Code 2 Twins

Code 3 Triplets
The total number of births resulting from this pregnancy is three.

Code 4 Quadruplets
The total number of births resulting from this pregnancy is four.

Code 5 Quintuplets
The total number of births resulting from this pregnancy is five.

Code 6 Sextuplets
The total number of births resulting from this pregnancy is six.

Code 8 Other

Comment 
Multiple pregnancy increases the risk of complications during pregnancy, labour and delivery and is associated with higher risk of perinatal morbidity and mortality.
