It is important to monitor the births occurring outside hospitals and to ascertain whether or not the actual place of birth was planned. If a jurisdiction is unable to record this data element for each baby in a multiple birth then the place of birth of the first-born baby should be recorded. |

| DSS specific information: Birth order is only assigned to births that are in scope for the Perinatal NMDS (i.e. births of at least 20 weeks gestation or 400 grams birthweight). In the case of multiple pregnancies, if one or more fetuses were removed from the mother's uterus before 20 weeks gestation, for example, by abortion (spontaneous, induced or fetal reduction), they are not considered in the assignment of birth order for any remaining fetuses that are born. For example, in a twin pregnancy, where one fetus is aborted before 20 weeks gestation, no birth order would be recorded for that twin. If the remaining twin is born and is in scope for the Perinatal NMDS, then their birth order would be recorded as Code 1 (Singleton or first of a multiple birth). If both twins are born and are in scope for the Perinatal NMDS, the first twin would be assigned a birth order of Code 1 (Singleton or first of a multiple birth) and the second twin would be assigned a birth order of Code 2 (Second of a multiple birth). In the case of multiple births, this data element should be recorded for each baby born. |

[4]
| 9999 | Not stated/inadequately described |
| DSS specific information: Weight is an important indicator of pregnancy outcome, is a major risk factor for neonatal morbidity and mortality and is required to analyse perinatal services for high-risk infants. In the case of multiple births, this data element should be recorded for each baby born. |
- | Gestational age | 695332 | Number
[2]
| | DSS specific information: The first day of the last menstrual period (LMP) is required to estimate gestational age, which is a key marker in pregnancy and an important risk factor for neonatal outcomes. Although the date of the LMP may not be known, or may sometimes be erroneous, estimation of gestational age based on clinical assessment may also be inaccurate. Gestational age is usually estimated based on available information on LMP and clinical assessment. In the case of multiple births, this data element should be recorded for each baby born.
