Data Interpretation IssuesThe are several variables collected on birth certificates which may be used to measure a mother's pregnancy history and family size. *Parity is the total number of live-born infants born prior to the current pregnancy. *Gravid is the total number of pregnancies including the current one. This includes pregnancies which resulted in miscarriages, fetal deaths, ectopic pregnancies, induced abortions, selective reductions, and live births. Multiple births count as one pregnancy. *Previous births now living and previous births now dead are also measures of pregnancy history and family size.
DefinitionParity is the total number of live-born infants born prior to the current pregnancy. It does not include the child(ren) of this pregnancy or any adoptions. Each child in a multiple pregnancy is counted separately and in the order of delivery.
