Parity is typically recorded in a format known as the GTPAL system where:
G stands for Gravida (total number of pregnancies). T stands for Term births (births after 37 weeks). P stands for Preterm births (births between 20 and 37 weeks). A stands for Abortions (spontaneous or induced before 20 weeks). L stands for Living children.
For example, a woman with a GTPAL score of 3-1-1-1-2 has been pregnant three times, had one term birth, one preterm birth, one abortion, and has two living children.
