In referring back to the definitions in paragraph 3-2, the information is abbreviated as parity/gravidity.
For example, “0/1” means that a woman has not carried a pregnancy to viability (nullipara) and is pregnant for the first time (primigravida).
Table 3-1 below shows parity and gravidity using a five-digit system:
