In biology and medicine, gravidity and parity are the number of times a female has been pregnant (gravidity) and carried the pregnancies to a viable gestational age (parity).

Adolescent fertility correlates strongly with poverty in African nations. The highest rate of teenage pregnancy in the world—143 per 1,000 girls aged 15–19 years—is in sub-Saharan Africa.
