Calculate the risk of having a premature baby (<37 weeks and <32 weeks) based on the mother's age.

Premature delivery, delivery before 37 weeks of the pregnancy, is responsible for about 3 in 4 neonatal deaths. The risk of premature births depends on many factors including but not limited to whether you previously delivered prematurely, have twins, or you are older. Our calculations take into consideration data collected by US birth certificates between 2016-2018.
