Definition
A typical pregnancy last around 40 weeks. Babies that are born between 37 and 42 weeks of pregnancy are called full term. Babies that are born before 37 weeks of pregnancy are called premature. Babies that are born between 22 and 32 weeks of pregnancy are called very premature. About 12.5 percent of babies (more than half a million per year) in the United States are born prematurely. For reasons that are not fully understood, the rate of premature birth has increased by more than 30 percent since 1981.How We Calculated the Rates
| Numerator: | Number of live infant births occurring before 32 weeks of gestation during a specific time period. |
