What is the difference between the Cohort Module and the Infant Mortality Module?
In the Live Birth/Infant Death Cohort Module the numerator consists of deaths to infants born in 1999 whether the death occurred in 1999 or 2000. As compared to the Infant Mortality module, where the numerator consists of all infant deaths occurring in 1999 that have been linked to their corresponding birth certificates, whether the birth occurred in 1998 or in 1999. The denominator for both files is the 1999 birth file, which contains all South Carolina Resident births occurring in 1999.
