To calculate the fetal death rate, which of the following should be in the denominator?

The denominator for calculating the fetal death rate should consist of the total number of live births and fetal deaths. This is because the fetal death rate is typically expressed as the number of fetal deaths per a certain number of total births (which includes both live births and fetal deaths).

Including total live births in the denominator allows for a more accurate reflection of the mortality rate concerning the total number of pregnancy outcomes. By adding fetal deaths to live births, one can accurately assess the incidence of fetal deaths within the context of all pregnancies that resulted in either a live birth or a fetal death. This comprehensive inclusion ensures that the calculation doesn't overlook the significance of fetal deaths in the overall reproductive outcome statistics.
