† Total births at each gestational week served as the denominator for stillbirth and perinatal mortality rates (1), while live births at each gestational week constituted the denominator for early neonatal death rates (1). Stillbirth, early neonatal death and perinatal mortality rates (2) were calculated using fetuses-at-risk as the denominator (see text). All rates are expressed per 1,000. ‡ All gestational ages, including those <32 weeks and those with missing gestational age.
