title: [Infant mortality and perinatal mortality in Poland in the eighties].
abstract: The dynamics of the changes in the level of infant mortality and perinatal mortality in Poland during 1980-89 by age and cause is presented. The statistical definitions concerning the perinatal period are used according to the World Health Organization's recommendations. There is stronger decline in postneonatal mortality rates then in neonatal rates during the eighties. The level of neonatal mortality rates (14.8 in 1989) and perinatal mortality rates (19.6 in 1989) is high comparing to the developed countries.
