In recent years, the infant mortality rate in Suzhou has continued to decline. In 1986, it was only 13.3‰. In order to correctly evaluate infant deaths in Suzhou, a special survey was conducted. The survey method was based on a stratified cluster sampling method for women of the most childbearing age. The composition of the industry investigated the pregnancy outcomes of pregnant women in 1985 and 1986 in several units. The infants whose live births were reported (in the investigation or the cause of death report) were investigated one by one. The gestational age and birth weight of the normal infants were also investigated.
