Abstract Objective To analyze the factors correlated with perinatal death so as to provide the basis for reducing the perinatal mortality. Methods A respective study was conducted with analysis of perinatal mortality monitoring data,birth defects data and the health status report of non-registered pregnant women from 2012 to 2016 in Taizhou. We compared the differences in the indexes of perinatal mortality,birth defects rate and the proportion of elderly pregnant women in different years,domicile place and regions. Results The perinatal mortality rate was 6.80‰,decreasing annually from 2012 to 2016（P<0.01）. The average perinatal mortality rate of floating population was 9.28‰,which is higher than the 5.64‰ rate of local population（P<0.01）. The proportion of elderly pregnant women was 10.30%,showing an upward trend（P<0.01）and the perinatal mortality of elderly pregnant women was 10.60‰,significantly higher than the total mortality（P<0.01）. The leading cause of perinatal death was birth defect and the defect rate of perinatal birth was 35.86‰,showing an upward trend（P<0.01） while the average mortality rate of birth defects was decreasing（P<0.01）. There were statistically significant differences（P<0.01）in perinatal mortality,birth defects,sex ratio and proportion of elderly pregnant women in different regions of Taizhou. Compared with the perinatal in local population,mother age,education background,maternal times and register time of pregnant women of the perinatal in floating population was significantly different（P<0.01）. Conclusion The perinatal mortality in Taizhou declined year by year. Elderly pregnant age,birth defects,and floating population are the main positive factors of perinatal mortality.
