Description The linked birth and infant death data set is a valuable tool for monitoring and exploring the complex interrelationships between infant death and risk factors present at birth. In the linked birth and infant death data set the information from the death certificate is linked to the information from the birth certificate for each infant under 1 year of age who dies in the United States, Puerto Rico, The Virgin Islands, and Guam. The purpose of the linkage is to use the many additional variables available from the birth certificate to conduct more detailed analyses of infant mortality patterns. The linked files include information from the birth certificate such as age, race, and Hispanic origin of the parents, birthweight, period of gestation, plurality, prenatal care usage, maternal education, live birth order, marital status, and maternal smoking, linked to information from the death certificate such as age at death and underlying and multiple cause of death. Linked files are available for the data years 1983-91 and 1995-2002. Future data years will be available annually. Linked file data were not produced for the 1992-94 data years. Differences Between
