Mortality, infant: The death of an infant before his or her first birthday.
The infant mortality rate is, by definition, the number of children dying under a year of age divided by the number of live births that year. The infant mortality rate is also called the infant death rate.
The infant mortality rate is an important measure of the well-being of infants, children, and pregnant women because it is associated with a variety of factors, such as maternal health, quality and access to medical care, socioeconomic conditions, and public health practices.
In the United States, about two-thirds of infant deaths occur in the first month after birth and are due mostly to health problems of the infant or the pregnancy, such as preterm delivery or birth defects. About one-third of infant deaths occur after the first month and are influenced greatly by social or environmental factors, such as exposure to cigarette smoke or problems with access to health care.
The infant mortality rate in the US, which was 12.5 per 1,000 live births in 1980, fell to 9.2 per 1,000 live births in 1990. However, in 1999 it was reported that "Over the past 8 years, the death rate among black infants has remained nearly 2.5 times that among white infants." (Pediatrics 104: 1229-1246, 1999.)
