(ABC/WSYR-TV) -- A new study from the Centers for Disease Control and Prevention (CDC) shows that fewer infants are dying before their first birthday.
The infant mortality rate is the number of deaths of babies under one year old for every 1,000 live births.
After remaining virtually unchanged for five years (2000-2005), the infant mortality rate in the United States declined.
A CDC report found that infant deaths were down 12 percent between 2005 and 2011.
That drop occurred in four of the five leading causes of infant deaths: congenital malformations, low birth weight, sudden infant death syndrome and maternal complications.
The biggest decline – 16 percent – was among non-Hispanic black women. Historically, they have had the highest rate of infant mortality.
Non-Hispanic white women had a 12 percent decline and nine percent was among Hispanic women.
Despite the improvements, the United States still ranks 27th in the world for infant mortality.
