In 2004, 6,482 infants born to residents of cities in the United States with populations over 250,000 died in the first year of life. The infant mortality rate in U.S. cities was 7.4 deaths per 1,000 live births, which was higher than the rate for the Nation as a whole (6.8 per 1,000). Although the infant mortality rate in cities has consistently been higher than the rate nationwide, it has declined over the past decade, and the disparity in infant mortality rates between infants in cities and the Nation as a whole has decreased by 50 percent. Between 1990 and 2004, the infant mortality rate in cities has declined by nearly one-third, while the nationwide decline during the same period was 25.3 percent. Declines in infant mortality rates since 2000, however, have been relatively small for both cities and the population as a whole.
