The following section compares urban health to the national average for several indicators. Included are data on low and very low birth weight for infants born in U.S. cities with over 100,000 residents, and infant mortality among infants born in cities with more than 250,000 residents.
These comparisons indicate that the health status of infants living in large U.S. cities is generally poorer than that of infants in the Nation as a whole. In 2008, 8.7 percent of infants living in cities were born at low birth weight, compared to a national average of 8.2 percent. The infant mortality rate in 2006, the most recent year for which city-level data are available, showed a similar disparity, with a rate of 7.2 per 1,000 live births among infants in cities compared to 6.7 deaths per 1,000 live births for the Nation as a whole.
