City Data
Birth Weight
Low Birth Weight. Disorders related
to short gestation and low birth weight are the second leading cause
of neonatal mortality in the United States. In 2003, 114,085 babies
born to residents of U.S. cities with populations over 100,000 were
of low birth weight (weighing less than 2,500 grams, or 5 pounds
8 ounces); this represents a rate of 8.5 percent. The 2003 percentage
of urban infants born at low birth weight was 8 percent higher than
the National rate of 7.9 percent.
Very Low Birth Weight. Infants
born at very low birth weight (less than 1,500 grams, or 3 pounds
and 4 ounces) are at highest risk for poor health outcomes. In 2003,
1.6 percent of live births in cities with populations over 100,000
were of very low birth weight. This exceeded the National very low
birth weight rate by 14 percent.
