For the United States as a whole (top part of chart), infants in these health centers have a lower percentage of infants born with low birth weight than is the case in the population as a whole. This is the case whether the areas are urban or rural.

For particularly deprived populations, such as African Americans (bottom part of chart), the same is the case, even though low birth weight is more common in these areas.

These findings indicate a reduction in both relative as well as absolute inequity in low birth weight between more advantaged and less advantaged population groups.
