Definitions: Live births weighing less than 1,500 grams (3.4 pounds).
The data reflect the mother’s place of residence, not the place where the birth occurred. Births of unknown weight were not included in these calculations. Puerto Rico and Virgin Islands are not included in the U.S. Average.
Data Source: Centers for Disease Control and Prevention, National Center for Health Statistics.
1990 through 2010 state-level estimates are from the National Center for Health Statistics (NCHS), National Vital Statistics Reports or can be accessed through the NCHS VitalStats system http://www.cdc.gov/nchs/VitalStats.htm.
Updated January 2013.
S – NCHS reporting standards not met. N.A. – Data not available.
Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
