Number of live births in states that use the 2003 standard certificate of birth
Estimates were calculated with data supplied by the states that had adopted the 2003 version of the U.S. State Certificate of Live Birth. Trends over time cannot be evaluated until such time as all states provide data in the same format.
Twenty-two states had implemented the 2003 birth certificate as of January 1, 2007. The 22 revised states represent 53% of all U.S. births.
