Methodology Notes

A low-risk female is defined as one with a full-term (at least 37 weeks since LMP) singleton (not a multiple pregnancy), with a vertex fetus (head facing in a downward position in the birth canal). A description of the primary measurement used to determine the fetus’s gestational age, the interval between the first day of LMP and the birth has been published by NCHS.

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.
