*Data in this table are constructed from survey questions 40 (When was your baby due?) and 42 (When was your baby born?)

~Due to low response rates in the later part of the year, the 2005 PRAMS tables only comprise data for January through August births.

#Use caution in interpreting cell sizes less than 50.
N = Cell Size, % = Percentage, C.I.(95%) = Confidence Interval (at 95 percent probability level).
The percentages shown are weighted percentages, designed to reflect the entire population of North Carolina women having a live birth.
