Notes: All percentages are weighted. pdiff. indicates results of an F test of the null hypothesis that there is no difference between the National Survey of Family Growth (NSFG) (women ages 20–34 at LARC discontinuation) and the National Longitudinal Survey of Youth 1997 (NLSY97) estimates.

a

National Survey of Family Growth (NSFG), 2006–2010, 2011–2013, 2013–2015, and 2015–2017 cycles. LARC discontinuation occurred no more than three calendar years before the calendar year of the woman's survey interview.
