The purpose of this paper is to examine the relative importance of acc
ess to family planning and the motivation to restrict fertility in det
ermining contraceptive use in three countries that have led the fertil
ity transitions in their regions: Colombia, Tunisia, and Zimbabwe. A s
tructural equations model is estimated where endogenous fertility inte
ntions are allowed to affect contraceptive method use. Simulation meth
ods are then used to quantify the size of the impact of intentions and
access on method choice for the three countries. The results demonstr
ate that even after controlling for fertility intentions, family plann
ing program variables still have important effects in all three countr
ies.
