In an interesting ( though faulty) study from the Charlotte Lozier Institute (anti-choice) in which the author gives reasons why women received late term abortions for reasons other than to protect their own life/health or fetal defect.  "Among women in the late-term abortion group, the most commonly cited reason for delaying the procedure was 'raising money for the procedure and related costs'.” they also cited "“difficulty securing insurance coverage,” “difficulty getting to the abortion facility,” and “not knowing where to go for an abortion”.  https://lozierinstitute.org/the-reality-of-late-term-abortion-procedures/ 

If you want to see why there is a problem with not knowing where to go and difficulty in getting to an abortion facility, then take a look at the % of counties without an abortion provider by state here:  https://en.wikipedia.org/wiki/Abortion_in_the_United_States_by_state 

Anti-abortion crowd efforts produce more late term abortions.
