Dr. Bela Ganatra:

There is no statistically significant difference in abortion rates based purely on the association of the restrictiveness of a country's laws. Abortion rates are, of course, significantly lower in the developed world and Europe - they have declined over the past 25 years - than they have in developing countries. It is not one on one because a number of factors determine the rates of abortion but when compared by legal status, we did not find that rates varied based on how restrictive laws were.
