In particular, the figure of 1% of abortions for cases of rape or incest is widely cited. However, it is probably exaggerated. If correct, it would imply that 15,600 abortions in 1987 were for such cases.[3] Since the FBI only reported 91,110 forcible rapes in the U.S. in that year[4], this would imply that one out of six rapes resulted in pregnancy--a result significantly at odds with medical research. Even if a significant underreporting of rape is assumed, the figure of 1% appears to be too high.
Some sources claim, on the basis of medical studies, that the total number of pregnancies resulting from rape each year is on the order of 200-500.[5] Even if all such pregnancies were aborted (which is not a valid assumption according to some analysts), this would still represent less than 0.1% of abortions.
