No, it doesn't. While that may possibly be the percentage of pregnancies that are lift threatening, there are four classes of pregnancies to consider:
“The 13/100K statistic implies that the ratio of #4 to #2 is about 13:100K. That does not imply that the ratios of #3 to #1, nor (#3+#4) to (#1+#2) are are similar.”
Yes, but since the everyone admits that the overwhelming majority of cases health isn’t the reason women get abortions, there is good reason to assume that the ratio of 3 to 1 would not be differ significantly from the ratio of 4 to 2.
But don’t believe me, check out the numbers. In Ireland, where abortion is illegal, the maternal mortality rate is a minuscule 2 per 100,000 birth.
Given the low frequency the matter actually comes into play, the maternal health risk issue is a complete red herring in the abortion debate. Brought up only to distract us from the real issue.
