Your quoted figure of less than 1% abortions for birth defect, rape, life of mother is wrong. Eptopic preganancies are from 1 to 2% of life threatening events. This does not even cover all the other reasonable needs for abortion. The link below gives details of many specific kinds of problems. I looked for statistics on various reasons for abortion. I did not find any specific lists, but from what I saw, I think your abortion statistics are for the world, not the US.

1. I did say that my 1% figure was decades old. That implies it's old information, perhaps not current information.
2. Has any state outlawed abortion in the case of protecting the life of the mother? I know Alabama did as a temporary legal measure to get their pro-life law to SCOTUS (and the legal-ease they tried to avoid was trying to make the case for protecting the life of the baby while at the same time saying the baby is sometimes expendable in hardship cases). Thus, now that Roe is overturned, Alabama's legislature is already working on changing the law to allow hardship case abortions. I believe all of the pro-life states are doing the same. Thus, it's a moot point to argue the "But what about" situations -- it's already in the works to allow those abortions in the near future.
