Not to say there haven't been lots of abortions since 1970 (there have been way too many) - but - on what basis where these statistics compiled? The US Department of Abortions? No.
There is no accurate number. And not all abortions are the same. Consider - about 1/3 of all women miscarry for any given pregnancy. Commonly, when this occurs, the doctor recommends the woman go for a "D & C" (dilatation and curettage.) It can be used as a diagnostic tool, to clean the uterus after a miscarriage and as a form of abortion. Problem. D&C counts toward the abortion statistics. So - how many "abortions" are not abortions, but clean up after a natural miscarriage? Answer - nobody friggen KNOWS! But we do know the "abortion" statistics are "contaminated" by D&C statistics counting as abortions when many of these are post-miscarriage procedures.
There have been many miscarriages as well. I watched my daughter and my wife suffer the same. Nobody will ever convince me that their grief was not a Mother's grief for a lost baby. Ever.
Are you sure? Do you have a reference? If true, then there really aren't any abortion statistics.
