When it is said that abortion is significantly safer for women compared to childbirth in mainstream media articles, it is often followed by a reference to a scientific study called The Comparative Safety of Legal Induced Abortion and Childbirth in the United States by Elizabeth Raymond and David Grimes.
The study does claim:
The risk of death associated with child-birth is approximately 14 times higher than that with abortion.
However, people who are anti-abortion claim that the Raymond and Grimes study is seriously flawed.
The National Institute of Family and Life Advocates' article Abortion is Not Safer for Women Than Childbirth strongly criticizes the study:
...the data reported by abortion clinics to state health departments and ultimately to the CDC significantly under-represents abortion morbidity and mortality for several reasons
The article then lists these reasons:
Abortion reporting is not required by federal law and many states do not report abortion-related deaths to the CDC
Deaths due to medical and surgical treatments are reported under the complication of the procedure (e.g., infection) rather than the treatment (induced abortion)
Most women leave abortion clinics within hours of the procedure and go to hospital emergency rooms if there are complications that may result in death
Suicide deaths are rarely, if ever, linked back to abortion in states reporting of death rates
An abortion experience can lead to physical and/or psychological disturbances that increase the likelihood of dying years after abortion, and these indirect abortion-related deaths are not captured at all
The article cites the Guttmacher Institute's article Abortion Reporting Requirements as evidence that abortion is under-reported.
Funnily enough, some of what the Guttmacher article says shows that one previous point is false and misleading. For example, in the article it says:
States are not required to submit abortion data to the CDC, but the overwhelming majority do.
This shows that point 1) is false and misleading. Yes, it is not required, but that gives the impression that there’s no good reason to trust the CDC’s reporting.
Secondly, as per the Guttmacher article, it is not true that many states do not report abortion-related deaths to the CDC.
In one of the highlights in the Guttmacher article, it also states that
46 states and the District of Columbia require hospitals, facilities and physicians providing abortions to submit regular and confidential reports to the state.
That means only four states do not.
What about the other four points?
The website gives a source for these claims, but whenever I try to access the link I get a timeout. The anti-abortion website makes other claims related to the first point, but they have the same problems, and so are grossly misleading and inaccurate. Points 4 and 5 and extremely dubious, and the psychological hypothesis, if I'm not mistaken, is rejected by the scientific consensus on the matter.
I would be very pleased if someone could give me a source that backs up the other four claims, or provide a good argument or study that showed that abortion is significantly unsafe compared to childbirth, or a study that shows the opposite.
