Brucejoel, the article you cited noted:
In 1967 (DC note: i.e. just before the states began liberalizing their abortion laws), researchers confirmed this estimate by extrapolating data from a randomized-response survey conducted in North Carolina: They concluded that a total of 800,000 induced (mostly illegal) abortions were performed nationally each year
Snip
In deciding Roe v. Wade in January 1973, the U.S. Supreme Court ruled that restrictive state abortion laws were unconstitutional, thereby legalizing induced abortion throughout the country. As a result, the number of legal abortions increased to almost 1.6 million in 1980.
It doesn't seem all that unreasonable to surmise that legalizing abortion materially increases the number of abortions based on those figures.
CELTICEMPIRE stated that "one million women getting abortions each year didn't occur until after Roe v. Wade," & the data cited by the article that I brought up showed that it was known in 1955 (i.e. 17 years before Roe) that up to 1.2 million illegal abortions were occurring annually. I wasn't arguing that legalizing abortion didn't increase the number of abortions, because of course that simply wouldn't be true. I was, however, refuting CELTICEMPIRE's outright lie.
Taking the source you cite in context.
In 1955, experts had estimated, on the basis of qualitative assumptions, that 200,000-1,200,000 illegal abortions were performed each year.1 Despite its wide range, this estimate remained the most reliable indicator of the magnitude of induced abortion for many years. In 1967, researchers confirmed this estimate by extrapolating data from a randomized-response survey conducted in North Carolina: They concluded that a total of 800,000 induced (mostly illegal) abortions were performed nationally each year
The estimate you cite had a ludicrously high range of possible outcomes, which later research clarified at a less than one million figure.
Calling Celtic a liar based on that is quite the stretch.
