I thought it sounded high. I don’t think that one in three of the general (female) population has had an abortion. But I don’t know, either.
I think that, if you divide the estimated number of abortions over a period of time by the estimated number of potentially-pregnant women, you get something between 1-to-2 and 1-to-3. However, that doesn’t spread out evenly over the population.
It’s rather like the “Half of marriages end in divorce,” canard, which “fact” was establish by dividing the number of marriages in one year by the number of divorces ... and established forever as Gospel truth. A recent attempt to track down the actual numbers came up with a result closer to 1-in-4.
I agree. It’s my understanding that the number is inflated because some women have multiple abortions. I met two of them.
