Actually, the rate of lifetime abortion in the U.S. is about 1/3. As in, ~30% of women will have an abortion in their lifetime.
If we assume that there are 150 million women in the U.S., and ALL of them are using contraception with 99% efficacy, and ALL of those who'd get pregnant would have an abortion, it only comes out to a total of 1.5 million abortions, over the next 25-30 years (length of a woman's reproductive cycle).
Not so good at math, huh? You can't even calculate the number of abortions using your supplied information. However, even if we assume what you have assumed and add the additional assumption that each woman has sex one time per year when she is fertile, then we arrive at your 1.5 million abortions/year, which is quite close to the current abortion rate (actually slightly high based on reported abortions, ~1.33 million/year).
Since obviously not EVERY woman is on birth control and having sex 100% of the time, and not ALL pregnancies would result in abortions, we can safely reduce that number at least 2-fold.
This brings us to 750'000 abortions over the next 30 years. Compare that to 40+ million abortions in the past 30 years... and tell me that you now understand the ridiculousness of your argument. (Addressed to CycloWizard).
Wrong because your math above is absurd. I will submit these calculations instead.
Assumptions:
1. 75 million women are in the age range that pregnancy is a viable outcome of sexual activity.
2. Women can become pregnant 50% of the time when they have sex (fertility, etc...).
3. These women have sex once a week (4 times a month, 52 times a year).
4. All of these women are using contraception with 99% effectiveness.
Given these numbers, the number of resulting pregnancies would be 19,500,000/year (75,000,000 women * (52 sex/woman/year) * (0.01 contraceptive failures/sex) * (0.50 pregnancies/contraceptive failure) = 19.5 million pregnancies/year). Thus, if only 5% of pregnancies resulted in abortion, it would still be 975,000/year. This is much, much higher than your completely and obviously wrong 750,000/30 years (=25,000/year). So, I think we can all see who is being ridiculous.
