| Risk of accidental pregnancy BEST case scenario assuming PERFECT use
Per Year (assuming 100 sex acts) Per Act
No protection 8 in 10 (1 in 1.25) 1 in 125
Condoms 1 in 50 1 in 5,000
Birth Control 1 in 333 1 in 33,300
Condoms & Birth Control 1 in 1,665,000 1 in 166,500,000*
Given 100,000,000 women of child bearing age (ages 14-59*),
Unplanned pregnancies result: 100,000,000/1,665,000= 60
Risk of accidental pregnancy WORST case scenario assuming TYPICAL use
Per Year (assuming 80 sex acts) Per Act
No protection 8 in 10 (1 in 1.25) 1 in 125
Condoms 1 in 6.6 1 in 533
Birth Control 1 in 12.5 1 in 1,000
Condoms & Birth Control 1 in 6,666 1 in 533,333
533*1000=533,333
533,333/80=6,666
Unplanned pregnancies result: 100,000,000/6,666=15,000
Pregnancy rates of different contraceptives are from:

Data does not say how many times couples are assumed to have sex, so
based on information gathered elsewhere, I estimated 80-100 times to
concoct best and worst case scenarios.
Currently there are an average 1 million abortions per year

http://www.nrlc.org/abortion/facts/abortionstats.html
48% of all U.S. pregnancies (and 78% of teen pregnancies) are an
unplanned

And 4 million new babies are born per year

The below statistics give you an idea of how much safer contraception
makes us, and when compared to the numbers above, specifically how much
safer two forms of contraception make us. Of course, not all women are
having sex, so all estimates of unplanned pregnancy above and below are
exaggerated.
unplanned pregnancies result with no contraception: 100,000,000/1.25 =
80,000,000
unplanned pregnancies result with condoms alone
(perfect use): 100,000,000/50 = 2,000,000,000
(typical use) 100,000,000/6.667 = 15,000,000
unplanned pregnancies result with birth control alone
(perfect use): 100,000,000/333= 300,300
(typical use) = 100,000,000/12.5 = 8,000,000
