So, how does one get "98% of heterosexual women in America use birth control" from "The percentage of women at risk for pregnancy who said they or their partner were using some method of birth control was high overall and ranged from 67% (Guam) to 88% (Idaho). The prevalence of birth control use exceeded 80% in 44 of 54 states (median prevalence: 84%)?" Doesn't add up...
My argument was not "98% of heterosexual women in America use birth control." My argument was "98% of heterosexual women in America have used birth control." So yes, you are correct. 98% is not a median of 84%.
I have a hard time believing that only 2% of heterosexual women (I was guessing 18 and up, but maybe they use 21?) in America are virgins who don't use birth control pills for hormonal therapy. And that's assuming that every heterosexual woman who has had sex uses birth control for some reason. Not sure I buy those two premises. Then again isn't the interwebz for spouting random "facts" that support your right to be right?
Did you flunk sex education? The rhythm method is abstinence during days the woman is fertile. Given about 25% of the population is catholic, it wouldn't be hard to see that maybe as many as 25% of women do not use birth control.
I know it's a real form of birth control, but it's also the worst chance of avoiding pregnancy. You're right Denny, I confused the two bad concepts in my mind.
