It's a classic Catch-22. Those crazy, repressed Catholic hormones mix with our ingrained birth control paranoia, and we just go ahead and fuck whatever moves without thinking about rubbers or pills.
The Guttmacher Institute, which researches sexual and reproductive health worldwide, says it used the survey data along with data on the number of abortions performed nationally to estimate abortion rates and the size of certain demographic groups. The institute found that more Protestant women obtained abortions than Catholics: Forty-three percent of women over age 17 in the 2000-2001 survey said they were Protestant, while 27 percent said they were Catholic. But Catholics were more likely to get an abortion: The abortion rate for Catholic women was 22 per 1,000 women; the rate for Protestants was 18 per 1,000 women.
According to a survey by the Center for Bio-Ethical Reform, women identifying themselves as Protestants obtain 37.4% of all abortions in the U.S.; Catholic women account for 31.3%, Jewish women account for 1.3%, and women with no religious affiliation obtain 23.7% of all abortions. 18% of all abortions are performed on women who identify themselves as "Born-again/Evangelical".
