Um, pretty good, considering 98% of Catholics take birth control, wear rubbers and eat meat on Fridays.
...this picture is stupid. Pre-pubescent girls and post-menopausal women don't use birth control, for obvious reasons. Women who don't have sex don't use birth control, again for obvious reasons. And finally, if you want to get pregnant, you're not going to use birth control, again for obvious reasons! This is like casting doubt on election polls because they don't include the opinions of non-citizens, felons, and children. People who have no need for birth control are completely irrelevant to a survey of the percentage of Catholic women who use birth control.
