An NPR article on the debate about contraceptive coverage makes the following claim:
In fact, 98 percent of Catholic women use birth control at some point in their lifetimes.
Is this claim true?
The chart that is displayed there shows closer to an 89% rate amongst catholic women. The data claiming the 98% rate came from a Guttmacher Institute study.
The main difference between the two studies is that one is focused on sexually active women who do not want to get pregnant (that CAN get pregnant) versus all women who may or may not be sexually active, or may actually want to get pregnant.
According to the Guttmacher Institute the answer is yes - 98% of sexually experienced Catholic women have used artificial contraception.
This study also finds:
Adding it all up, of the Catholic women surveyed who were sexually active, but avoiding pregnancy, 87% were using some form of contraception, 2% were using natural family planning, and 11% were relying on what I can only imagine is "pull and pray."
