More religious women, while less likely to be sexually active outside of marriage, are less likely to use hormonal contraception when they do have sex—a finding that fits with the conventional wisdom. The new finding Brooks and Weitzman uncovered is that when not using hormonal contraception, highly-religious women are more likely to use condoms than their less religious counterparts.
Thus, religious women’s “shortfall” in hormonal contraceptive use is compensated by both greater shares abstaining and greater shares using condoms when not using hormonal contraception, which is represented in the diagram by the red background that isn’t covered by something. (Note that religious women are not more likely to use condoms overall, but they are more likely to use condoms in the absence of hormonal contraception. Less religious women have higher rates of dual method use).

Archbishop Paul Coakley of Oklahoma City thanked state leaders Wednesday “for supporting pro-life measures” after the governor signed into law the strictest abortion ban in the country.
The Oklahoma law, prohibiting abortion from the moment of conception with few exceptions, comes ahead of a U.S. Supreme Court decision that could leave abortion legislation solely up to the states.
