This January 25, Women’s Health Research Day champions the importance of representation in the evidence used to inform health policies and programs. In a new policy analysis, Guttmacher experts and researchers explain the shift to a more precise way of measuring contraceptive need, called unmet demand. “When we measure contraceptive need in ways that center people’s preferences, we get data that are more meaningful for policy and funding decisions,” says Jessica Rosenberg, research associate and co-author. “The ITU indicator provides insight into women’s contraceptive plans, but it only tells part of the story,” says Elizabeth Sully, Guttmacher’s director of international research. “Used alone, it risks narrowing our focus to modern method uptake just when the field is trying to expand measurement to capture the full complexity of people's contraceptive decision-making."
