Abstract Prevention of unintended pregnancy among adolescents and young adults under 25 years is pivotal from an individual as well as societal perspective. In the USA, the use of long-acting reversible contraceptive (LARC) has been shown to increase, with no or little change in the use of short-acting reversible contraceptive (SARC). We assessed trends in no contraceptive, SARC, and LARC use by young women, aged between 12 and 25 years, and differences in trends within demographic groups (age, religion, ethnic background, and educational level) among these young women in the Netherlands.
